There shall be no major safety accidents and major environmental pollutant incidents in the past three years; ---Production enterprises’ total pollutant control: production enterprises shall be requested to reach the national and local total pollutant discharge control indicators; ---Production enterprises’ management: production enterprises shall be requested to respectively establish and operate environmental management system, analysis equipment may also adopt other equipment other than what is stipulated in HJ/T 400-2007. However, it shall be guaranteed that quantitative relative standard deviation (RSD) within the dynamic range is not more than 10%, and the quantitative repeatability relative standard deviation (RSD) in 5 successive sample injection is not more than 10%. A.3 Sample Sample dimension shall be: 100 mm 100 mm 2 mm. A.4 Handling of Sample Bag Firstly, seal up the sample bag, then, pump out air in the sample bag. Then, fill in the sample bag with pure nitrogen (purity: above 99.99%), which occupies around 50% of its volume. In 60 °C incubator, place it for 2 h. Then, use a vacuum pump to promptly pump out air in the sample bag. A.5 Sealing and Packaging of Sample Sealing and packaging of sample shall comply with the following steps: a) Measure and record the dimensions of sample (mm); b) Inject sample into the sample bag, which is already processed in accordance with the requirements in A.4, then, seal it up; c) Fill in the sample bag with pure nitrogen, which occupies around 30% of the volume of the sample bag, then, use a pump to pump out the air; d) In accordance with c), conduct repeated operation twice, then, at 25 °C, fill in pure nitrogen, which is around 50% of the volume of the sample bag. A.6 Gas Trapping Before conducting gas trapping, place the sample, which is sealed and packed in A.5, into 60 °C incubator for 2 h. Maintain the sample at 60 °C for 2 h, then, in accordance with the tubing demonstrated in Figure A.1 and the following steps, conduct the sampling: a) Lightly rub the sample bag, which is loaded with components, so that the gas inside the bag can be homogenized. Slightly open the valve to squeeze out residual gas in the tube; b) On Conduit 1, install TENAX tube; on Conduit 2, install DNPH tube; c) Open the valve on Conduit 1 and Conduit 2, then, start the sampling; d) After the sampling of TENAX tube on Conduit 1 is completed, close the valve If the analysis cannot be conducted immediately, use aluminum foil to properly pack the trapping tube, then, store it in a cool and dark place (below 10 °C); the storage period shall be 7 d at the maximum. Under the above-mentioned conditions, use DNPH trapping tube to conduct the sampling once. If the analysis cannot be conducted immediately, use aluminum foil to properly pack the trapping tube, then, store it in a cool and dark place (below 10 °C); the storage period shall be 7 d at the maximum. A.7 Analysis A.7.1 Analysis of benzene series Conduct the measurement in accordance with the stipulations in 5.1 in HJ/T 400-2007, namely, thermal desorption/capillary gas chromatography/mass spectrometry. Prepare 2 TENAX for measurement, one of which shall be reserved for later usage. When the first TENAX is adopted in the measurement of benzene series, if quantitative substance exceeds the linear range, highest point of standard solution may be added, or, sampling amount may be reduced, or, the split ratio may be altered for a re- measurement. Conduct parallel sampling (not less than 2 parallel samples), the relative deviation between the measured value and the average value shall not exceed 20%. A.7.2 Analysis of aldehyde ketone Conduct the measurement in accordance with the stipulations in 5.2 in HJ/T 400-2007, namely, solid phase adsorption/high performance liquid chromatography. In the analysis of each batch of samples, at least retain 2 sampling tubes (1 TENAX and 1 DNPH) to conduct gas trapping and analysis of an empty bag (does not seal or pack sample; but contains nitrogen and goes through heating treatment). This shall be considered as on-site blank test during the sampling process. Compare the zero concentration value of the analysis result and the calibration curve. If this turns out to be abnormal, then, this batch of samples shall become invalid. A.8 Data Processing and Test Report A.8.1 Data processing Volatile concentration shall be calculated in accordance with Formula (A.1): Where, C---sample volatile amount, expressed in (μg/m3); W---compound amount measured through trapping tube, expressed in (μg); ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
