GC/Mass Spectrometer

Features: 

 

Thermo Scientific TSQ Quantum XLS tandem GC/MS/MS and Trace MS EI and negative ion CI sources Unit mass resolution Lower detection limit < 100 fmole Interfaced to a Trace GC’s equipped with autosamplers

These mass spectrometers give investigators a simple to use tool for the analysis of small, volatile molecules isolated from biological sources. These instruments are used to quantify F2-isoprostanes, aldehydes generated by lipid oxidation, oxy-sterols and phytanic acids. When sample mass is limited we can use this instrumentation to measure cholesterol and methylated fatty acids (FAME). The Trace MS were purchased with grant funds from the North Carolina Biotechnology Center and the Winston-Salem Foundation. The TSQ was purchased with funds from the NIH Shared Instrumentation Program.
