Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses phosphoric acid as the solvent and uses a new device to dissolve mineral rock samples and determine carbon dioxide by gas chromatography. The relative errors of carbon dioxide in the measured carbonate standard samples and silicate standard samples were 0.2% and -47%, respectively; the relative standard deviations were 1.0% and 3.3%, respectively. This method is simple and fast, not only suitable for the determination of low-content carbon dioxide in mineral rocks, but also for the determination of high-content carbon dioxide.

Stationary phase: silica gel

Specification: 2m*3mm

Granularity: 60-80 mesh
