Quantifying steroids in biological matrices has always presented analytical challenges. Complex structures, isobaric interferences, and matrix effects often limit accuracy and throughput — demanding a new approach beyond incremental improvements.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Advancing_Steroid_Quantification_Unlocking_Sensitivity_and_Selectivity_with_the_Thermo_Scientific_Stellar_Mass_Spectrometer_6e03ce7f59.jpg" alt="Thermo Fisher Scientific: Advancing Steroid Quantification: Unlocking Sensitivity and Selectivity with the Thermo Scientific Stellar Mass Spectrometer." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Fisher_Scientific_Advancing_Steroid_Quantification_Unlocking_Sensitivity_and_Selectivity_with_the_Thermo_Scientific_Stellar_Mass_Spectrometer_6e03ce7f59.jpg 245w," sizes="100vw" width="1024" height="512">The<a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1149"> Thermo Scientific Stellar MS</a> redefines how analysts approach steroid quantification, enabling rapid method optimization through advanced scanning flexibility, complementary fragmentation mechanisms, and enhanced selectivity.Rather than focusing on a single metric, this application note demonstrates how researchers can quickly develop more effective methods by leveraging the full capability of the Stellar MS to characterize compounds comprehensively in a single acquisition.<h3>A new paradigm for analytical quantitation</h3>Traditional LC-MS approaches often rely on incremental improvements in sensitivity or speed. Stellar MS instead provides a new analytical framework, designed to optimize every parameter of quantitative method creation.Key attributes include:<ol><li>PRM vs. SRM/MRM — improving instrument efficiency Parallel Reaction Monitoring (PRM) on Stellar MS provides comprehensive ion information for each target steroid, improving quantitation accuracy and efficiency over traditional MRM methods.</li><li>Complementary dissociation mechanisms — HCD and CID Stellar’s unique ability to combine beam-type (HCD) and resonant (CID) dissociation ensures full coverage of all 17 targeted steroids. This dual-mode approach effectively overcomes neutral water loss product ions — one of the key challenges in steroid analysis.</li><li>Next-level selectivity — MS² to MS³ transition The platform’s ability to perform MS³ experiments enhances selectivity and confidence, particularly in complex biological matrices, where interferences are common.</li><li>Product ion accumulation vs. dwell time — improved ion ratios and sensitivity By accumulating product ions rather than relying on fixed dwell times, Stellar MS achieves superior ion ratio precision and reproducibility — even at low spiking levels — without sacrificing throughput.</li></ol>&nbsp;<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Fisher_Scientific_Advancing_Steroid_Quantification_Unlocking_Sensitivity_and_Selectivity_with_the_Thermo_Scientific_Stellar_Mass_Spectrometer_2_21e509451a.jpg" alt="Thermo Fisher Scientific: Advancing Steroid Quantification: Unlocking Sensitivity and Selectivity with the Thermo Scientific Stellar Mass Spectrometer: Figure 1.

In this application note, a single injection per spiking level generated 125 distinct scan events, combining:<ul><li>HCD and CID MS² experiments</li><li>Targeted MS³ scans</li><li>Positive/negative polarity switching</li></ul>This workflow enables analysts to rapidly evaluate:<ol><li>Which dissociation mechanism produces the most informative spectra</li><li>Whether MS² or MS³ is best suited for each compound</li><li>The optimal product ions for confident post-acquisition quantitation</li></ol>By providing this complete dataset in a single run, Stellar MS dramatically accelerates method optimization and validation, supporting more efficient and reliable quantitation strategies.<h3>Driving method development efficiency</h3>The real strength of the Stellar MS isn’t just its speed or sensitivity — it’s the ability to experiment, compare, and decide in one workflow. Through simultaneous HCD/CID fragmentation, MS² and MS³ switching, and polarity control, users can determine the optimal analytical conditions across complex steroid panels quickly and confidently.This approach helps labs:<ul><li>Reduce development time</li><li>Maximize data quality</li><li>Improve long-term robustness and reproducibility</li></ul><h3>Conclusion</h3>The Stellar MS platform empowers analytical scientists to move beyond incremental performance metrics toward methodological innovation.By integrating comprehensive characterization and advanced scanning control, it enables faster, more confident decisions in quantitative steroid analysis — setting a new benchmark for flexibility and precision in LC-MS.Ask the Experts: On-Demand WebinarLearn more about how Stellar MS enhances steroid profiling and quantitative workflows.

Advancing Steroid Quantification: Unlocking Sensitivity and Selectivity with the Thermo Scientific Stellar Mass Spectrometer

<h4>The problem&nbsp;</h4>We live in a “global village” but we are all different and we use many different languages to communicate.&nbsp;Even when people speak the same language, the same words may be used with different meanings. See, for example, some different uses of the word “standard” in English – a normative document, a solution of known concentration or even a type of flag.&nbsp;Even in the same area of activity misunderstandings do occur which may result in a waste of time and money, or even worse consequences.&nbsp;When talking about laboratory tests, lack of a full understanding of key terms and inappropriate translations leaves room for different interpretations of stated requirements. For example, there have historically been a number of different but related uses of the term ‘detection limit’. This may lead to inadequate fulfilment of those requirements, thus becoming an obstacle to the production of analytical data that is fit for its intended use. A shared interpretation of concepts related to quality in measurement between laboratories and accreditation bodies is also crucial for a fair and harmonised approach to laboratory assessment across the world.&nbsp;<h4>A common language&nbsp;</h4>We need a common language; clear and unambiguous. We need a common vocabulary to provide consistent definitions of concepts with their associated terms. To this end, several organisations participate in a joint effort to develop and maintain an international vocabulary of metrology (VIM) [1], which aims to achieve a unique understanding of concepts related to measurements across all sectors. The VIM is a normative reference in the standards ISO/IEC 17025, ISO 15189 and ISO/IEC 17043, and is therefore a key document for all organisations seeking accreditation.&nbsp;<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_You_talk_we_understand_The_way_out_of_the_tower_of_Babel_Standards_8d947dbd5f.jpg" alt="Eurachem: You talk, we understand – The way out of the tower of Babel_A common language" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_You_talk_we_understand_The_way_out_of_the_tower_of_Babel_Standards_8d947dbd5f.jpg 245w," sizes="100vw" width="1126" height="499"><h4>Is this enough?&nbsp;</h4>For laboratory staff some problems still stand and need to be addressed:&nbsp;<ul><li>Many people are confused about both concepts and terms.&nbsp;</li><li>It may be difficult to understand the “formal” VIM definitions – they are short statements intended to apply to many different measurement sectors.</li><li>Translations into local languages may add to the confusion, e.g. if different terms are used in different sectors for the same VIM concept and the translator overlooks this issue.</li><li>Some substantial changes to terminology have been made in an attempt to accommodate chemical and biological measurements. Some “old” concepts still stand but have new names, e.g. “within laboratory reproducibility” vs. “intermediate precision”.&nbsp;</li></ul>To address these issues Eurachem has produced a guide [2] which provides an accessible reference containing simple and in context explanations of terms most relevant to analysts, with additional examples relating those concepts to chemical and biological measurements.&nbsp;<h4>Do you understand the meaning of these terms?&nbsp;</h4>Are you interested in a quantity or a quality? Depending on the answer, will you use a measurement procedure or an examination? Is method verification the same or less demanding than method validation? Do you need a calibration or just performance verification? Do you have a measurement standard in your laboratory? Is metrological traceability something you worry about? These are examples of the terms supporting the reliability of any measurement result that need to be clearly understood.&nbsp;<h5>Example – Accuracy, trueness, precision: are they synonyms?&nbsp;</h5><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_You_talk_we_understand_The_way_out_of_the_tower_of_Babel_accuracy_231e1e005e.jpg" alt="Eurachem: You talk, we understand – The way out of the tower of Babel_Example – Accuracy, trueness, precision" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_You_talk_we_understand_The_way_out_of_the_tower_of_Babel_accuracy_231e1e005e.jpg 146w," sizes="100vw" width="754" height="807"><ul><li>Closeness between measurement results (relating to the concept of precision)</li><li>Closeness of the average of the measurement results to a reference value (relating to the concept of trueness)&nbsp;</li><li>Closeness of an individual measurement result to the true value (relating to the concept of accuracy)&nbsp;</li></ul>The different situations in the figure show the effect of:&nbsp;<ol style="list-style-type:lower-latin;"><li>poor precision and trueness (imprecise and biased)&nbsp;</li><li>good precision, poor trueness (precise but biased)&nbsp;</li><li>poor precision, good trueness (imprecise but unbiased)&nbsp;</li><li>good precision and trueness (precise and unbiased)&nbsp;</li></ol>Improving both precision and trueness is expected to improve accuracy.&nbsp;<h4>Is all this relevant to you?&nbsp;</h4>Do you work in a laboratory, either as an analyst, quality manager or director? Are you involved in other activities related to analytical work, such as providing proficiency tests, producing reference materials or accrediting any such activity? Do you teach or study subjects related to measurements? Do you use measurement results or prescribe how to use them? If the answer is yes to any of these questions, the following reference documents are also for you.
