Hi Youri,<br>
<br>
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,<br>
<br>
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.<br>
<br>
The calculated flow rates for the HTCC are as follows;<br>
Purge Flow - 20 slm - 1.5 volume exchanges per day- the detector
volume will be purged in 3.4 days<br>
Running Flow - 6.5 slm - 0.5 volume exchanges per day <br>
Reduced Flow - 3.25 slm - 0.25 volume exchanges per day<br>
