1 <br />7.2.15 Compare the analyte concentrations in the 1312 extract with <br />' the levels identified in the appropriate regulations. Refer to Section <br />8.0 for quality assurance requirements. <br />' 7.3 Procedure when Volatiles are Involved <br />Use the ZHE device to obtain 1312 extract for analysis of volatile <br />' compounds only. Extract resulting from the use of the ZHE shall not be used to <br />evaluate the mobility of non-volatile analytes (e•a., metals, pesticides, etc.). <br />The ZHE device has approximately a 500 mL internal capacity. the ZHE can <br />thus accommodate a maximum of 25 grams of solid (defined as that fraction of a <br />sample from which no additional liquid may be forced out by an applied pressure <br />of 50 psi), due to the need to add an amount of extraction fluid equal to 20 <br />times the weight of the solid phase. <br />Charge the ZHE with sample only once and do not open the devices until the <br />final extract (of the solid) has been collected. Repeated filling of the ZHE to <br />obtain 25 grams of solid is not permitted. - <br />Da not allow the sample, the initial liquid phase, or the extract to be <br />exposed to the atmosphere for any more time than is absolutely necessary. Any <br />manipulation of these materials should be done when cold (4'C) to minimize lass <br />of volatiles. <br />' .7.3.1 Pre-weigh the (evacuated) filtrate collection container <br />(see Step 4.6) and set aside. If using a TEOLAR` bag, express alt liquid <br />' from the ZHE device into the bag, whether for the initial or final <br />liquid/solid separation, and take an aliquot from the liquid ~in the bag <br />for analysis. The containers-listed in Step 4.6 are recommend~ad for use <br />' under the conditions stated in Steps 4.6.1-4.6.3. <br />7.3.2 Place the ZHE piston within the body of the ZHE (it may be <br />helpful first to moisten the piston 0-rings slightly with e~xtraetion <br />fluid). Adjust the piston within the ZHE body to a height that will <br />minimize the distance the piston will have to move once the ZHE -s charged <br />with sample (based upon sample size requirements determined from Step 7.3, <br />' Step 7.1.1 and/or 1.1.2). Secure the gas inlet/outlet flange (bottom <br />flange) onto the ZHE body in accordance with the manufacturer's <br />instructions. Secure the glass fiber filter between the support screens <br />' and set aside. Set liquid inlet/outlet flange (top flange) aside. <br />7.3.3 If the sample is 100% solid (see Step 1.1.1), weigh out <br />' a subsample (25 gram maximum) of the waste, record weight, and proceed to <br />Step 7.3.5. <br />1.3.4 If the sample contains <0.5% dry solids (Step 7.1.2), the <br />' liquid portion of waste, after filtration, is defined as the 1312 extract. <br />Filter enough of the sample so that the amount of filtered liquid will <br />support all of the volatile analyses required. For samples containing <br />' >0.5% dry solids (Steps 1.1.1 and/or 7.1.2), use the percent solids <br />information obtained in Step 7,1..1 to determine the optimum sample size to <br />charge into the ZHE. The recommended sample size is as follows: <br />' 1312 - 14 Revision 0 <br />November 1990 <br />
