| titleOfInvention | A kind of method using gas Chromatographic Determination synthetic grease active ingredient |
| abstract | The invention discloses a kind of method using gas Chromatographic Determination synthetic grease active ingredient, comprise the following steps：S1：Additive is extracted using petroleum ether or chromatogram methanol, obtains additive inspection liquid；S2：The parameter of regulation optimization gas-chromatography, liquid quantitative sample injection is examined by above-mentioned additive, is carried out gas phase spectrum analysis detection, is established the chromatogram of additive inspection liquid, obtain the chromatographic peak retention time scope of additive, establish the chromatogram group of additive inspection liquid；S3：Extraction is diluted to sample using organic solvents such as petroleum ether or alkane, obtains sample inspection liquid；S4：The parameter of gas-chromatography is kept, above-mentioned sample is examined into liquid quantitative sample injection, carries out gas phase spectrum analysis detection, establishes the gas chromatogram of sample inspection liquid；S5：Analysis and the gas chromatogram for calculating sample inspection liquid, determine the content of active ingredient in sample.Each composition accounting of synthetic grease can be analyzed easily by this kind of method, testing result is accurate, time-saving and efficiency. |
