Sentence examples for using the multiple reaction from inspiring English sources

A liquid chromatography tandem mass spectrometry method (LC MS/MS) was developed for determining the twelve analytes using the multiple reaction monitoring mode (MRM).

Samples were homogenized in chloroform:methanol (1 2 (v/v)) and analyzed by direct flow injection on a triple-quadrupole mass spectrometer (API 4500 QTRAP MS/MS; Sciex Applied Biosystems, Toronto, ON, Canada) in the positive ionization mode using the multiple reaction monitoring (MRM) method.

Data were acquired using the multiple reaction monitoring (MRM) scan mode.

When coupled to a triple quadrupole tandem mass spectrometer (QQQ-MS/MS), it can achieve high sensitivity and selectivity by using the multiple reaction monitoring (MRM) scan mode without the baseline chromatographic separation of target analytes.

The elutes were used for HPLC-ESI-MS/MS separation in a HPLC (Agilent 1200, Agilent Technologies, CA) and then quantitation in a hybrid triple quadrupole/linear ion trap mass spectrometer (ABI 4000 Q-Trap, Applied Biosystems, CA) using the multiple reaction monitoring (MRM) and information dependent acquisition (IDA) mode.
