| Abstract: | In the monitoring of the air environment,sampling is the first and essential step.Methods of sampling have a bearing on the reliability and accuracy of the result.Therefore,sampling workers must make error analysis before sampling,adjust the sampling equipment regularly,check the airtight of sampling system,adjust flow regularly and grasp the setting of programme.In the end,They must bring the samples back to the lab safely and promptly to analyze. |

| Keywords: | error analysis adjust equipment check airtight constant current sampling adjust flow |
