Hello,
I am a molecular biologist by training and so am a bit rusty on some of th=
e apparatus and
techniques that can be used for more chemical type studies.
However, I am interested in determining the "purity" of a complex mixture =
(a plant extract)
with respect to other contaminating mixtures from, for example, other plan=
t species. I also
need to process many samples with great rapidity and so organic extraction=
and HPLC etc
are probably too slow. I was wondering if the absorption spectra (like for=
stellar objects) of
a reference sample could be compared to an unknown and additional absorpti=
on bands
subtracted to help identify the possible contaminant by comparison to a da=
tabank of
potential contaminating substances (or mixtures). Like I said, I'm not ver=
y familiar with
the techniques that might be employed or the equipment. So, would I need a=
flame
spectrometer (or is that a photometer?) to generate the absorption spectra=
? And can anyone
with more experience give me an idea if this might work?
Thanks for any suggestions,
Please reply by e-mail.
Mark
