MicGrow Posted March 24, 2018 Share Posted March 24, 2018 Does anyone know of a company that offers this service in the UK? Thanks. Link to comment Share on other sites More sharing options...
Psycho Sid Posted March 24, 2018 Share Posted March 24, 2018 I've used a drug testing service, never for weed or CBD but they would be worth contacting to see if their testing will show CBD. Their results don't give a percentage just tell you if a substance is present, but it's free and they only need a small sample posted to Wales. I also know of another one in Spain, their results are alot more detailed but I think a test works out at about £60 paid in Bitcoin which is a bit of a ballache. wedinos.org are the free guys in Wales 1 Link to comment Share on other sites More sharing options...
blackpoolbouncer Posted March 24, 2018 Share Posted March 24, 2018 Would gas chromatography not be of use here? 2 Link to comment Share on other sites More sharing options...
MicGrow Posted March 25, 2018 Author Share Posted March 25, 2018 @Psycho Sid Great recommendation, thanks! They emailed me back very promptly and said that they will be testing for CBD later this year. What a great service! @blackpoolbouncer I did wonder about some kind of chromatography but I don't really know much about it. 1 Link to comment Share on other sites More sharing options...
MicGrow Posted March 26, 2018 Author Share Posted March 26, 2018 Correction, it wasn't Wedinos that got back to my enquiry about CBD testing it was another company. Still no news from Wedinos but it's only Monday morning! Link to comment Share on other sites More sharing options...
Fry Posted March 26, 2018 Share Posted March 26, 2018 Thin Layer Chromotography might be of use to you here if you're willing to go the DIY route, it's more work but infinitely more fun You can find ready made kits for it like in the link below (for a heavily marked up price of course), or look in any good chemistry book for more info on how to make your own (ready made TLC plates can be bought very cheaply on ebay). Or youtube actually, some excellent chemistry videos on the youtube. https://www.thctestkits.com/ http://www.bbc.co.uk/schools/gcsebitesize/science/triple_ocr_21c/further_chemistry/chromatography/revision/3/ Link to comment Share on other sites More sharing options...
assault and battery Posted September 5, 2018 Share Posted September 5, 2018 I’ve been looking into TLC at home and believe I can set this up but I can’t find the standards of cannabinoids anywhere. Does anyone know where I can find them so results can be interpreted? 1 Link to comment Share on other sites More sharing options...
Fry Posted September 5, 2018 Share Posted September 5, 2018 @assault and battery Quote The retardation factor (R f)values (the distance from the deposit to the tip of the peak divided by the distance from the deposit to the solvent migration front) observed in the TLC process are 0.30 for CBD, 0.27 for Δ-9-THC, and 0.23 for CBN. https://www.unodc.org/unodc/en/data-and-analysis/bulletin/bulletin_1994-01-01_2_page009.html 3 Link to comment Share on other sites More sharing options...
