San Rafael Chemical Services

San Rafael Chemical Services provides quality analysis of the continually expanding array of compounds from pharmaceutical research, biotechnical and natural product development, and environmental protection.

What We Do

San Rafael Chemical Services Inc. was established in 1993 under the direction of Ralph Meibos, a 25 year veteran of chromatographic and spectrometric analysis and interpretation.


San Rafael Chemical Services specializes in HPLC analysis of biological material. For instrumentation we use Hewlett Packard’s 1090 series II / L HPLCs with photodiode array detectors to an HP 5989 A – Mass Spectrometer engine. For certain compounds and for method development the HPLC is interfaced through either thermospray or a particle beam. We also have the HP 5890 series II Gas Chromatograph for GC/MS determinations (Volatiles, Semi-Volatiles, etc.) along with other devices.

Professional associations include the American Chemical Society (ACS), the American Society for Mass Spectrometry (ASMS and the Association of Official Analytical Chemists (AOAC).
