Types of GC Columns

100 Percent Dimethyl Polysiloxane

• The 100 Percent Dimethyl Polysiloxane is one of the highest performance GC columns that has a non-polar base, which makes it suitable for the analysis of many diverse chemicals and mixtures. It is one of the stronger columns and has a high level of robustness and the ability to handle the more volatile compounds that are to be studied.

Polyethylene Glycol (PEG)

• Polyethylene Glycol (PEG) is another type of GC column that is used for substances with a higher temperature, meaning that it is less susceptible to damage caused by oxygen. it is usually used to study and analyze alcohols, aldehyde and ketones.

Cyanopropylphenyl Polysiloxane (Volatiles)

• The Cyanopropylphenyl Polysiloxane (Volatiles) is a type of GC column that is primarily used for the study and analysis of heavily volatile substances. This type of column is also used for the analysis of alcohols, but is usually used for the study of organic but unstable substances.

Permethylated Beta Cyclodextrin (Chiral)

• The Permethylated Beta Cyclodextrin (Chiral) is used for the non-volatile substances, often the ones that are found in natural products. More specifically, this column is used for the extraction and separation of naturally occurring substances and compounds. These compounds are often called Chiral compounds, meaning that it is a substance that thrives as a standalone compound and is otherwise non-super-imposable.

50 Percent Cyanopropylphenyl Polysiloxane

• The 50 Percent Cyanopropylphenyl Polysiloxane is primarily used for the extraction, septation and study of fatty acid methyl esters as well as neutral sterols and other carbohydrates that are found in both naturally occurring substances and synthetic and man-made substances. It is not a common type of a column, but is still used for specialized analysis.
