In this application note you will find out how Shimadzu Nexis™ SCD-2030’s redox cell gives higher speed and sensitivity for the analysis of sulfur compounds. In addition you will learn how to determine trace levels of sulfur compounds in various beers.
How to identify a good beer? One such technique to assess its quality is through the determination of sulfur compounds in beer. Trace levels of dimethyl sulfide (DMS), dimethyl disulfide (DMDS) and other sulfur compounds can significantly affect the aroma, flavor and quality of beer. The formation of off-flavor may also occur. Therefore, the monitoring of sulfur compounds during beer production and quality control is critical for beer brewers.
NexisTM SCD-2030 + HS-20
Sulfur Chemiluminescence Detector (SCD) is commonly employed for the quantitation of sulfur compounds. Apart from offering minimal sample preparation using crude samples, an accurate high-sensitivity analysis of sulfur compounds can be achieved using Shimadzu’s latest Nexis™ SCD-2030 detector. This improved detector features a redox cell in a horizontal position with shorter flow path, thereby allowing higher analysis speed and signal-to-noise ratio for trace-level analysis of sulfur compounds.
