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.

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.

These septa are suitable for use with 13-425 threaded caps or 13 mm snap/crimp caps.

Supplier: DWK Life Sciences

Silicone, translucent.

Supplier: Agilent

These inlet liners prevent adsorption and ensure accurate sample transfer onto the GC column through a robust deactivated surface. These liners are recommended for trace level analysis of active analytes. Liners with inert wool retain non-volatiles, prolonging column life and lowering frequency of MS source maintenance.

Supplier: Trajan Scientific and Medical

Vespel/graphite GC ferrules are made from quality polyimide/graphite blend. They seal with minimal torque and can be reused and repositioned along capillary columns if not over compressed in the fitting. Due to slight shrinking at high temperatures, they must be retightened after initial temperature cycles to avoid leaks.

Supplier: CHROMACOL
