| titleOfInvention | A kind of detection method of benzene series in workplace |
| abstract | The invention provides a method for detecting benzene series compounds in a workplace, comprising the following steps: (1) loading an activated carbon sampling tube into a sampling device for sampling; (2) loading the activated carbon sampling tube into a storage sleeve for storage and transportation; (3) Draw the standard curve with the mixed standard gas, and calculate the slope of the regression line, and use the inverse of the slope as the calculation factor B of the sample measurement; (4) Connect the sampled activated carbon sampling tube with a 100ml syringe, and place it on the thermal desorption device , and then desorb with nitrogen gas to form a desorbed gas, and take 1ml of the desorbed gas into the chromatographic column, use the retention time for qualitative determination, and the peak height for quantitative determination. Repeat three times for each sample; (5) Calculate the concentration of benzene series in the air. According to the characteristics of Bernoulli's law that the pressure is small in places where the fluid velocity is fast, the sampled gas is blown into the organic solvent to dissolve the residual benzene series, so as to achieve the purpose of purifying the gas, and is environmentally friendly. The advantages. |
