2 The apparatus consists of a cylindrical sample chamber supported on both ends by plates. Tie rods connect the end plates. Viton -A 0-rings seal the contents of the cylinder. Pressure moves a dual sealed piston within the honed cylinder. A series of valves allows the induction or release of pressure and the subsequent movement of the piston, sample or extraction fluid as required. Etched screens held just beneath the plug valve provide support for a 90 mm filter through which the TCLP extract must of the solid fraction of the sample takes place in a rotary extractor with the ZHE+ zero headspace extractor being tumbled end over end for eighteen hours at 30 rpm. The Heavy-Duty LE Rotator from Environmental Express (Catalog # LE1002, LE1002-240) is suitable and meets the requirements of Method 1311.

The ZHE+ unit comes fully assembled and includes a set of spare O-rings and a polyethylene tool to remove the piston from the sample cylinder. Inspect all parts upon receipt: if any damages or shortages are suspected, call Environmental Express immediately at Wet the piston with reagent-grade water and position it inside the honed sample barrel at the appropriate height. (Initially the barrel should hold the entire sample with as little headspace as is reasonable to begin work. The sample will be in the stepped end of the barrel, not the grooved end.)

6 3. Wet both plate O-rings with reagent-grade water and place one in each end plate O-ring With the toggle valve open, set the sample barrel into the bottom plate, grooved end Pour in the Center a 90 mm, m glass fi ber fi lter (Catalog # FG75090MM or FG77090MM) between the two photo-etched screens. Insert this fi lter sandwich in the top plate, and place the large cylinder O-ring against the sandwich to lightly hold it in With the plug valve open, place the top plate onto the cylinder. Make sure that the cylinder O-ring is seated evenly, and then secure the unit tightly with the hand Close the plug valve down until only a relief crack can be seen inside the valve, and connect the male/female quick : Before pressurizing to clear headspace , make sure that only a small crack is left open inside the plug valve.

7 This will reduce the risk of accidentally shooting liquid sample or extraction fl uid out of the ZHE+ : Do not pressurize beyond the top operating pressure of 50 Slowly pressurize to clear headspace according to method For liquid and multi-phasic samples, shut off the plug valve after the TCLP extract has been expressed and, if necessary, introduce the proper extraction fl uid. After clearing headspace again, your multi-phasic sample is ready for rotary For solid samples, when pressure reaches 20 psi on the gauge, end pressurization and open the vent relief valve to release pressure (leave vent relief valve open). Load the required amount of extraction fl uid into the ZHE+ unit through the opened plug valve. Close the vent relief valve and pressurize to clear headspace .

8 As soon as extraction fl uid appears, shut off the plug valve and end pressurization. Your solid sample is now ready for rotary To remove the TCLP extract, attach either a Tedlar bag (Catalog # TB7000GD or TB2000-10) or an acceptable gas-tight syringe (Catalog # S1005, S1010, S1025, S1050, or S1100) to the plug valve, open the plug valve, and with Rotary ExtractorsIf you have purchased the Heavy-Duty LE Rotator (Catalog # LE1002 or LE1002-240) from Environmental Express, you will need either Extractor Pad Set (Catalog # LE1603) or suffi cient packing materials to insure the immobility of the ZHE+ unit while rotating. If you have manufactured your own box-type rotary extractor, place suffi cient packing materials around the ZHE+ unit to insure immobility while 28/3/2016 4:05:08 PMZHE+ Zero headspace Extractor: Operation and Instruction Manual Maintenance and Warranty / / Environmental Express 4 Product Information.

Your serial # is located on the back of the 800-343-5319 or 843-881-6560 2345 A Charleston Regional Pkwy Charleston, SC 29492 Maintenance and CareThe ZHE+ zero headspace extractor should be thoroughly cleaned and inspected before each use. A non-abrasive laboratory cleanser such as Alconox or Sparkleen is suitable.

10 Do not use steel wool or abrasives such as Comet . It should be rinsed with laboratory-grade water. All O-rings should be inspected for signs of wear before each use, and frequent replacement of O-rings (Catalog # ZVR1000), along with the rings within the plug valve (Catalog # ZVR9903), is recommended to reduce both sample and blank contamination. Note: 316 grade stainless steel is a hard, inert metal, but possible to damage. Avoid rough handling and overexposure to a leak test on the ZHE+ unit should be performed to ensure proper Operation . To perform a leak test, fully assemble the unit and pressurize to 50 psi. Leave pressurized for an hour and check the gauge for any pressure loss. If a pressure loss is found, re-pressurize the unit, place under water and look for bubbles.
