DNP+吐温60 白酒分析专用填充色谱柱的详细资料

白酒分析专用填充色谱柱
白酒分析专用填充色谱柱 详细信息：

名称：白酒专用填充柱
固定相：DNP+tw-80/CHROMOSORB W AW DMCS
规格：2m*3mm
应用：白酒13组分分析测定

１．应选择性能好的色谱柱,甲醇与乙醇、乙醇与乙酸乙酯,乙酸乙酯与异戊醇应是独立而不重叠的色谱峰,没有严重拖尾现象。２．定性与定量分析,可从３个方面调整:一是调节流速,使出峰时间与原保留时间一致;二是根据出峰时间重新设立ＩＤ文件。

浩瀚色谱（山东）应用技术开发有限公司应用DNP填充柱气相色谱仪分析清香型白酒,在设定的条件下,能定性定量分析酒中十余种微量成分,各组分分离较好,分离效能较高.对进样速度、气体流速、(检测器)FID检测温度、DNP柱效、校正因子等因素进行合理调节控制,可减少色谱分析误差,提高测定组分数据的准确性.

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.
