Supplier: VWR Chemicals

Diatomaceous silica for filtration.

Supplier: VARIAN

Though highly stabilised, it is impossible to guarantee that no particles will dislodge from the column wall. When used in valve-switching applications, the use of a particle trap can prevent scarring of the rotors.

Supplier: Hach

Reagenzien für extern oder im Labor durchgeführte photometrische Analysen

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.
