Hi strob
Looks like you guessed that I was hinting at volume overload! The problem is likely to be the basicity of these compounds. I've seen a number of methods that either use higher pH mobile phase (using ammonium formate) to get better peak shape…
It’s all about transmission
Raman spectroscopy has already demonstrated itself to be a useful analytical method in laboratory and process settings, owing to straightforward optical setups, highly specific chemical signatures in spectra, and the ability…
