I’ve seen 2-3 of this style

Any reviews on either of those 2?
i need something I can test disty with (within 10% accuracy) of total d9 thc content
I’ll ask Kam when he gets back from Thailand. I wouldn’t reccommend the former but let me double check I haven’t used that one with the center hole and I think it’s better.

Pay attention to the cost per analysis.
GC costs 15 cents, the Orange costs 15 dollars per.
Thats a 100:1 difference is operating cost.

For about $10,000 you can have the SRI GC which does exactly what you want and costs 15 cents per 10minute analysis to operate.
Its my understanding that devices like this generate a light reflection pattern.
Based on that pattern they conclude that the sample must be White Widow ( or some other strain of cannabis ). Then they look up White Widow’s typical potency from a data base in the cloud.
The cloud says White Widow is typically 17% THC so that’s the answer you get.
These devices do not actually measure the THC, they infer the answer, not measure it.

Exactly all of these small handheld units I’ve seen don’t actually test the composition of the material they attempt to id the strain and look it up in a database. Worthless if you ask me.
Get the best of both worlds. Buy a cheap used fid sri gc then get @srihugh1 to add the heated inj port and the proper column
Those things are worthless unfortunately. I wish they had an accurate way of testing in a small package like that though

That thing looks sweet. If be interested to see the accuracy of that thing vs an sriGC.

With gas chromatography its usually the other way around since the column through which the sample passes is typically non-polar. Non-polar column have higher temperature limits which is helpful since the temperature required to get the THC through is higher that what most polar columns can tolerate.
So a polar molecule elutes earlier in a typical GC analysis when a non-polar column is used.
The normal elution order is THCv, CBD, CBC, d8THC, D9THC, CBG, CBN
If you do find a used SRI GC then know that we will still support it and you.
Make sure the used SRI GC is a " C" model. Either 8610C or 310C.
The earlier models (before the C model ) could not heat high enough to really do a good jhob with cannabis.
The FID detector is a “must have” as it is expensive to add. So don’t waste money on a used SRI that does not already have a FID detector.
The heated injector is optional, but makes it possible to measure cannabis samples that are mostly the acidic forms ( THCA rather than already decarbed d9THC ).
If you only measure already decarbed concentrates, then the heated injector is not essential.
If you can find a used SRI with FID detector for under $2,000 then it makes sense to buy it and pay SRI to do the required updating.
If you are not sure, call us and give us the e-bay link and we will give you an honest appraisal.
