Purification device for pharmacopoeia carbon dioxide measurement
Purification device for determination of carbon dioxide in Pharmacopoeia Details:

Name: CO2 purification device

Model: HHO-III Purification device

Application: Determination of Hydrocarbons in Carbon Dioxide in Chinese Pharmacopoeia 2010/2015



The method for the hydrocarbons in carbon dioxide in Part Four of the 2015 Pharmacopoeia is described as follows: "Take this product as the test sample; take a gas with a methane content of 0.0020% (with nitrogen as a diluent) as a reference gas, according to gas chromatography (General Principle 0521) For the test, use a chromatographic column (0.8mX4mm, 80 mesh) filled with glass balls; the column temperature is 110°C; the inlet temperature is 110°C; the detector temperature is 120°C. Measure the sample gas and The control gas is injected into the gas chromatograph, and the peak area measured when the purification temperature is 360°C is the corresponding blank value; the test gas and the control gas are measured and injected into the gas chromatograph to determine the peak area and subtract the corresponding blank value The peak area after that is the calibrated peak area. Calculated with the calibrated peak area according to the external standard method, the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
The pharmacopoeia stipulates that the purification device should be used. However, what bothers the laboratory personnel of the majority of pharmaceutical companies is how to purchase the purification device and how to connect to the gas chromatography. It is powerless. Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps up Guided by the scientific concept of development, the world’s top chromatographic technology is adopted, and the MIT has jointly developed a special purification device for pharmacopoeia carbon dioxide, which has good purification effect and accurate and reliable analysis.

Haohan Chromatography provides a complete analysis plan and installation drawings.
