3-in-1 Beer Analyzer Shimadzu GC-2014 with HS-10 headspace autosampler Quantitative analysis of beer volatile organic compounds, ethanol and diacetyls following the ASBC method Beer-4, -25 and -48 Dual column simultaneous analyses with one sample injection

The chemistry of beer brewing is quite complex. This Shimadzu 3-in-1 beer analyzer is a cost-effective solution for craft beer breweries that wish to monitor the quality of their products through GC analysis of certain well-established measurable parameters, specifi cally the concentrations of the volatile organic compounds (fl avor compounds), the diacetyls (the unwanted buttery fl avor) and the ethanol content.

3-in-1 Beer Analyzer Set-up• A 2-way injection port adaptor allows easy splitting of one sample into two analytical columns• Column 1 (Shimadzu SH-Stabilwax) is attached to FID for analysis of volatiles and ethanol content• Column 2 (Shimadzu SH-Rxi-5SilMS) is attached to ECD for analysis of diacetyls
