GC Instrument Components

Sample Introduction in Gas Chromatography

Students will learn to: Describe the operational principle of different entry-level techniques such as split/splitless, on column, PTV, thermal desorption-pyrolysis, purge and trap Differentiate various types of GC sample introduction methods and determine their suitability for specific analytes in different matrices Interpret the impact…

Gas Chromatographic Columns

Students will learn to: Differentiate different types of columns (i.e., WCOT, PLOT, packed), their dimensions, applicability and diffusion factors affecting the separation Evaluate suitability of common stationary phases for different analytes Distinguish types of interactions between the analytes and stationary phase …

Gas Chromatographic Detectors

Students will learn to: Evaluate the suitability of three common detectors (FID, TCD, and ECD) for different analytes Explain the operation principle of these detectors Differentiate these detectors in terms of selectivity and other properties (destructive, bulk, concentration/ mass depending) with regard to their…
