Packed Chromatographic Column for Liquor Analysis
Packed Chromatographic Columns for Liquor Analysis Details:

Name: Packed column special for liquor
Stationary phase: DNP+tw-80/CHROMOSORB W AW DMCS
Specification: 2m*3mm
Application: Analysis and determination of 13 components of liquor

1. Chromatographic columns with good performance should be selected. Methanol and ethanol, ethanol and ethyl acetate, ethyl acetate and isoamyl alcohol should be independent and not overlapping chromatographic peaks, without serious tailing. 2. Qualitative and quantitative analysis can be adjusted from three aspects: one is to adjust the flow rate so that the peak time is consistent with the original retention time; the other is to re-establish the ID file according to the peak time.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses DNP packed column gas chromatograph to analyze fragrant liquor. Under the set conditions, it can qualitatively and quantitatively analyze more than ten kinds of trace components in the liquor. The separation of each component is good, and the separation efficiency is good. Higher. Reasonable adjustment and control of the sampling speed, gas flow rate, (detector) FID detection temperature, DNP column efficiency, correction factor and other factors can reduce chromatographic analysis errors and improve the accuracy of the measured component data.
