AB SCIEX 4000 QTRAP® 


The 4000 QTRAP® LC/MS/MS System is a hybrid triple quadrupole/linear ion trap mass spectrometer coupled to an Agilent 1200 quaternary HPLC.  This tandem mass spectrometry system has high-sensitivity and is ideal for quantification of small molecules in complex biological and environmental matrices.  The LC/MS/MS system provides specificity of an analyte in complex matrices such as the blood which conventional HPLC methods cannot achieve. In addition to targeted quantification analysis, the system can perform MS experiments (such as MS3) that aid in structural characterization and identification of unknown compounds. Our current workflow includes targeted quantitative analysis of small organic compounds including metabolites, pharmaceuticals and pesticides. Theoretical and practical (hands-on) training is provided for those who wish to use the instrument on long term basis.

Current cost for using the 4000 QTRAP® system is $15/hr for researchers within the Health Sciences Building and $30/hr for other researchers at the University of Saskatchewan. External users should contact Dr. El-Aneed (anas.el-aneed@usask.ca) for pricing as per the University of Saskatchewan guidelines. Please contact Deb Michel (dlm137@mail.usask.ca) for permission to book online.

Thermo TSQ Vantage (with FAIMS) and Agilent 1290 UHPLC

 

The TSQ Vantage is a triple quadrupole mass spectrometer. When used for quantification, the first quadrupole will selects the m/z ratio(s) of an ion(s) corresponding to the analyte(s) of interest, the second quadrupole will fragment the ion(s), and the third quadrupole will monitor the m/z ratios of specific fragments.  The result is a very sensitive and selective means to quantify compounds of interest present in complex matricies.  The system is coupled to an Agilent 1100 liquid chromatography system for use in developing LC-MS methods for a variety of biological applications including the analysis of known metabolites of interest in agricultural crops and quantification of drugs and metabolites in the pharmaceutical industry.

For methods in which high background persists, an ion does not yield useful fragmentation, or if there are isomeric constituents within the matrix, a FAIMS device also can be employed (LC-FAIMS-MS).  FAIMS is a type of ion mobility (high field asymmetric waveform ion mobility spectrometry) that separates gas phase ions at atmospheric pressure based on a mechanism that is complementary to both LC and MS and therefore gives very high selectivity.
