What is the difference between MRM3 vs MS/MS/MS (MS3)? by Christie Hunter | 0 CommentsThe MRM3 workflow and the MS3 scan are functionally the same QTRAP system scan, but used with different goals in mind. The main difference is how these scans are used in the whole MS workflow. With MS3 scans, you can use these in a data dependent mode for discovery...
How do I add a retention time calibration protein to my SWATH acquisition ion library? by Christie Hunter | 0 CommentsWhen processing SWATH acquisition data, you want to use a reasonably narrow time window to reduce the chance of incorrect peak integrations and to reduce data processing time. There are currently two strategies being employed today to adjust for differences between...
Overcoming uncertainty in your PFAS analysis by Karl Oetjen | Blogs, Environmental / IndustrialJust like gum on the bottom of a shoe, the existence of per- and poly-fluorinated alkyl substances (PFAS) in our environment is a sticky one. If you’re in the field of environmental testing, then you’re all too familiar with the threat these substances have on public health. While we have learned a lot about them over the years, there is still much more to understand. With the right detection methods, we can gather the information we need to empower us to make informed decisions on reducing the risks they impose.
Selecting an LC-MS system for quantitation of pharmaceutical drug development by Kirsten Craven | Blogs, Echo MS, Pharma, QTRAP / Triple Quad, ZenoTOF 7600 systemWe understand you are busy, needing to prioritize running instruments, reporting results and managing your laboratory to meet deadlines. We created a solution guide to explain how SCIEX systems fit in the drug development pipeline to save you time evaluating options.
Nitrosamines: Where are we now? by SCIEX Community | Blogs, Pharma, QTRAP / Triple QuadNitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.
PFAS analysis in food: a robustness study in sensitivity and stability by Holly Lee | Blogs, Environmental / Industrial, Food / Beverage, QTRAP / Triple QuadThe combination of per- and polyfluoroalkyl substances (PFAS) testing, trace-level regulatory requirements and complex MS applications can be intimidating. In a recent webinar, now available on demand, SCIEX PFAS expert Craig Butt demonstrated how the new SCIEX 7500+ system can help make PFAS testing easier.
Maximize NPS analysis with accurate mass spectrometry by Pierre Negri | Blogs, Forensic, SCIEX OS software, Toxicology, ZenoTOF 7600 systemLC-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.

Sequential processing of multiple data-files in ProteinPilot by Adrian Brown | Data processing, ProteinPilot, Proteomics, QTOF, QuestionsI would like to use ProteinPilot 5.0.2 to process data-sets containing 16 wiff files acquired from fractionated peptides on a 6600 TripleTOF. A Precision T7910 workstation struggles to process four files in parallel and I would like to be able to queue sequential processing of individual files overnight. I currently use the ‘LC ‘ tab to load and process individual data-files but this leads to parallel processing. Is it possible to generate 16 .group files sequentially?
Processing ZenoTOF 7600 system data with DIA-NN software by Christie Hunter | Data processing, Life Science Research, Proteomics, SCIEX information, ZenoTOF 7600 systemDIA-NN software is a powerful software tool for processing data independent acquisition (DIA) proteomics datasets. It uses neural networks and other algorithms to identify and quantify peptides and proteins from DIA data and is specifically optimized for fast...
