氨氣中的氨純度測定專用填充柱
氨氣中的氨純度測定專用填充柱 詳細(xì)信息：


名稱：填充柱
固定相：專用
規(guī)格：2m*1/8
型號：HH-NH3
應(yīng)用：工業(yè)氨水及氣氨的色譜測定


氣氨純度的測定采用傳統(tǒng)的吸收測定法,此方法操作繁瑣,分析時間長,樣品用量多,而且測定結(jié)果受人為因素影響較大,如吸收時氣體流速的大小,液位讀數(shù)的偏差及標(biāo)準(zhǔn)溶液滴定、終點(diǎn)判斷等都會對測定結(jié)果造成較大的誤差,而且吸收管有時密封不嚴(yán)出現(xiàn)倒吸現(xiàn)象,導(dǎo)致分析失敗或結(jié)果不準(zhǔn)確。

現(xiàn)改用氣相色譜法測定氨氣中氨純度的分析方法,浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司用HH-NH3氨專用填充色譜柱對樣品進(jìn)行分離,用熱導(dǎo)檢測器檢測分離物,用外標(biāo)法作定量計(jì)算,測定結(jié)果的大相對標(biāo)準(zhǔn)偏差為0.2%。該方法分析速度快、操作簡單,重復(fù)性好,準(zhǔn)確度高。可以滿足生產(chǎn)要求,還可降低員工的人身傷害。

此柱柱效高，分離好，氨峰型對稱，結(jié)果滿意。此柱為浩瀚色譜，的產(chǎn)品。

Special packed column for determination of ammonia purity in ammonia gas
Packed column for the determination of ammonia purity in ammonia gas Details:

The determination of the purity of gas ammonia adopts the traditional absorption measurement method, which is cumbersome to operate, takes a long time to analyze, requires a lot of samples, and the measurement results are greatly affected by human factors, such as the size of the gas flow rate during absorption, the deviation and standard of the liquid level reading. Solution titration, end point judgment, etc. will cause large errors in the measurement results, and sometimes the absorption tube is not tightly sealed and sucks back, resulting in analysis failure or inaccurate results.

Now use gas chromatography to determine the analysis method of ammonia purity in ammonia gas. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses HH-NH3 ammonia special packed chromatographic column to separate the sample, and the thermal conductivity detector is used to detect the separated substance. The external standard method was used for quantitative calculation, and the maximum relative standard deviation of the determination results was 0.2%. The method has the advantages of fast analysis speed, simple operation, good repeatability and high accuracy. It can meet the production requirements and reduce the personal injury of employees.

This column has high column efficiency, good separation, symmetrical ammonia peaks, and satisfactory results. This column is a unique product of the vast chromatography.
