A calculation method of recovery rate
Quantity of recovery
Recovery rate＝
Quantity of supply−（ End of the month stock − Beginning of
the month stock ）
※ Recovery rate is calculated as purity
of recovery gas is 100％.

Recovery rate of this month was 78.7%
- The recovery rate of this month was 8.7%. The number is 2.6% lower than
last month. The recovery rate didn't start as 80%. It was a regrettable
result for the beginning of the year. It is busy time of the year so that
makes difficult to do the recovery the Helium, but with your help we could
recycle the resource without wasting. It makes cost of the Helium lowers
down.On the other hand , If the recovery rate is poor, then we have to
raise the price of the Helium supply. We ask your continuous help of keeping
up of recovery rate. And,we would like to ask you to cooperate and understand
toward the quantity of stock investigation.
- It still continues to be cold days in February, please make sure to be
safe during handling and caring the cryogen. When you drawing the Nitrogen
outside, please dress warm to prevent catch the cold. Continuously, we
ask for your cooperation on recovery the Helium.
- The shape of Helium vessels are different between Transdiscliplinary Sciences
and ISSP. Please make sure that you take out the correct vessel.
- The auto measurement machines had placed in all the gas meter in the ISSP.
Starting this February gas meter measurement, the auto measurement system
is working, but it is test driving for the adjusting network system. Please
follow the announcement and input data from the website.
- If you use other buildings facility ,please let us know about amount of
use by e-mail or in person. and inform Cryogenic Lab. We continue to ask
you for your cooperation for Helium Gas recovery.
- Recovery rate is calculated individually by buildings. It is difficult
to calculate accurately because some laboratories use Liquid Helium from
different building. If you Laboratory use Liquid Helium from different buildings than one
We ask you to declare amount of use.If you need to use Liquid Helium from other than one building, please contact
and let us know first.
※The building of Low temperature and Highly pressure Lab. are located right next to each other .So the recovery rate is combined together and calculated.
