白酒分析專用填充色譜柱
白酒分析專用填充色譜柱 詳細(xì)信息：

名稱：白酒專用填充柱
固定相：DNP+tw-80/CHROMOSORB W AW DMCS
規(guī)格：2m*3mm
應(yīng)用：白酒13組分分析測(cè)定

１．應(yīng)選擇性能好的色譜柱,甲醇與乙醇、乙醇與乙酸乙酯,乙酸乙酯與異戊醇應(yīng)是獨(dú)立而不重疊的色譜峰,沒(méi)有嚴(yán)重拖尾現(xiàn)象。２．定性與定量分析,可從３個(gè)方面調(diào)整:一是調(diào)節(jié)流速,使出峰時(shí)間與原保留時(shí)間一致;二是根據(jù)出峰時(shí)間重新設(shè)立ＩＤ文件。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司應(yīng)用DNP填充柱氣相色譜儀分析清香型白酒,在設(shè)定的條件下,能定性定量分析酒中十余種微量成分,各組分分離較好,分離效能較高.對(duì)進(jìn)樣速度、氣體流速、(檢測(cè)器)FID檢測(cè)溫度、DNP柱效、校正因子等因素進(jìn)行合理調(diào)節(jié)控制,可減少色譜分析誤差,提高測(cè)定組分?jǐn)?shù)據(jù)的準(zhǔn)確性.

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.
