In GC, a mixture of volatile compounds with differential migration passes through a column containing solid or …
WebGC-MS can be used to study liquid, gaseous or solid samples. Analysis begins with the gas chromatograph, where the sample is effectively vaporized into the gas phase and separated into its various components using a capillary column coated with a stationary (liquid or solid) phase.
