You searched for: GC Sorbents

Ready-to-use GC sorbents prepare, measure, and purify sample mixture compounds. When analyte molecules are swept through the column by a gas, molecules separate based on traveling at different rates through the sorbent to the end of the column. Managing water interferences, the sorbent trap method is the most popular among researchers. GC sorbents adapt to any chemical volatile organic compound or use in conjunction with sophisticated automated systems to provide the quickest products.

Packing materials for GC columns, CarboBlack

Supplier: Restek

Graphitized carbon black offers unique selectivity and very little adsorption for alcohol analyses. CarboBlack packings are treated with KOH or picric acid for basic or acidic compounds, and special alcoholic beverage loadings are available. CarboBlack supports provide resolution and retention similar to Carbopack™ and Carbograph supports.

Silylation derivatisation reagents

Supplier: Restek

Silylation is the most widely used derivatisation procedure for sample analysis by GC. In silylation, an active hydrogen is replaced by an alkylsilyl group such as trimethylsilyl (TMS) or tert-butyldimethylsilyl (tert-BDMS). Silyl derivatives are more volatile, less polar, and more thermally stable. As a result, GC separation is improved and detection is enhanced.

Packing material for columns, Res-Sil

Supplier: Restek

These bonded silica packings with n-octane or cyanopropyl (OPN) functional groups yield faster separations of C1 to C4 hydrocarbons, higher thermal stability, shorter conditioning times, and longer lifetimes.

Acylation derivatisation reagents

Supplier: Restek

Acylation reagents offer the same advantage available from silylation reagents: creating less polar, more volatile derivatives. In comparison to silylating reagents, the acylating reagents can more readily target highly polar multifunctional compounds, such as carbohydrates and amino acids. In addition, acylating reagents offer the distinct advantage of introducing electron-capturing groups, thus enhancing detectability during analysis.
