Shimadzu HS-20 headspace sampler

Shimadzu Corporation has launched the HS-20 gas chromatography headspace sampler for the accurate analysis of a wide range of volatile compounds by both GC and GCMS. The configuration of the HS-20 flow lines and oven enable the analysis of high boiling point compounds while minimising carryover. As the trap function incorporates an electronic cooling mechanism, it is also possible to concentrate the headspace gas, which enables high-sensitivity analysis of low to high boiling point compounds.

The deactivated sample flow lines and flow line structure minimises sample adsorption, achieving an extremely low carryover under 0.0001% even for highly adsorptive acetic acid. The oven can be set to 300°C, enabling the analysis of high boiling point compounds - normally difficult with conventional headspace samplers. The short (30 cm) transfer line means that even high boiling point components such as phthalate esters or cyclic siloxanes can be efficiently analysed.

The trap version concentrates the headspace gas to allow high-sensitivity analysis of volatile compounds generated from the sample. Cooling the trap to -20°C using the electronic cooling function efficiently concentrates low boiling point components in the trap. Consequently, components with a wide range of boiling points can be analysed with high sensitivity and accurate quantitation of trace components.
