Gas filters
Gas filters are an essential part of GC analysis as contaminants in gases can significantly impact the quality of results. Oxygen, hydrocarbons and moisture can lead to problems such as noisy baselines, moisture entering the GC column and excessive bleed. The gas filter kit consists of a gas filter and a connection unit.Fast stabilization timesThe gas filter system consists of two key parts: the filters and the connecting unitThe connecting unit has inlet and outlet connectors for the gas linesThe connecting unit can be bench or wall-mountedCan be used in combination with other filtersIndicator color change tells you when to change your filter

GC Capillary columns HYDRODEX β-TBDAC
HYDRODEX cyclodextrin phases for enantiomer separationHeptakis-(2,3-di-O-acetyl-6-O-t-butyldimethyl-silyl)-β-cyclodextrin. Phase diluted with optimised polysiloxane recommended for alcohols, esters, ketones, aldehydes, δ-lactones.Max. temperature for isothermal operation: 220 °CMax. temperature for short isotherms in a temperature programme: 240 °C
GC Capillary columns LIPODEX® E
LIPODEX® cyclodextrin phase for enantiomer separationBase material: cyclic oligosaccharide consisting of eight glucose units bonded through α-1,4-linkages (y-cylodextrin) regioselective alkylation and acylation of the hydroxyl groups leads to a lipophilic phase, which is well suited for GC enantiomer analyses; important advantage: many compounds can be analysed without derivatisation (however, for certain substances enantioselectivity can be favourably influenced by formation of derivatives).Octakis-(2,6-di-O-pentyl-3-O-butyryl)-γ-cyclodextrin. Recommended for α-amino acids, α- and β-hydroxycarboxylic acid esters, alcohols (TFA), diols (TFA), ketones, pheromones (cyclic acetals), amines, alkyl halides, lactones.Max. temperature for isothermal operation: 200 °CMax. temperature for short isotherms in a temperature programme: 220 °C
