HI-5 MS Phase

One of the most widely used GC phases. This gives all the benefits of the HI-5 phase but with the added benefit of low bleed for improved MS sensitivity.

Standard 5% Phenyl phase on 95% methyl polysiloxane.

HI-1 MS Phase

A widely used GC phase for low polarity or a polar compounds. Gives all the benefits of the HI-5 phase but with the added benefit of low bleeding for improved MS sensitivity.

Standard 100% methyl polysiloxane low bleed phase

HI-WAX HT

Extended temperature range which allows the GC user to analyse heavier compounds. The HI-WAX is for the separation of polar compounds using Mass Spec detection.

Polyethylene glycol (PEG) is a highly polar, cross bonded phase.
