Test mixture 2 for apolar capillary columns according to Grob, Supelco®, for GC, ready-to-use, : N/A

Supplier: Merck

Inlet liners used in an GC require an O-ring placed near the top for proper operation. This O-ring ensures that the only path for carrier gas to get to the outside of the inlet liner is through the grooves in the inlet seal at the bottom of the injection port.

Supplier: Merck

These are ionic liquid GC columns. They offer a great choice for analysis of neutral and polarisable (contain double and/or triple C-C bonds) analytes.

Supplier: Merck

These non-polar methyl silicone bonded poly(dimethyl siloxane) columns are used to separate the sample components according to boiling point.

Supplier: Merck

These bonded poly(5% diphenyl/95% dimethylsiloxane) low phenyl content columns improve thermal stability of the phase, while still providing essentially a boiling point elution order, and a slight increase in selectivity, especially for aromatic compounds.

Supplier: Merck

This non-polar column is specially designed for reproducible analyses of plant sterols, cholesterol, and other animal sterols.

Supplier: Merck

These bonded SUPELCOWAX® 10 columns are widely used for separation and purity analyses of many polar compounds, including alcohols, aromatics, and other solvents, flavors, fragrances and FAMEs.

Supplier: Merck

This intermediate polarity column is mainly designed for analyses of volatile organic compounds (VOCs), offers great retention and resolution of highly volatile compounds.

Supplier: Merck

This column with bonded poly(ethylene glycol) phase allows highly reproducible analyses of fatty acid methyl esters (FAMEs), specifically the omega 3 and omega 6 fatty acids. It is tested to ensure reproducible FAME equivalent chain length (ECL) values and resolution of key components.

Supplier: Merck

Specially prepared and tested columns to seperate geometrical position (cis/trans) isomers of fatty acid methyl esters. Seperation of FAMEs should be take place in hydrogenated vegetable oil samples.

Supplier: Merck

These columns are situated between the traditional non bonded cyanosilicone phases SP-2330 and SP-2340 in polarity. The high polarity of this phase allows the separation of geometric (cis/trans) fatty acid methyl ester isomers as a group.

Supplier: Merck

This column provides boiling point elution order with a slight increase in selectivity, especially for aromatic compounds.

Supplier: Merck

This column is specially designed for purge-and-trap analyses of volatile halogenated, non-halogenated, and aromatic contaminants from environmental samples.

Supplier: Merck

Reference substances can be used for the identification of unknown compounds in a gas chromatogram or as standards in quantitative GC analysis. They serve also for the characterisation of GC column properties.

Wool plugs are often used in GC inlet liners to improve sample vaporization, and/or to keep non-volatile material from entering the column. They can also be used in packed GC columns, solvent desorption tubes, thermal desorption tubes, and purge traps to retain packed beds.
