Description:Warning: phenolic compounds belong to toxic substances, the sample preparation process should be operated in a fume hood, operating personnel should avoid direct contact with skin and clothing.
This standard stimulates the determination of phenolic compounds in the air of high-performance liquid chromatography (HPLC).
This standard applies to the determination of 12 kinds of phenolic compounds in ambient air (see appendix A) determination of specific components. This standard does not apply to the determination of phenolic compounds in particulate matter.
When the sampling volume of 25 L, this method Detection limit of 0.006 ~ 0.039 mg/m < 3 > superscript, determination of lower limit of 0.024 ~ 0.024 mg/m (superscript 3 >; When the sampling volume for 75 L, the method detection limit is 0.002 ~ 0.013 mg/m < 3 > superscript, determination of lower limit of 0.008 ~ 0.008 mg/m (superscript 3 >.
