This study evaluates ion chromatography with electrical conductivity and UV absorbance detection for quantifying chloronitramide, a recently identified chloramine decomposition product, in tap water. Method performance showed strong agreement with HILIC–UHRMS results, enabling reliable detection across diverse water matrices.Chloronitramide was detected in both chloraminated and free chlorine systems, marking its first reported occurrence in the latter. The developed IC methods support large-scale monitoring of chloronitramide in drinking water, with UV detection providing reduced measurement bias and improved analytical reliability.<blockquote><h4>The original article</h4><h4><a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acs.estlett.5c01218">Chloronitramide Anion Quantitation in Tap Waters by Ion Chromatography with Electrical Conductivity and Ultraviolet Absorbance Detection</a></h4>Jason A.

Formats and hyperlinks were adapted from the original.<div>After ∼45 years since it was first detected in chloraminated water <a href="javascript:void(0);">(1)</a> and more than 30 years since its prior characterization efforts, <a href="javascript:void(0);">(2−5)</a> chloronitramide anion (Cl–N–NO2–) was identified as a decomposition product of inorganic chloramines. <a href="javascript:void(0);">(6)</a> In a limited survey of chloraminated tap waters in the United States, Cl–N–NO2– was found in all samples tested (n = 40) at a median concentration of 23 μg L–1 and first and third quartiles of 1.3 and 92 μg L–1, respectively. Although its toxicity is currently unknown, Cl–N–NO2– forms at levels comparable to some regulated disinfection byproducts (DBPs) but lower than others. For example, the Environmental Protection Agency (EPA) maximum contaminant levels (MCLs) for the mass-based sums of four trihalomethanes is 80 μg L–1 and five haloacetic acids is 60 μg L–1; <a href="javascript:void(0);">(7)</a> however, the chlorite MCL is over 1 order of magnitude greater, at 1 mg L–1. The Cl–N–NO2– formation pathway contrasts that of most other DBPs, which are formed by reactions between a disinfectant and source water precursors, such as natural organic matter (NOM) and/or bromide. <a href="javascript:void(0);">(8,9)</a> Cl–N–NO2– is formed by monochloramine (NH2Cl) or dichloramine (NHCl2) reacting with nitronium cation (NO2+), <a href="javascript:void(0);">(6)</a> a reactive nitrogen species formed during chloramine decomposition. <a href="javascript:void(0);">(10,11)</a> In this regard, Cl–N–NO2– is an intrinsic DBP, <a href="javascript:void(0);">(12)</a> like chlorate and perchlorate in hypochlorite feedstocks. <a href="javascript:void(0);">(13−16)</a> As chloramines are inherently unstable and autodecompose under typical conditions in drinking water systems, <a href="javascript:void(0);">(17−19)</a> Cl–N–NO2– is likely present in all waters where chloramines are used. This includes systems where chloramines are formed intentionally and free chlorine systems containing source water ammonia. <a href="javascript:void(0);">(20)</a> To facilitate Cl–N–NO2– occurrence studies and better understand its formation in tap water, analytical methods are needed for Cl–N–NO2– quantitation that leverage common instrumentation in drinking water laboratories.The discovery of Cl–N–NO2– was supported by its quantitation in chloraminated tap waters by hydrophilic interaction liquid chromatography–ultrahigh-resolution mass spectrometry (HILIC–UHRMS). <a href="javascript:void(0);">(6)</a> This method has a limit of detection (LOD) of 0.17 μg L–1 and a limit of quantitation (LOQ) of 0.58 μg L–1. However, the instrumentation required for HILIC–UHRMS (i.e., orbitrap mass spectrometers) is not widely accessible due to its high capital cost and operation and maintenance requirements, limiting collection of Cl–N–NO2– occurrence data. Cl–N–NO2– reference materials were previously isolated from mixtures containing common anions (e.g., chloride, nitrite, nitrate, sulfate, phosphate) at concentrations up to ∼100 mM using ion chromatography (IC) with electrical conductivity (EC) and ultraviolet absorbance (UV) detectors. <a href="javascript:void(0);">(6)</a> Given Cl–N–NO2– is an anion and has a molar absorptivity (ε) peak maxima at 243 nm of ε243 = 5,310 M–1 cm–1, <a href="javascript:void(0);">(6)</a> Cl–N–NO2– quantitation may be possible by IC-EC and/or IC-UV243, but the applicability of these methods at μg L–1 levels is unknown. IC methods could be a cost-effective alternative to MS-based methods and adopted at drinking water utilities and commercial water analysis laboratories, enabling widescale Cl–N–NO2– occurrence studies. The objective of this study is to assess IC-EC and IC-UV243 for Cl–N–NO2– quantitation in tap waters at μg L–1 levels. Cl–N–NO2– quantitation by IC-EC and IC-UV243 was compared to HILIC–UHRMS across an unprecedented range of Cl–N–NO2– concentrations in tap waters from U.S. residential homes.<h4>2. Materials and Methods</h4><h5>2.1. Ion Chromatography System</h5>A Metrohm 850 Professional IC equipped with an autosampler, suppressor, two electrical conductivity detectors, and an 887 Professional UV/vis detector was used to isolate Cl–N–NO2– standard reference materials and quantify Cl–N–NO2– in tap waters. Two Metrosep A Supp 7 separation columns were used, each 250 mm in length with a 4.0 mm diameter, one for Cl–N–NO2– isolation that had been used extensively (&gt;10,000 injections) and regenerated to maintain adequate anion separation and the second newly acquired for Cl–N–NO2– quantitation in drinking water matrices. Both IC columns consist of a PEEK housing packed with a poly(vinyl alcohol) carrier material with quaternary ammonium groups, 5 μm particle size, 15 MPa maximum pressure, 1.0 mL min–1 maximum flow rate, pH range 3–12, and temperature range of 20–60 °C. Na2CO3 eluent concentrate (Metrohm) was diluted 100× to 3.6 mM for Cl–N–NO2– isolation and 25× to 14.4 mM for Cl–N–NO2– quantitation.<h4>3. Results and Discussion</h4><h5>3.4.

For IC-EC, the R2 (n = 12) was 0.991 (<a target="_blank" rel="noopener noreferrer" href="https://pubs.acs.org/doi/10.1021/acs.estlett.5c01218#fig2">Figure 2</a>A) and the average residual (𝑟𝑖⎯⎯⎯) was +3.2 μg L–1, indicating an overall positive bias. For IC-UV243, the R2 (n = 12) was 0.997 and the&nbsp;𝑟𝑖⎯⎯⎯ was 0.0 μg L–1, indicating no overall bias. Therefore, the accuracy and precision of Cl–N–NO2– quantitation by IC-UV243 exceeded that of IC-EC for the tap waters tested. This is the first report, to the best of our knowledge, of Cl–N–NO2– presence in chlorinated tap waters. Although the Cl–N–NO2– concentrations are lower compared to chloraminated tap waters, this finding suggests that Cl–N–NO2– exposure is more widespread and additional formation pathways such as breakpoint chlorination could be relevant, as previously speculated. <a href="javascript:void(0);">(6)</a> The Cl–N–NO2– concentration maximum observed in the chloraminated tap waters (315 μg L–1) is greater by a factor of about three compared to that in prior work, <a href="javascript:void(0);">(6)</a> illustrating a pressing need for additional occurrence studies to capture its full range in water systems.We demonstrated that IC-EC and IC-UV243 can be used to accurately quantify Cl–N–NO2– in tap waters with minor modifications to the IC system (i.e., 5 mL injection loop and 14.4 mM Na2CO3 eluent) using standards formulated in 1 mM borate buffer at pH 9. While the lowest LOD (5.8 μg L–1) and LOQ (8.2 μg L–1) are greater than those for HILIC-UHRMS (0.17 and 0.58 μg L–1, respectively), the IC methods are accurate within an environmentally relevant range, with Cl–N–NO2– at levels up to about 315 μg L–1. Spike recovery experiments indicate matrix effects were negligible for Cl–N–NO2– quantitation by IC-EC and IC-UV243 for concentrations &lt;50 μg L–1 (i.e., P&lt;50&nbsp;μg&nbsp;L–1 &gt; 0.05). IC-based quantitation methods were strongly correlated with HILIC–UHRMS (R2 ≥ 0.991) and unbiased for quantitation by IC-UV243 peak area. Cl–N–NO2– may continue to form in tap waters containing a chloramine residual, particularly at pH ≲ 8 where chloramines decompose more readily. <a href="javascript:void(0);">(29)</a> A quenching agent/procedure has not yet been identified for chloramines that does not impact Cl–N–NO2–. Thus, the time between sample collection and analysis should be minimized (&lt;1 day, if possible) to get the most accurate assessment of Cl–N–NO2– occurrence until if/when a suitable sample preservation procedure is developed. Nevertheless, the IC methods developed and validated here can be adopted by water utilities and testing laboratories for widespread Cl–N–NO2– monitoring campaigns.</div>

<h4>Food Safety Webinar Series: When Food Meets the Lab</h4>Food testing in the region still revolves around “legacy” contaminants that decide release, rejection, and recall discussions - veterinary drug residues, pesticide residues and fumigants, and toxic elements including species-sensitive forms, in different food matrices. This 3-part series is built for audiences where regulatory expectations reference Codex-based frameworks, country-specific legislative guidelines, and import/export-market requirements that influence testing scope, reporting limits, and confirmation criteria. Each webinar focuses on the analytical factors that drive outcomes: matrix effects and co-extractives, trace-level quantitation, transition/ion-ratio checks, interference control, and reportable result logic.Keynote expert speakers will set the regulatory context, give a glimpse of the current trends, and future implications. Agilent workflow segments map these needs to sample preparation nuances, LC-MS/MS for multi-class residues, GC-MS/MS and headspace GC for residue/fumigant markers, and ICP-MS plus LC-ICP-MS for heavy metals and speciation, including QC structures and data review patterns used in high-throughput labs, to name a few.<h5>Webinar Series Details</h5><ul><li>Register once to attend the complete 3-part series</li><li>Submit your questions beforehand</li><li>Access recorded sessions anytime within one year</li><li>Certificate of attendance will be provided to all attendees</li></ul><h4>Part 2: Pesticide Residues &amp; Fumigants Edition</h4>Pesticide residue testing is shaped by Codex/EU-aligned expectations that frequently drive import decisions, while fumigant markers remain high-scrutiny topics for ingredients and finished foods, especially in spice, grain, seed, and produce supply chains. This webinar connects the regulatory context to method choices and result interpretation: broad-scope multi-residue coverage versus matrix complexity, QuEChERS-based extraction and cleanup, split-platform workflows (LC-MS/MS and GC-MS/MS). For fumigants, the focus includes sample handling for volatility, targeted measurement approaches for ethylene oxide/2-CE and phosphine-related testing where relevant, and reporting pitfalls that trigger disputes.&nbsp;<blockquote>Presenter: Dr. Vandana Tripathy (Principal Scientist &amp; Network Coordinator, AINP on Pesticide Residues, ICAR-IARI; FSSAI Scientific Panel on Pesticide Residues, India)Presenter:&nbsp;Dr. Yu-Feng Zhang (Application Engineer, Agilent Technologies, Singapore)</blockquote>

<h4>Scalable workflows are no longer a nice‑to‑have in proteomics, they’re essential.</h4>In this upcoming webinar series, we explore how standardized, automated proteomics workflows are enabling reproducible results at scale—from discovery to translational and applied research. Hear directly from experts and users as they share practical insights on building robust, high‑throughput workflows that keep pace with growing sample volumes, increasing complexity, and real‑world laboratory demands.Join us to learn how scalable proteomics workflows are moving from promise to practice.<h5>Automated Mag-Net Enrichment Unlocks Deep and Cost-Effective LC-MS Plasma Proteomics</h5><ul><li>Salla Keskitalo, PhD, LSRI Director Viikki Proteomics Unit, University of Helsinki</li></ul>Plasma is an ideal material for proteomics due to its diverse protein content reflecting physiological and pathological states, and its compatibility with minimally invasive sampling. Deep proteomic profiling of plasma is limited by high-abundant proteins that mask the detection of low-abundant proteins. To overcome this, we compared five plasma protein enrichment methods, Mag-Net, ENRICHplus, ENRICHiST, EasySep, and EXONET, against neat plasma using LC-MS proteomics. All five methods substantially increased protein identifications, with Mag-Net, ENRICHplus, EasySep, and EXONET yielding up to 4200 proteins per sample, over 7-fold more than neat plasma, using a 44-minute gradient on the Evosep One and data-independent acquisition on the timsTOF Pro 2. These methods enriched extracellular vesicle-associated proteins while effectively depleting high-abundant proteins. To further enhance performance and scalability, we optimized the Mag-Net protocol by increasing the plasma-to-bead ratio and automated the workflow, including Evotip loading, on the Biomek i5 liquid handler. The automated Mag-Net, combined with the Orbitrap Astral mass spectrometer, yielded up to 4500 proteins per sample with a throughput of 100 samples per day. The automated Mag-Net enrichment strategy enables affordable, scalable, high-throughput LC-MS plasma proteomics, supporting biomarker discovery across large cohorts.<h5>Topic to be announced</h5><ul><li>Joachim Smollich, PhD Student, Faculty of Biology, Department of Molecular Cell Biology, Weizmann institute of science</li></ul>
