any technique to analise what is my product?
« on: October 13, 2016, 03:21:47 PM »
hi! i have some strange by-product, intermediate, or something... i prepared inorganic complex, and it is contaminated with something (have problems with purification, identification as well), when i measure metal NMR, i can observe signal of my product (which should be yellow), but it is yellowish and white (or white-beige). How could i determine, what is inside, beside my product? could Electrospray measurement help me (ESI-MS)? as far as i know, it can tell you if you have some desired compound structure, but what if it is a mixture? is there any technique to analise what is my product?

In the first instance you need some form of chromatography to try to measure the purity of your sample. I would suggest thin layer chromatography (TLC) as a first step. Simple, fast & cheap.

Do a literature search for TLC of your desired product to find appropriate conditions.
