Quantitative Analysis of Hydrogen Sulfide in Beer Using Nexis™ SCD-2030

User Benefits

- A state-of-the-art sulfur chemiluminescence detector (SCD) enables highly sensitive analysis of sulfur components. - Quality control with higher accuracy is realized by monitoring hydrogen sulfide in beer. - Use of a headspace sampler eliminates the need for sample preparation in analysis of samples.

Introduction

When brewing beer, various volatile sulfur compounds are formed in the yeast fermentation process. Hydrogen sulfide (H₂S) is one sulfur compound that has a particularly strong effect on the flavor of beer and is one off-flavor that should be removed as far as possible, depending on the product. Thus, quantitation of hydrogen sulfide in beer is a crucial element for control of beer quality and the beer manufacturing process. The sulfur chemiluminescence detector (SCD) Is capable of detecting selectively sulfur compounds with high sensitivity. Use of an SCD in combination with the headspace (HS) method makes it possible to analyze volatile sulfur compounds in beverages. In this article, the hydrogen sulfide contents of several commercial beer products were measured and quantified by using an SCD and HS.
