| titleOfInvention | A kind of method measuring chloromethyl methyl ether in materials used in auto manufacturing |
| abstract | The invention belongs to technical field of analytical chemistry, specifically a kind of method measuring chloromethyl methyl ether content in materials used in auto manufacturing, its determination step is, 1) testing sample is cut into the small cubes of size about 2 millimeters × 2 millimeters × 2 millimeters, seals stand-by; 2) take a certain amount of sample in ml headspace bottle, add acetone, then add deuterated toluene as interior mark, cover tightly bottle cap and to be placed in head-space sampler 3) adopt the content of chloromethyl methyl ether in gas chromatograph-mass spectrometer working sample.The present invention adopts headspace sampling technology, gas chromatograph-mass spectrometer measures the content of chloromethyl methyl ether in materials used in auto manufacturing, inner mark method ration, assay method sampling amount is few, pre-treatment is simple to operate, test is quick, and can realize the Accurate Determining of chloromethyl methyl ether in materials used in auto manufacturing, and detecting of the method is limited to 100mg/kg. |
