Question
Which of the following gases is unsuitable for use as a GC carrier gas?Select one:a.Oxygenb.Nitrogenc.Argond.Helium
Solution
The unsuitable gas for use as a GC (Gas Chromatography) carrier gas among the options provided is Oxygen.
This is because Oxygen is reactive and can potentially react with the sample or the column, leading to inaccurate results. In contrast, Nitrogen, Argon, and Helium are all inert gases, meaning they do not readily react with other substances. This makes them suitable for use as carrier gases in GC.
