From 1994 up to 2004 Synspec also produced Syntech Spectras GC855.
These analyzers are no longer available.

However, all applications serviced by GC855 are available on new machines.
Contact us if you want to know the replacement analyzer.

It is either :

Syntech Spectras GC955:
most likely if you have a preconcentration trap in the analyzer

Synspec Alpha:
if you have M/TNMHC application or an Ethene monitor

Synspec Delta:
if you have an industrial safety monitor, for instance for Ethylene oxide, Vinyl Chloride, Benzene etc.
