Determination of methanol content in methanol gasoline for vehicles Porapak T packed column
Detailed information of Porapak T packed column for determination method of methanol content in methanol gasoline for vehicles:
Name: Filled column
Model: Porapak T
Specification: 1m * 1/8, 60-80 meshes
Operating temperature: 190 ° C
No.: 20221211003
Application: Determination of methanol content in methanol gasoline for vehicles
This standard specifies the terms and definitions, principles, instruments, reagents and materials, sampling, test procedures, result calculation and allowable deviation of the detection method for methanol content in methanol gasoline for vehicles.
This standard is applicable to the determination of methanol content (volume fraction) in methanol gasoline for vehicles without ethanol.
Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. combined the distilled water extraction method with gas chromatography analysis technology to analyze and determine the methanol content in different specifications of methanol gasoline for vehicles. The effects of extraction time, extraction times and additives on the determination results were investigated The results showed that in the whole extraction process, shaking for 4 min, standing for 6 min, and extracting once could achieve good extraction effect The method has good precision and the recovery is between 98% and 103%
