FAQ/TCP-HF EPA Question 2

Q:
A CHEMEON TCP-HF EPA bath is made-up of 25% CHEMEON TCP-HF and 25% EPA, can the EPA be analyzed for concentration separately from the TCP-HF even though they are both in the solution?
 
 
A:
Yes. The characteristic wavelength is at 294nm, which is in the UV range, so you have to use a UV-VIS spectrophotometer as opposed to a cheaper Vis spectrophotometer. The spectrophotometer that we have been recommending to our customers for CHEMEON TCP-HF analysis is not capable of analyzing CHEMEON TCP-HF EPA.
