PerkinElmer Series 200 LC Pump (HPLC) Sciex API 4000 QTrap (Mass spectrometer)

Chromatography techniques allow to separate a mixture of chemical compounds based on the physical-chemical properties of the substances. Mass spectrometer can detect the separated compounds based on their molecular weight. Liquid chromatography-mass spectrometer technique requests liquid state samples and it is suitable for the analysis of medium-volatile or low-volatile compounds. Mass spectrometer provides a great sensitivity detection, but the sample is not recoverable after analysis.
