3 Ways our New LC-MS Triple Quads Improve
Residue Analysis
Complex Matrices
Large Sample Numbers
Low Concentration
Today’schallenges in quantitative mass spectrometry
demanded that we elevate
triple quad capabilities
Small Sample Amounts
Extreme quantitative value with best-in-class sensitivity
Thermo Scientific™TSQ Endura MS
Thermo Scientific™TSQ Quantiva MS
Extreme quantitative performance with unrivaled attogram level sensitivity
New GenerationTriple Quadrupole LC-MS systems
How do our new Triple Quadrupole systems improve residue analysis?
SPEED
ChallengeHigh volume multi-residue analyses in short run times

Traditional Triple Quads decline in sensitivity, even at lower SRMs per second
New Thermo Scientific™ Triple Quadrupole systems maintain sensitivity up to 500 SRMs per second
High sensitivity at every speed
More points across the peak means
more reproducible results and allows
for faster run times
