Liquid chromatography triple quadrupole mass spectrometry
The LC/QqQ-MS instrument (Agilent 6470) with the JetStream technology is one of the most sensitive triple quadrupoles in the market.
It provides comprehensive screening for a large number of compounds and it gives high confidence by monitoring two or more transitions.
Usual detection limits range from 0.1 ng/L to 10 ng/L for pesticides and from 1 ng/L to 50 ng/L for pharmaceuticals. Linearity of response is over 3 orders of magnitude.
This system is coupled to the new Infinity II HPLC, which provides both improved peak resolution and rapid analysis.
