[DIYbio] Need some help with my experiments.

  I am an amateur scientist currently doing experiments in the field of prebiotic chemistry.  I do these experiments at home, which I then publish on YouTube.  I have a problem that I need help with.  Although I am able to research which experiments have been done in the field of prebiotic chemistry, and, for the most part, I am able to replicate them, I have a problem with analyzing the results of my experiments.  Some experiments which have been done by researchers yield products in millimolar amounts.  I am restricted right now to doing experiments which I can only test using reagents, or I do have a UV/VIS spectrophotometer.  But that simply won't cut it if you have products which are produced in minute quantities.  I was wondering if there are labs which would allow me to send samples so that I can have the analysis done by HPLC, gas chromatography, etc., since I don't have this type of equipment at my disposal.  Thanks very much for your help.
