Highly sensitive analysis of sulfur compounds in beer using the Trap mode of a headspace sampler

User Benefits

- Using the Trap mode of HS-20 NX allows for a simple and highly sensitive analysis of concentrated headspace gas. - By utilizing the Trap mode and SCD-2030, it becomes possible to detect trace sulfur compounds that were difficult to analyze in the Loop mode. - This system is compatible with N2 carrier gas, allowing analysis to be conducted without the use of helium.

Introduction

Volatile sulfur compounds, which are generated during the fermentation process of beer yeast, significantly contribute to the flavor and quality of beer. However, as these compounds exist in very small amounts, their detection requires pre- concentration techniques or the use of high-sensitivity detectors. In a previous Application News titled “Analysis of Volatile Sulfur Compounds in Beer Using Nexis™ SCD-2030”, we introduced an analysis method combining SCD (Sulfur Chemiluminescence Detector) and the Loop mode of the headspace sampler for the analysis of volatile sulfur compounds in beer. In this Application News, we will present the results of further investigation into achieving higher sensitivity using the Trap mode of the headspace sampler.
