Jul 30, 2018 · Abstract. In gas chromatography (GC), the sample is vaporized and injected onto the head of a chromatographic column. Elution is brought about by the flow of an inert gaseous mobile phase such as helium, argon, nitrogen, carbon dioxide, and hydrogen. In GC, the mobile phase does not interact with molecules of the analyte, and it only transports

The simplicity and ruggedness of IC often requires no need to prepare a sample before injection. In many cases, a simple dilution of the sample with deionized water is all that’s needed. Sometimes more is required to protect the column by removing contaminants or particles or to enhance the sample to make it detectable.
