化學試劑 甲醛溶液的色譜測定 詳細信息：

GB/T 685-2013 化學試劑 甲醛溶液
本標準于2014年8月1日起代替GB/T 685-1993 化學試劑 甲醛溶液。
本標準規定了化學試劑甲醛溶液的性狀、規格、試驗、檢驗規則和包裝及標志。
本標準適用于化學試劑甲醛溶液的檢驗。


國標中規定化學試劑 甲醛溶液采用理化滴定法測定，操作復雜，分析時間長，費時費力，不環保，無法滿足工業大規模生產檢測的需要，使用受限。

Chemical reagent Chromatographic determination of formaldehyde solution
Chemical reagent Chromatographic determination of formaldehyde solution Details:

GB/T 685-2013 chemical reagent formaldehyde solution
This standard will replace GB/T 685-1993 chemical reagent formaldehyde solution on August 1, 2014.
This standard specifies the properties, specifications, tests, inspection rules, packaging and marking of the chemical reagent formaldehyde solution.
This standard applies to the inspection of chemical reagent formaldehyde solution.


The national standard stipulates that the chemical reagents and formaldehyde solutions are determined by physical and chemical titration. The operation is complicated, the analysis time is long, time-consuming and laborious, not environmentally friendly, and cannot meet the needs of industrial large-scale production testing and is limited in use.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times and develops gas chromatography to determine the chemical reagent formaldehyde solution. The HH-CH2O2021 high-efficiency column is used to separate methanol, moisture, and formaldehyde. Satisfactory results can be achieved.

This column is a Haohan chromatogram, using a high-efficiency stationary phase developed by new technology, with strong water resistance and long life. Welcome to consult and negotiate.


Name: Packed column
Stationary phase: dedicated
Specification: 2m*3mm
Model: HH-CH2O2021
Application: GB/T 685-2013 chemical reagent formaldehyde solution
