Rest assured Agricor Laboratories is prepared to test Residual Solvents at the new criteria. Our test method was developed and validated using GC/MSD (Mass Spec Detector). From Day 1, our Residual Solvent Analysis utilized MSD and remains on MSD today. Only through GC/MSD can the test eliminate false positives by confirming suspected solvents through mass analysis.

GC/FID (Flame Ionization Detector), a much more rudimentary analysis, simply cannot generate confirmatory analysis and leaves the analyst guessing. Don’t let your product get held up by laboratories guessing at the identification of solvents in your samples.
