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 GTN Chem with the sampling bo
ttle 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 after it has been installed on the HERMetic 2
” ball valve but
before
opening it.
2.1.
Check that the HERMetic 2” ball valve is closed.
2.2. Open the transfer valve.
2.3. Install an external source of inert gas, using G 1/8" hole of carter winder.
The inert gas pressure
shall not exceed 0.3 bar
.A "kit pump connector FFFM" TS 20611 ND 41021 can be ordered as an
option, for this purpose.
2.4. Apply the inert gas to purge the HERMetic Sampler.
2.5. After purging close the transfer valve.
3. Check that the capacity of the laboratory bottle is at least 0.5 l. Check that the ptfe layer side of the
septum looks inside the bottle. Push up the laboratory bottle with its cap and a new septum in the bottle
holder. Do not rotate it during the installation, otherwise the needles and the septum could be damaged.
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
GTN 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. Activate the pump to transfer the liquid from the sampling bottle to the laboratory bottle.
11. 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.
12.
Open the HERMetic 2” ball valve
not more than 30°
to drain any residual liquid back into the tank.
13.
After draining close the HERMetic 2” ball valve.
14. Lift the sampling bottle and lock the crank.
15. Pull down the laboratory bottle to disconnect it from the Sampler. Do not rotate it during the removal,
otherwise the needles and the septum could be damaged.
16.
Remove the HERMetic Sampler GTN Chem from the HERMetic 2” ball valve.
