SRI Instruments Cannabis Testing GC

Gas Chromatograph can test for THCA, CBDA, etc. GC is the least expensive method (about 15 cents per sample ) for testing cannabis potency and has long been the choice of many labs including the US Government’s own lab.

With our cannabis GC, you can measure CBD / THC potency levels of your cannabis product or your harvest, or verify lab results in 5 minutes. No prior experience with gas chromatography is required. We offer 4 hours of free training, and are available 24 hours a day thanks to our tutorials on our YouTube channel - https://www.youtube.com/channel/UCQHQDR6_nsDKDUboEaW1R6g

SRI has released a GC model that is pre-configured to test Hand Sanitizer

Our model 310 medical marijuana GC system tests marijuana for cannabinoids (THC, CBD, CBN, etc.), terpenes, as well as residual solvents. It is a fast, simple, and precise way to test your product, while providing a laboratory grade analysis. The best part is that no prior experience with lab equipment is necessary. You can learn to use our GCs through our YouTube Channel (link below), as well as the free training offered at our Los Angeles area office. Below you can watch the 5-part series of tutorial videos that will aid you in using your 310-MM GC for cannabinoids.

Most SRI Instruments GC systems include 4 hours of free training when purchased new. Due to the COVID-19 crisis, in-person training sessions and visits to our facilities are postponed until further notice. Our customers can rest assured that they will be able to schedule their training sessions once business procedures return to normal. We thank you for your understanding during this time.

SRI Instruments is a manufacturer of high quality chromatography instruments and accessories. Why choose an SRI Instruments GC or data system? 1. Our instruments are typically HALF (or less) the price of comparable units from other manufacturers. 2. Our instruments are small enough to ship FedEx/UPS or as accompanied airline baggage and they come in a rugged, re-usable shipping container. 3. Choose from 16 GC detectors, and mount up to 4, or more (if compatible) on one GC. No one offers more detector choices.

We have created a "Medical Cannabis GC" playlist on our YouTube channel, which offer insight on how to use our GCs for the measurement of cannabinoids. Access it directly clicking on the video below:

If you are in a legalized medical cannabis state, and you need to perform cannabinoid measurement, our models 310 and 8610C are laboratory grade GC systems configured to provide a complete cannabinoid analysis (THC, CBD, CBG, CBN, etc). Please visit our page or site www.srigc.com for more information.

Gas Chromatograph can test for THCA, CBDA, etc. GC is the least expensive method ( about 15 cents per sample ) for testing cannabis potency and has long been the choice of many labs including the US Government’s... own lab. HPLC systems can also be used to test cannabis although the equipment is more expensive to purchase and also more expensive to operate ( about $5 per sample ). HPLC has until now had one advantage over GC in that it can test for THCA as well as d9THC. THCA is the precursor molecule which the cannabis plant produces. With time and heat the THCA molecule loses one carbon and two oxygen molecules ( de-carboxylates ) to become d9THC. If the cannabis is smoked, the heat of the flame instantly decarboxylates the THCA into d9THC. Edible forms of cannabis ( medibles ) are normally prepared with cannabis which has been deliberately decarboxylated prior to its addition to the flour or sugar medible ingredients. To verify that all the THCA in the cannabis leaves and flowers has been 100% decarboxylated ( usually by simmering with butter, or otherwise heating above 100C ) it is useful to be able to measure the THCA and also the d9THC in the same analysis. Previously this was not possible with GC because the GC vaporizes the sample which is injected and due to the high heat, instantly decarboxylates any THCA in the sample, converting it into d9THC. Recently we have learned how to stabilize the THCA molecule ( derivatize ) so it does not decarboxylate in the GC so we can measure THCA and d9THC separately in the same analysis just like using a HPLC but at much lower cost than buying and operating an HPLC system.

SRI also manufactures more capable gas chromatographs for testing cannabis. http://www.srigc.com//produ/medicalcannabis-cannabinoid-gc These GCs can distinguish between CBD and CBC, and... between THC and CBG which the simpler Model 420 can not do. The more capable GCs allow for more sophisticated analyses demanded by professional labs. The SRI 8610C is the perfect size GC ( gas chromatograph ) for measuring CBD, CBDA, d8THC, d9THC, THCA, CBC, CBG and CBN levels in medical cannabis. It can also be used to test for synthetic cannabinoids like SPICE, butane residuals, terpenes, aromas and edibles. The basic cannabis testing GC is $12,170 ( Sept 2016 prices ) with a single FID detector and column. A simple 5 minute column change converts from cannabinoid analysis to residual solvents or terpene analysis. With 2 or 3 FID detectors and columns, cannabinoids, residual solvents and terpene profiles can all be performed simultaneously on one GC with no hardware changes, completely avoiding downtime from column changeovers.The included built-in 50C incubator speeds up the extraction process and is especially helpful in getting concentrates, medibles and/or butters to dissolve.
