7 sample extraction

7.1 Extraction pool selection Under normal circumstances, 11 ml of the extraction tank (5.2) can hold 10 g sample, 22 ml extraction tank (5.2) can hold 20 g sample, 34 ml extraction tank (5.2) can be installed 30 g sample (extraction tank specific specifications see the instrument manual). Note 3. The sample weighed depends on the sensitivity of the analytical method used for subsequent use, the purpose of the analysis and the degree of contamination of the sample, the soil or sediment sample should Control in the range of 10 g ~ 30 g. 7.2 Loading of sample Take a clean extraction cell (5.2) to tighten the bottom cover and place it vertically on the horizontal table. Place a dedicated glass fiber filter on the filter Its bottom, the top placed a special funnel. Appropriate amount of sample (6.2) with a small beaker, if you want to add a substitute or isotope internal standard, Should be added to the sample, slightly shaking the small beaker to mix it into the sample. According to the number of samples in turn through the special funnel carefully turn Move to the extraction tank (5.2), remove the funnel, tighten the top cover (avoid sticking the sample to the extraction tank thread or spill). Vertical and smooth Pick up the extraction tank (5.2), tighten the lid at both ends and place it vertically and smoothly into the pressurized fluid extraction unit (5.1) in. Place a clean receiving bottle at the corresponding position of each extraction cell, record the corresponding extraction pool (5.2) for each sample and receive The number of the bottle. Corresponding to the receiving bottle volume, usually the extraction pool volume of 0.5 times to 1.4 times, different instruments will be different. Note 4. The upper end of the extraction cell after loading the sample should be kept at a height of 0.5 cm to 1.0 cm. If the upper space of the extraction cell is larger than 1.0 cm, Add appropriate amount of quartz sand (4.10). 7.3 Selection of solvents The following solvents or mixed solvents are recommended depending on the target. 7.3.1 Organophosphorus pesticides Dichloromethane (4.1); or acetone-dichloromethane mixed solution (4.4). 7.3.2 Organochlorine pesticides Acetone-dichloromethane mixed solution (4.4); or acetone-n-hexane mixed solution (4.5). 7.3.3 Chlorinated Herbicides Acetone - dichloromethane - phosphoric acid solution (4.8). 7.3.4 Polycyclic aromatic hydrocarbons Acetone-n-hexane mixed solution (4.5). 7.3.5 Polychlorinated biphenyls N-hexane (4.2); or acetone-dichloromethane mixed solution (4.4); or acetone-n-hexane mixed solution (4.5). 47.3.6 Other semi-volatile organic compounds Acetone-dichloromethane mixed solution (4.4); or acetone-n-hexane mixed solution (4.5). 7.4 Extraction conditions Carrier pressure. 0.8 MPa; Heating temperature. 100 ℃ (organic phosphorus pesticide can also choose 80 ℃, PCBs can choose 120 ℃); Extraction tank pressure. 1200 psi ~.2000 psi (about 8.3 MPa ~ 13.8 MPa); Preheat balance. 5 min; Static extraction time. 5 min; Solvent elution volume. 60% pool volume; Nitrogen (4.11) Purge time. 60 s (according to the extraction tank volume to increase the purge time in order to thoroughly rinse the sample); Static extraction times. 1 ~ 2 times. The above parameters are optimized for this method, and other reference conditions can also be selected according to the target compound or different instruments. 7.5 Automatic extraction of samples Conditions set, start the program, the instrument automatically complete the extraction. After the extraction is finished, the receiving vials are removed in turn, and the extract is concentrated and purified according to the analytical method. Analysis. 7.6 blank test Take the same mass of quartz sand (4.10) instead of the sample and follow the same procedure as the sample extraction (7.1 to 7.5).

8 Precautions

8.1 The extraction process should be carried out under ventilation conditions. 8.2 Extraction solvents can not be used in the self-ignition point in the range of 40 ℃ ~.200 ℃ extraction solvent (such as carbon disulfide, ether and 1,4- Dioxane, etc.). 8.3 The organic solvent should be degassed before use. The error indication of the organic solvent sensor is subject to troubleshooting, generally As a result of solvent leakage, should be carefully checked whether the sealing pool, or whether the gasket failure. Sometimes due to exposure to The light near the receiving bottle is too strong and the alarm. 8.4 When removing the sample from the extraction cell or cleaning the extraction tank, avoid the scratches on the inner wall of the extraction tank to affect the extraction effect. 8.5 A mixed solution of acetone-dichloromethane-phosphoric acid solution (4.8) was used in the extraction of chlorinated herbicides, using acetone (4.3) Rinse the piping used in the instrument. 8.6 The used extraction tank should be thoroughly cleaned to avoid contamination of the sample and residual sample clogging the extraction tank Stainless steel Sand filter mat. Specific cleaning methods. the extraction pool all open, with hot water, organic solvents (4.1 or 4.2 or 4.3) and the experiment Wash the water in turn with an ultrasonic cleaner. 8.7 All glassware application of washing liquid, tap water followed by washing, with chromic acid lotion soak overnight, and then tap water, the experiment Wash the water in turn, dry, spare, to prevent organic residues. 8.8 When the extraction conditions such as solvent, temperature and pressure are changed, the recovery rate should be re-verified.

9 Waste disposal

The organic waste generated in the experiment and other hazardous waste should be classified and stored, centralized custody, sent to the qualified unit processing.
