On a related note, we have been having problems with a recent batch of exetainer vials purchased from Labco (UK)... The vials are marked as the "new thread" design... About 1 in 10 seem to leak, which sometimes trips the source on the machine... Has anybody else had problems with recently purchased exetainer vials? I think Ill send a short note to the supplier... We've bought >1000 vials from Labco over the past 12 months and never had a problem with leakage... Our old beast of a machine (MAT 252) and GasBench are working fine...

Dear all,
We have a problem on our multiflow carbonates
Bitter to introduce samples or references carbonates in vials, after
automatic injection of the acid, after a calibration in 70°C during 2 heurs
At the time of the analysis, there is no more CO2 in vials
The CO2 escapes in the stage of preparation at the time of the injection of
the acid
When I injectele CO2 in vials manually and I waits for 2 heurs I discover
the CO2
So there is no problem of leaks on vials
If you have to meet this problem, I waits you for proposition and diagnose
