It uses a carrier gas to transport the injected sample through an expansion bulb into the ion source via a length of deactivated column. There are no glass valves, no sample freezing to pump out air and no sample pump out after analysis. Typical sample injection size is in tenths of microliters, and in some cases may be less. The DBI bolts directly onto existing hardware in most cases. In any event, GBS can supply a complete bolt-on system to suit any specifications.
Installation is very straight forward.
