Running bottle 0.40 l. FFKM
1.
The calibration plug on top of the running bottle has to be adjusted according to the liquid to be sampled.
The plug is properly set up when the transferred quantity of liquid falls between 70 and 85% of the
capacity of the sampling bottle, i.e. between 0.3 and 0.35 l (API MPMS Chapter 8.1, § 8.3.3.3).
2. Install the HERMetic Sampler GTX Chem with the sampling bottle on top of the HERMetic 2” ball valve
by means of the quick connect coupling.
In case the air which is inside the HERMetic Sampler housing can contaminate the sample it is
recommended to purge the Sampler with inert gas after installation on the HERMetic 2” ball valve but
before
opening the valve.
2.1. Check that the HERMetic 2” ball valve is closed.
2.2. Open the transfer valve.
2.3. Install an inert gas bottle to the pump connector. The inert gas pressure shall not exceed 0.3 bar.
2.4. Apply the inert gas through the pump connector to purge the HERMetic Sampler.
2.5. After purging close the transfer valve.
3. Prepare the hose connection from the transfer valve to the laboratory bottle. Check that its capacity is at
least 0.5 l. Draw two marks on the lab bottle at 0.3 and 0.35l.
4. Open the HERMetic 2” ball valve.
5. Lower the running bottle regularly to the appropriate depth but do not hit the tank bottom in order to keep
the bottom plug closed all the time.
6. When the appropriate depth has been reached lift the running bottle back into the HERMetic Sampler
GTX at the same regular speed. Turn the crank until getting a catch that keeps the tape fully tight.
7. Close the HERMetic 2” ball valve.
8. Lower the sampling bottle until sitting on the ball of the HERMetic 2” ball valve. This will open the valve
of the sampling bottle.
9. Open the transfer valve.
10. Install the pump to the pump connector. If the liquid is air oxygenating install the inert gas bottle set up at
0.3 bar maximum.
11. With the pump (or with the inert gas) transfer the liquid from the sampling bottle to the laboratory bottle.
12. When the transfer is completed, check that the transferred liquid falls between the two marks 0.3 and
0.35 l in order to comply with API MPMS Chapter 8.1 requirements. Close the transfer valve.
13. Remove the pump or the inert gas bottle.
14. Lift the sampling bottle and lock the crank.
15. Open the HERMetic 2” ball valve
no more than 30°
to drain any residual liquid back into the tank.
16. After draining close the HERMetic 2” ball valve.
17. Remove the HERMetic Sampler GTX Chem from the HERMetic 2” ball valve.
