Why compromise? The benefit of high resolution in MS and MS/MS for qualitative and quantitative analysis using a SCIEX TripleTOF System


Available on demand

The most often cited advantages of LC-MS are selectivity, sensitivity, and broad applicability.  For decades, and still today, the use of selected reaction monitoring (SRM) on triple quadrupole (QqQ) offers a degree of selectivity and sensitivity that is the gold standard for targeted quantitative bioanalysis.  The advent of MS instrumentation with resolving power in excess of 30,000 resolution has paved the way to more generic acquisition methods, with little tuning required, and where data can be extracted post-acquisition with high degree of selectivity using narrow XIC derived from chemical formula.  Using this approach, LC separation becomes crucial in the selective detection of isoforms and isobaric interferences.  To reduce the dependency on LC separation, acquisition strategies that offer the ability to collect both MS and MS/MS data with high resolving power simultaneously provide the highest degree of selectivity and flexibility.  This webinar provides examples of the benefit of such acquisition strategies on a SCIEX TripleTOF high-resolution LC-MS System.

What will you learn?

  • How HRMS data can provide a high level of selectivity for both qualitative and quantitative analyses
  • How to utilize high-resolution MS and MS/MS data for selective isoform detection
  • How multiple acquisition strategies on the SCIEX TripleTOF LC-MS System can be utilized to maximize workflow flexibility

Who may this interest?
