Congratulations on the purchase of your ZHE+ Zero Headspace Extractor from Environmental Express

The volatiles section of the TCLP procedure, Method 1311, allows for the collection of leachable volatile organic compounds that may be present in a hazardous waste sample.

The ZHE+ zero headspace extractor meets all EPA criteria for a zero-head space extraction vessel. 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 exit.

Extraction 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.

Note: Inspect all parts upon receipt! If any damages or shortages are suspected, call Environmental Express immediately at 800-343-5319.

Note: 316 grade stainless steel is a hard, inert metal, but possible to damage. Avoid rough handling and overexposure to corrosives.

ZHE+ Zero Headspace Extractor: Operation and Instruction Manual Setup and Operation

Setup and Operation

1. 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 800-343-5319.

2. 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.)

3. Wet both plate O-rings with reagent-grade water and place one in each end plate O-ring groove.

4. With the toggle valve open, set the sample barrel into the bottom plate, “grooved” end down.

5. Pour in the sample.

6. Center a 90 mm, 0.7 μm 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 place.

7. 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 wheels.

8. Close the plug valve down until only a relief “crack” can be seen inside the valve, and connect the male/female quick connect.

Caution: Before pressurizing to clear headspace, make sure that only a small “crack” is left open inside the plug valve. This will reduce the risk of accidentally shooting liquid sample or extraction fl uid out of the ZHE+ unit.

Warning: Do not pressurize beyond the top operating pressure of 50 psi.

9. Slowly pressurize to clear headspace according to method procedures.

10. 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 extraction.

11. 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. As soon as extraction fl uid appears, shut off the plug valve and end pressurization. Your solid sample is now ready for rotary extraction.

12. 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 pressurize.

Use with Rotary Extractors

If 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 rotating.

Maintenance and Care

The 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. 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 corrosives.

Periodically 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. It may be necessary to replace O-rings or tighten fittings

Warranty
