that would work just fine
Thank you!

Yes, it will work to differentiate the enantiomers. A longer one would be more sensitive but require a larger sample.Would this purchase be enough to settle the isomer issue?

Shade system : Half Shade device which is workable on Sodium light. Suitable For Education & Training in Physics, Chemistry, Pharmacy Institutions to find out relation between specific rotation and concentration per cm or per mm thick / path of various solutions.www.ebay.com
Would this allow me to check the isomers on all my samples from this time forward?
Just for D-L isomers, not for regioisomers. Save your moneyWould this purchase be enough to settle the isomer issue?

exactlyI really don't have sufficient knowledge, but from the scientific papers I've read about identifying regioisomers of MDMA, it seems to demand much more complicated methods than a polarimeter. Or am I missing something?
I do not rely on colorimetric reagent test results, because these results are unpredictable with different ambient conditions, concentrations/dilutions, reagent formulation variations which can change in time as these reagents age.The Simon's result was odd enough to make me want to see a lab report. Has anyone here ever seen blue rings in the Simon's result?

However, I would be very surprised if the DrugsData reported no major differences between substances which react differently to these reagents ...especially if these tests are made with the same reagents, at the same temperature, concentration and at the same time (...or only days apart).
My Mecke reagent has gone bad, so I can't test with that right now. I did send this sample off to the lab, so I will let you know what the result is.
One pill....10 hours....sounds like theres definitely meth in those.Just like the meth test, mdma tests no longer work. Greed has ruined every drug. They're all made cheaply, but in a way to pass all the traditional tests. PERIOD.
I took some mdma recently,, u you know from the best dealer around and it fucking sucked ass. The only place I can still relaibly get pure MDMA is in berlin germany where they make it. Costs 2 euros a pils. and you take one and your off your rocker for 10 hours.
I mean. Theres still one person who has two types and gets clearly distinctive experiences.If the only people (capable of) saying MDMA from 20-30 years ago isn't the same as the MDMA today, why don't we instead assume their brain chemistry has changed rather than the drug? Do I have to read 307 pages to find that out? lol

I'm confused. You post first and say "Do I have to read 307 pages" and the implication is that you have not read the thread. Then you post again and say you have read it "a bunch of times." Which is it?The thing is I've read through this thread a bunch of times, but it never really sticks out as having anything conclusive - hence 300 pages of speculation. Just asking a questionthanks for the helpful reply.
I haven't read the thread in its entirety no, I've been coming to the forum for a while now, and sometimes I read an old thread. Some threads never die, so you end up reading them a bunch of times, realise you've read it before and stop reading....
I wasn't referring to tolerance. I meant brain chemistry in general. The title itself is geared to leaning the discussion a certain way.
It's now 300 pages of speculation and totally avoidable grumpiness at the end. Thanks anywho!
