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 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.

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.

PL-Wang is a 4-alkoxybenzylalcohol functionalised polystyrene, prepared from copolymerised PL-CMS, for solid phase peptide synthesis using Fmoc protection strategies and is cleaved using ~ 95% TFA. Particularly useful for solid phase synthesis of small molecules which have a carboxylic acid functional group.

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.
