EZ Test Supreme - Colour Confusion

The instructions for performing the test with Robadope (reagent 3) plus fixer (reagent 2) state that a salmon coloured reaction will occur if primary amine is present.
However, whenever I drop reagent 3 onto my sample, it appears to be salmon pink already i.e. before I add reagent 2.
Soooo...... can anybody tell me if this sounds correct?? If so, does it mean that the pink liquid should become colourless when I add reagent 2 in the event that there is no primary amine present??
Hope that makes sense.
Cheers

I don't know, I've had the same thing happen with simon's reagant with a particular evil bit of speed that was tested, It went blue straight away without the need for the fixer. I can only assume that in my case there was already a type of chemical similar to the fixer in that speed (it was awful stuff, bad as in polluted).
 
I'm not an experienced tester, but the same thing happened to me. The phase 3 liquid is an orange/brownish color, so my common sense tells me that when I put a drop of it on a white powder it's still going to be orangish. I believe you just have to look for the reaction after putting on the phase 2. Maybe someone with more experience can give a better explanation.
 
aj, ewoud or anyone else from EZ Test:
could someone please make an effort to try and answer these sorts of questions? None of us other mods have even seen the Robadope, let alone had any practical experience with it.
 
Hi there !
Well, i am one of the first users of Robadope, since i use it for months now, and i am fully satisfied.
I tried it with more that 80 sample of E, which have been tested after in a real lab.
The test conclusions were always verified by the lab.
What i can say is that robadope DOES TURN brown with time.
this has been already mentioned to EZ TEST
I think the reagent is not really stable or sensible to oxigen.
What is importatnt is THE REACTION (with a fair bit of substance and at least 5 minutes).
No reaction, no mix !
For the moment, the tester did not lie....

As you have been using the test for a while, can you define 'a fair amount?'
EZ suggest about 1/8th of a pill. Is this what you are using for the Simon's and Robadope tests??
Also, I did send my original query to EZ but they obviously couldn't be bothered to reply.
 
Yep, it is almost 1/8 off the pill....
It s a lot i know, but i just test 1 or 2 pills with the whole test.
i just test with marquis the others.
Moreover, i always take at least 1 pill to the lab before dropping, so i know exactly what dosage are in it...
 
hey Guys,
Here's the (delayed) answer for this question.
The reagent does look a little orangey-brown. what you have to look for is a distinct color reaction to salmon red. it really shos a reaction.
as for the first step of simons going blue; I have seen that too and have no idea what causes it. weirrrd...
 
Robadope is indeed rather tricky to use and properly interpret the result.
The liquid is kind of salmon already and we have not found a way to change that yet.
Every now and then, I show this particular reaction with a Superman (pma/mdma pill) to visitors and I admit that they also have difficulties interpreting it.
Since I know what to look for, I agree that it is difficult to interpret a reaction (if it is there) but have a look at the picture again.

If there is a primary amine, there will be SOME sort of reaction. It may be hard to see but the little particles will turn reddish. A darker red than the color of the reagents. I have also seen that, once the reaction started, the liquid itself went slightly clearer. I don't know why but it is to explain that you may also see some unexpected 'reactions' every now and then, if it is a weird pill. The main thing is that reaction and the little particles in that reaction that get a color like in the picture.

Robadope is relatively new reagent. It INDICATES a primary amine. That means that if it is NOT there, there will be NO reaction. This is different from the other two reactions; if it is there, it will react.
It would have been better the other way around (if there is no primary amine, it should react) but that seems impossible with current chemical knowledge.
It also makes it rather difficult for us to properly communicate all pitfalls.
As other people also say, it seems to work.
We've verified our results with laboratory tests and it works.
It is just a different test from the other two and that requires a different approach. You are testing for something that should NOT be there.
Anyway, we've also seen stronger reactions with Robadope and if you really do not see any colorchange and reaction, your pill MOST LIKELY (no 100% guarantee!) does not contain a primary amine.
Just make sure you observe for at least 3-4 minutes.
Hope this helps
aj
