2020 Pharmacopoeia Carbon Dioxide Glass Spherical Column
2020 Pharmacopoeia Carbon Dioxide Glass Spherical Column Details:

Hydrocarbons are measured by gas chromatography (general rule 0521) and the gas of the test product is taken from this product, that is, the gas with a methane content of 0.0020% is obtained as the reference gas (with nitrogen as the diluent). Chromatographic conditions: Use a chromatographic column (4mm × 0.8m, 80 mesh) with glass balls as filler; the column temperature is 110°C; the inlet temperature is 110°C; the detector is a flame ionization detector, and the temperature is 120°C. Measure the test gas and the reference gas, inject them into the gas chromatograph respectively, and the peak area measured when the purification temperature is 360 °C is the corresponding blank value; accurately measure the test gas and the reference gas, and inject them into the gas chromatograph respectively. Instrument, measure the peak area, and the peak area after subtracting the corresponding blank value is the calibration peak area limit. Calculate the calibration peak area according to the external standard method, and the hydrocarbon content (in terms of methane) shall not exceed 0.0020%.

The above are the index requirements and gas chromatographic determination of hydrocarbons in Pharmacopoeia carbon dioxide in 2020. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts new technology to develop glass sphere chromatography columns for carbon dioxide analysis in Pharmacopoeia in 2020. Tested on the chromatograph, the effect is good, and it is well received by users.

Huohan Chromatography, provide detailed analysis plan, provide purification device, standard gas
