High-Sensitivity Analysis of Fragrance Components by Trap Mode of HS-20 Trap Headspace Sampler

User Benefits

- The trap mode enables analysis of trace components which were undetectable with conventional headspace samplers. - With the HS-20 Trap, concentration of the headspace gas and high-sensitivity analysis are possible with simple setting and operation.

Introduction

Headspace samplers enable high-sensitivity analysis of volatile components by holding the sample injected into the vial under time/temperature-controlled conditions and introducing the gas phase (headspace gas) into a gas chromatograph (GC). In the trap mode of Shimadzu HS-20 Trap headspace sampler, it is possible to concentrate the headspace gas and analyze ultra- trace components that had been impossible to analyze with conventional headspace samplers. In this article, the sensitivity of ordinary headspace analysis (loop mode) and the trap mode was compared by analyzing the fragrance components in a liquid food sample.
