The advent of commercial high-performance liquid chromatography instruments coupled to tandem mass spectrometers offers the potential for medium- to high-throughput profiling of serum steroids using small quantities of sample.

Here, we review the physical principles of mass spectrometry, the instrumentation used for these techniques, the terminology used in this field and applications to steroid analysis.

Stationary phases versus mobile phases. SpringerLink This makes it ideal for the analysis of the hundreds of relatively low molecular weight compounds found in environmental materials. In addition, functionalised compounds may require chemical modification derivatization , prior to analysis, to eliminate undesirable adsorption effects that would otherwise affect the quality of the data obtained.

Samples are usually analyzed as organic solutions consequently materials of interest e. The sample solution is injected into the GC inlet where it is vaporized and swept onto a chromatographic column by the carrier gas usually helium.

The sample flows through the column and the compounds comprising the mixture of interest are separated by virtue of their relative interaction with the coating of the column stationary phase and the carrier gas mobile phase.

The latter part of the column passes through a heated transfer line and ends at the entrance to ion source Fig. File Name: gc ms principle and applications pdf. GCMS Pre-lab lecture.
