Leucomalachite Green
Re: Leucomalachite Green
Hi voice. In another life, I used to work for Fisheries and we used to use malachite green as a water treatment for parasites, but I'm not sure about leucomalachite! No doubt it is a completely different beast. What do you actually use it for?
Re: Leucomalachite Green
This came from Wikipedia, so I'm not too sure how much creedence you can put on it:
Hemoglobin catalyzes the reaction between LMG and hydrogen peroxide, converting the colorless LMG into malachite green. Therefore, the appearance of a green color indicates the presence of blood.[3]

Try and chase up this link. It describes the whole process:

Re: Leucomalachite Green
It is a presumptive test for blood. Thus, if a brown stain on the carpet reacts with the leucomalachite green reagent then it is blood! At least that is the theory!

Re: Leucomalachite Green
Just an idea, why not ask the local police, they may even use something else. We had a network meeting once, and the police gave us a long chat. Said they were very happy to help if they could with, chemicals etc. Who knows perhaps they have some to give you?

Just a thought, you try Southern Biological in Melbourne, they
supply forensic science test kits, they may have this indicator.
