HH-CO2-50 Capillary column for the determination of trace benzene and ethylene oxide in carbon dioxide for food, acetaldehyde/methanol/vinyl chloride
HH-CO2-50 Capillary column for the determination of trace amounts of benzene and ethylene oxide in carbon dioxide for food, acetaldehyde/methanol/vinyl chloride. Details:
Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a new type of gas chromatograph to analyze common impurities such as methanol, ethylene oxide, acetaldehyde, vinyl chloride, and benzene in food-grade carbon dioxide.
Taking the food additive carbon dioxide as a sample, the chromatographic column box temperature control was optimized, and good fast analysis conditions were established. The retention time of the impurities in the food additive carbon dioxide was determined by the external standard method.
Under the established analytical method and the best experimental conditions, the relative standard uncertainty of ethylene oxide, acetaldehyde, vinyl chloride and benzene was measured at one time, and the relative standard uncertainty was within 3%. The correlation coefficient is greater than 0.999 5, and the detection time is shortened to nearly one third of that of the national biao regulations.
The relative standard deviation of the measurement results is less than 3%, and the relative error from the standard value is less than 2%. The established analysis methods and conditions have more precise and simple analysis characteristics, and also greatly save the cost of testing and instrument maintenance, and improve work efficiency. This method is suitable for the analysis and detection of impurities in food-grade additive carbon dioxide.
The potential of this capillary column: It can analyze acetaldehyde, methanol, ethylene oxide, vinyl chloride and trace amounts of benzene in one injection.
