Anyone use one of these?

Really need something for trim testing, it’s getting crazy out there. Thanks


I’ve used one, works well when the right person operates it but will be useless in the wrong hands. Careful and precise lab work is the key here.
Am considering getting one now for in house analytics.


Had one for months. Absolutely love it. I’ve ran hundreds of samples.

Analytics have been one of the most important tools I have. It’s amazing no longer flying blind.


Looking for a used gc machine


Very interested on this unit for our extraction facility, also looking for a product to work in synergy for covering other needs pesticides and heavy metals etc…

Search HPLC in the bar and look through some discussions.

There are several models/ equipment providers. Need to have competent operators

Good luck!

Hey Summer,
What type of CRM does one use to quantify the amount of butane present in a sample when using an FID detector? I am having trouble finding suppliers for certified reference materials containing dissolved butane.

I Own one it works really well especially for the price

Forgive me, what does CRM stand for?

May I ask, what you mainly use it for?

Direct message me if you would like further information.

For months? What happened?

Still have one lol, just meant I’ve been running it in past tense.

If you’re going to buy one at the base level your precision is going to be very important. Manual injection is kind of tedious and can have lots of room for error, but fine for a small inhouse lab. I’d reccomend getting am autosampler and some good sample prep tools to reduce inaccuracies and deviations.

Someone a while.back posted a link to an auto/manual syringe can’t remember what it was called though

Hey Summer, CRMs are certified reference materials. Most GCs I have seen for oil + gas industry have a valve to connect gaseous standards for quantifying the gasses (like butane) in an unknown sample. I wondered how the SRI GC could do butane quantification, and what type of standards are used for its quantitation.

here’s their documentation on butane calibration, hope this helps

Can someone give a run down on how one would test distillate with one of these GCs

you add x amount of product to a vial then x amount of solvent, mix it then inject into the machine?
