[Dsg-htcc] HTCC gas flow rate for KPP

[Youri Sharabian]

Hi George,

Yes, of course. We just started from 2 slm and gradually are going up. We want to see transition from low flow rate to the recommended 6.5 slm.Thank you.                   Youri

 Hi Youri,


 I see you have increased the flow rate to 5 slm. I will again
 recommend that you increase this flow to a minimum value of 6.5 slm.

 Hi Youri,


 I recommend you increase your CO2 flow rate. The current rate of 2
 slm is too low. I recommend a flow of 6.5 slm until the KPP run 
 is completed.


 The calculated flow rates for the HTCC are as follows;

Purge Flow - 20 slm - 1.5 volume exchanges per day- the detector
 volume will be purged in 3.4 days

Running Flow - 6.5 slm - 0.5 volume exchanges per day 

Reduced Flow - 3.25 slm - 0.25 volume exchanges per day
