The cleaning headspace sampler is mainly rinsed or ultrasonically cleaned with pure water headspace vials china manufacturer , methanol or absolute ethanol. The pollution is severely wiped with a cotton swab. The force is not excessive, avoiding the destruction of the inner surface to produce active spots, and then placing it in an oven to dry at 70 degrees. After drying and cooling, the seal can be stored.
The headspace sampler cleaning steps are as follows:
1. Set the conveyor temperature to 60 ° C and set the sample loop and transfer tube temperature to Off.
2. Once the sample loop and transfer tube temperature has cooled below 60 ° C, turn off the gas to zero and remove the vent line at the outlet end.
3. Insert u an empty vial into the conveyor belt.
4. Lift the vial by hand.
5. Use a disposable syringe to draw approximately 6 ml of purified water into the HSS vent tube.
6. Lower the vial and remove it. Repeat steps 3 through 5 (two to three injections will wash thoroughly).
7. Set up an empty vial and lift it up, then use a disposable syringe to inject enough air to sweep the water out.
8. One end of the transfer tube is inserted into a beaker or similar container, and about 10 ml of water is injected from the outlet of the HSS gas tube using a disposable syringe, and then about 10 ml of methanol is injected.
9. Use a disposable syringe to inject enough air to purge the water.
10. Reinstall the line and turn on the airflow. Then, switch the vial headspace vials china manufacturer to Load-INJ dozens of times to blow all the water and methanol out of the sample valve and line.
This is the end of the introduction of Headspace sampler cleaning step. I hope it can help you.
