Hi guys and gals

Maybe this video has already been posted here, I found it very interesting and maybe it can be of help to somebody.

Where did you end up on the ratios? That’s a good looking separation!

I’m also curious, how are you guys making your standards?

I weigh my CBD or any other cannabinoid on a precision scale and dilute it with ethanol to 5mg/ml
You can use other solvents. Its important that it evaporates fast.
I have a lot of etho on hand, thats why I use it

Kinda ambiguous but, it’s a nice start into it.

@Labwork
Have you try 5% ether / 95% pet ether on standard silica 60 TLC plates?
Ive seen good seperation with CBD D9 and D8 like that however I did not try with cbn…

No, I have no pet ether on hand.
I tried hexane, heptane, ethyl acetate, acetic acid, polar express, ethanol, water, acetone, diethyl ether, toluene.

Mixed them together according to all the papers I found on researchgate about cannabinoid TLC.

I stopped trying around, because DEE:hexane was sufficient for my needs.

Chloroform with dichlormethan or 1.2-dichlorethan was mentioned in some papers.
Toluene-chloroform-methanol 100:10:1 also.

You tried it? I was curious myself, did you dry your toluene appropriately?

Drying the toluene isn’t going to do anything when you use monohydrate PTSA

i did not dry toluene and got 95% d8

Yeah that’s what I assumed, but I seemed to remember reading it was dried, however you’re correct they did specify mono hydrate didn’t they

I wonder if they dried the ptsa

They never said they did but there’s no way they got that high d9 with that much water in it

Either that or there analytics are screwed up which a few of us think they are

Supposedly neat chloroform works pretty well too. I have certainly read about TCM:MeOH:H2O systems giving good separation as well. No personal experience

Did you use the crazy high 2molar ratio of pTSA to CBD also?
