Instant Expertise™: Method for optimal quant and ID results in one acquisition
Issue: Classical Auto MS/MS strategies use basically the same pre-set conditions for fragmentation; independent of the peptide amount and chroma-tographic resolution – meaning that dynamic range and MS/MS quality are compromised .
Solution: Instant Expertise Software with new autoMSMS strategies:
• IDAS (Intensity Dependent Acquisition Speed) MSMS acquisition time automatically derived from precursor intensity
• RT2 (RealTime Re-Think) RealTime Re-Think reconsiders an additional MS/MS at a higher precursor signal intensity before activating dynamic exclusion
See Application Note LCMS-81 for more details.
• Higher productivity – one acquisition method for all concentration levels
• Higher yield (> 50%) of good MSMS => higher ID rates
• High accuracy for quantitation
• Always obtain optimal results, independent of sample amount or complexity
