四氟化硫測定專用填充色譜柱
四氟化硫測定專用填充色譜柱 詳細(xì)信息：

名稱：填充柱

規(guī)格：6m*3mm，6m*1/8

型號：HH-SF4

應(yīng)用：四氟化硫及雜質(zhì)測定 氣相色譜法

四氟化硫的生產(chǎn)工藝，屬于氟化工領(lǐng)域。工藝包括氟氣純化、五氟化碘的制備、四氟化硫反應(yīng)合成、四氟化硫分離和捕集、四氟化硫精餾與罐裝、五氟化碘二次回收和尾氣排放。電解氟通過低溫冷凝裝置純化氟氣，除去大量氟化氫氣體，提高了氟氣濃度，冷凝回收裝置回收碘、五氟化碘，循環(huán)使用，碘的利用率可提高70%以上，減少原料損失，連續(xù)精餾的方法使四氟化硫產(chǎn)品純度可達(dá)99.9%以上，產(chǎn)品常溫充入鋼瓶更加安全。另外，合成四氟化硫工藝生產(chǎn)全程采用DCS自動化裝置控制，減少人為隨意性、經(jīng)驗性，提高產(chǎn)品質(zhì)量的穩(wěn)定性。

Packed chromatographic column for sulfur tetrafluoride determination
Packed chromatographic column for sulfur tetrafluoride determination Details:

Name: Packed column

Specification: 6m*3mm, 6m*1/8

Model: HH-SF4

Application: Determination of Sulfur Tetrafluoride and Impurities Gas Chromatography

The production process of sulfur tetrafluoride belongs to the field of fluorine chemicals. The process includes the purification of fluorine gas, the preparation of iodine pentafluoride, the reaction synthesis of sulfur tetrafluoride, the separation and capture of sulfur tetrafluoride, the distillation and canning of sulfur tetrafluoride, the secondary recovery of iodine pentafluoride and the discharge of tail gas. Electrolysis of fluorine purifies fluorine gas through a low-temperature condensation device to remove a large amount of hydrogen fluoride gas, which increases the concentration of fluorine gas. The condensation recovery device recovers iodine and iodine pentafluoride, and is recycled. The utilization rate of iodine can be increased by more than 70%, reducing raw material loss, and continuous The method of rectification makes the purity of the sulfur tetrafluoride product more than 99.9%, and it is safer to fill the product into a steel cylinder at room temperature. In addition, the whole process of synthetic sulphur tetrafluoride production is controlled by DCS automation equipment, which reduces human arbitrariness and experience, and improves the stability of product quality.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses gas chromatography to analyze the content of each component of sulfur tetrafluoride. The method is: pretreatment of the sample, separation by a special packed column, detection with TCD detector, and quantitative calculation with normalization method. It has been verified that the method is simple and reliable, and the results are accurate. It has been recognized and recognized by relevant international partners.
