Delayed production timelines. Reworks across teams.If you’re working with monoclonal antibodies (mAbs) or other biopharmaceuticals, you already know the challenge: biological reactions are variable.Unlike traditional small-molecule drugs, with simpler and more predictable chemical structures, biotherapeutics exist in a dynamic state of microheterogeneity — no two batches are ever truly identical.Whether undergoing production, processing, or storage, these compounds often undergo unwanted side reactions like glycation, deamidation, charge variation, and aggregation, which can compromise product safety and efficacy.Finding robust and dependable ways to monitor these critical quality attributes (CQA) and protect therapeutic integrity is even more pressing, as regulatory agencies demand comprehensive characterizations.While analytical techniques like liquid chromatography (LC) and mass spectrometry (MS) play a fundamental role in CQA analysis, the increasing complexity of analytical tasks is forcing the requirements of instruments to grow.The good news? <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/blog/analyteguru/biopharma-boost-how-2d-lc-went-from-expert-only-to-routine/">Targeted two-dimensional LC (2D-LC)</a> workflows that can handle analytical complexity and support straightforward method development without any manual fluidic changes are already here.Let’s explore how your lab can use 2D-LC coupled with ultraviolet detection (UVD) or high-resolution accurate mass spectrometry (<a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products?category=22&amp;manufacturerItems=3">HRAM-MS</a>) to monitor the CQAs of intact mAbs in real time (Figure 1).<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Monitoring_m_Ab_Manufacturing_the_Easy_Way_with_Switchable_2_D_LC_UV_MS_2_8ee6b79638.jpeg" alt="Thermo Fisher Scientific: Monitoring mAb Manufacturing the Easy Way with Switchable 2D‑LC-UV-MS: Figure 1.

ProA affinity chromatography for titer determination and isolation of the mAb from host cell material and media components. The purified fraction is then sent via automated heart‑cut transfer straight into the 2D. The 1D elution conditions facilitate optimal mAb capture at the SCX column in the 2D.</li><li>ProA‑SCX to see charge drifts. Gradient elution of the SCX column in the 2D to separate acidic and basic variants from the main peak.</li><li>ProA‑SCX‑SEC to see aggregation risks. The SCX column is switched in line with the SEC column to resolve the monomer, low‑molecular‑weight (LMW), and high‑molecular‑weight (HMW) fractions. The SCX column here acts as a trap and refocusing stage, releasing the mAb into SEC in a narrow band by a step increase to high ionic strength. The trap/elute procedure is critical to yield sharp peaks downstream, as SEC cannot refocus bands, broadened by the loop volume.</li></ul>Together, these workflows support both early risk detection and informed corrective action without adding analytical complexity.<h3>UVD or MS? How to pick the right tool for the job</h3>With switchable 2D-LC workflows, you can select different detection options in the 2D: UVD or HRAM-MS (Figure 5). The fluidic setups differ slightly, but you must always use a fully volatile buffer system with the MS option.<h4>Here’s how to choose the right setup:</h4><ul><li>UVD is ideal for routine, in‑time process control of established reactions.

SIELC Alltesta Mini UV-Vis Detector

The Alltesta™ UV-Vis Multi-wavelength Mini Detector is a compact and versatile device that can continuously monitor the optical properties of solutions flowing through it.

The Alltesta™ UV-Vis Multi-wavelength Mini Detector is a compact and versatile device that can continuously monitor the optical properties of solutions flowing through it. The Mini Detector is ideal for use in HPLC, Flow Injection Analysis (FIA), and preparative and flash chromatography.
The device comes standard with four different wavelength channels, including 470 nm (Blue), 520 nm (Green), 630 nm (Red), and a choice between 255 nm or 275 nm for the UV channel. The Mini Detector features a simple setup process with a USB interface that allows it to communicate with the <a href="https://lcms.labrulez.com/products/1242">Alltesta™ Gradient Automated Analyzer</a> or <a href="https://lcms.labrulez.com/products/1243">Alltesta™ Cromite Analyzer</a> or integrate with other instrumentation.
Powered solely by its USB port, this mini detector is capable of monitoring multiple analytes simultaneously. It has a low optical cell volume of &lt; 3 µL, which results in minimal dispersion even at low flow rates, and can collect data at rates of up to 20 sps for all four channels, making it suitable for demanding applications. The Mini Detector boasts low noise and linearity over more than 4 orders of magnitude.
In addition to its compact size and versatility, the Mini Detector also has zero warm-up time and exceptional durability. The detector cell volume is available in two sizes: 3 μL and 10 μL.

ARC Solvere Universal HPLC Detector

The Solvere™ is a new LC detector that brings the benefits of the Flame Ionization Detector (FID) to LC. 
Using ARC’s expertise in catalysis and reactor design, a novel method was developed for removing volatile compounds, which allows for the use of both aqueous and organic solvents with the detector. 
Non-volatile components in the sample stream are transformed into the gas phase, converted to methane, and then detected by the FID with a linear range of five orders of magnitude.
ARC Solvere is designed for quantitation of compounds where GC ends with a range up to large 1M+ Da molecules. In addition, Solvere works with a myriad of mobile phases, additives, and gradients, with unprecedented linear range, uniformity and robustness.

<h3>Why is it important?</h3>
<ul>
<li>Mobile phases are effectively separated from non-volatile analytes</li>
<li>Analytes are converted into methane for universal FID detection</li>
<li>Compatible with gradients and organic solvents</li>
<li>A variety of molecules such as proteins, peptides, and sugars give a universal carbon response</li>
</ul>
<blockquote>
FOR USE WITH ANY LC MODEL
</blockquote>
<h3>Benefits of the Solvere</h3>
<ul>
<li>Analyte response independent of mobile phase composition</li>
<li>Conversion of analytes to methane for universal FID response</li>
<li>5 orders of magnitude range</li>
<li>~10 ppm LOD</li>
<li>Standalone and automated</li>
</ul>
