Chromatography Forum

Dear chromatographer1, everything that AICMM point out is true, I don't know how many background knowledge yours (or AICMM) customers have, but here the knowledge don't care very much, operating company (owner of well zone) contract mudlogging company and reclaim that they must have the "standard" analysis of

methane
ethane
propane
i-but
n-but
i-pen
n-pen

There is not practical reason for it, I thought that this began
when the HP M200 appear, this wonderful micro GC
with 2 channel become a standard in mud logging in 90's,
latter in 2000, for economical reason this equipment
become too much expensive in this region, but the standard
persist.


(sorry my English, I appreciate every one who is trying to understand
what want I mean)

Interscience do a Natrual Gas analyser that does C2 to C7 in Methane baseline separated in 80 seconds using two column system on a CompactGC.
Application Note AN 305 WA802A available from your local dealer

Lateral thinking (in a field that I know nothing about so take it for what it's worth) - can you do this with two intruments ?, each taking a bit longer than the target run time but alternating injections from one to the other so that the total sample throughput is as high or higher than it would be on a single instrument running faster.

Drilling companies have used the analysis of the wellhead gases for years to predict an eruption of light gases through and around the well hole. If gases leak around the drilling shaft, ie, the drill seals leak these gases, you can have the blowout which the BP rig experienced in the Gulf of Mexico and the expensive loss of life and the pollution of the area around the well, be it in the ocean or on land. $20 billion dollars doesn't compare to $20 thousand dollars for an instrument.

Inexpensive portable GCs have done this analysis well enough in the past but now these units are no longer profitable for some of the companies who have made them and they have discontinued their production.

That is why AICMM and others are providing GC units to do this analysis.

I hope for the safety of all, including the financial health of your company, that you find a solution to your need.
