Maximize NPS analysis with accurate mass spectrometry
LC-MS/MS is a powerful analytical tool in forensic toxicology testing that can support a variety of testing regimes such as screening, confirmation and quantitative workflows. More specifically, analysis of NPS using LC-MS/MS provides many advantages, including the ability to reliably detect new drugs and their metabolites from a variety of biological matrices.
Unlock the benefits of nominal mass spectrometry for NPS analysis
The development of analytical methods for the detection and quantitation of drugs and metabolites in a range of biological matrices is a challenging process. Forensic toxicology labs need a reproducible and reliable methodology to ensure the robustness of the data and the quality of the results. They also need robust and sensitive instrumentation that can detect drugs at trace levels with high specificity, especially when it comes to novel psychoactive substances (NPS), which can be difficult to monitor and control.
What has the Echo® MS system done for the pharma industry? (And don’t just take our word for it!)
SCIEX was very proud to have an illustration of the Acoustic Ejection Mass Spectrometry (AEMS) technology that powers the Echo® MS system on the front cover of the Journal of the American Society for Mass Spectrometry in January 2023. The associated article—Ultrahigh-Throughput Intact Protein Analysis with Acoustic Ejection Mass Spectrometry—was co-authored by scientists from SCIEX and Merck.
Back to the new basics: Part 1 | Making the leap from GC-MS to LC-MS
Producing accurate results quickly in a demanding environment is no easy feat for analytical scientists. What’s more, many of us are constantly questioning ourselves—I certainly am—about whether we are employing the best technique for the analysis at hand.
It’s an overwhelming thought, considering the wide range of tools that are available to choose from, each of which offers varying levels of capacity, sensitivity, selectivity, specificity and cost. How do you meet the unique needs of your organization without breaking the bank? I get it, and I’m not here to convince you it’s easy. My aim is to guide you through the process to help you make the right decision for you.
How does automatic calibration work on the QTOF, TripleTOF and ZenoTOF systems?
When you think about calibration of a mass spectrometer, there are actually two aspects to consider. There is the accuracy of the calibration (that it is correct when calibration is performed) and the stability or precision of the mass calibration (that it remains...
What is SWATH acquisition and what are the critical acquisition attributes?
In data-independent acquisition strategies like SWATH acquisition, an expanded mass isolation window is stepped across a mass range covering the mass-to-charge (m/z) distribution of peptides and a full scan MS/MS spectrum is collected at each step. Post-acquisition,...
Controlling the M5 MicroLC system with SCIEX OS software using contact closure
Contact closure can be used to control external devices that are not directly controlled by SCIEX OS software. A sample batch is first created in the SCIEX OS software for MS acquisition, and then a similar batch is created on an external LC device with the required...
The risky business of aflatoxins in milk
If you’re in the dairy or food testing business, you know the threat aflatoxins pose. Aflatoxins are a type of mycotoxin produced by Aspergillus parasiticus, aspergillus flavus , and rarely aspergillus nomius.1 These are likely the most extensively researched group of mycotoxins because of their adverse health effects.2 What’s more, they are widely found in a variety of crops, namely maize, tree nuts, and spices. Believed to be primarily caused by rising temperatures and humidity, these naturally occurring fungi grow on crops in the field, or during storage of feed and raw materials, where they can potentially produce toxins that enter the food chain.
Intabio acquisition expands SCIEX portfolio of impactful solutions to accelerate biotherapeutic development
Due to the nature of their production, biotherapeutics are difficult to manufacture. Growth conditions, purification protocols and formulation requirements can introduce unintended modifications into the protein structure that may affect its efficacy and safety.
Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
