GB/T 685-2013 化学试剂 甲醛溶液
本标准于2014年8月1日起代替GB/T 685-1993 化学试剂 甲醛溶液。
本标准规定了化学试剂甲醛溶液的性状、规格、试验、检验规则和包装及标志。
本标准适用于化学试剂甲醛溶液的检验。


国标中规定化学试剂 甲醛溶液采用理化滴定法测定，操作复杂，分析时间长，费时费力，不环保，无法满足工业大规模生产检测的需要，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
