Appendix B <strong>Melting</strong> <strong>Point</strong> Certified Reference Standards 89O100MPS CRS Kit<strong>Stanford</strong> <strong>Research</strong> <strong>System</strong>s supplies a calibration kit, SRS Part#O100MPS, consisting ofthree standard compounds with rated melting points traceable to WHO CRSs. The kit isspecifically designed to check the temperature offset calibration of your <strong>OptiMelt</strong> systemaccording to WHO certification requirements and to correct the temperature offsets ifnecessary. Clear points are used for the calibration of temperature offset corrections(TOCs). For detailed calibration instructions consult Chapter 4 of this manual.The three reference substances included in the O100MPS kit were carefully selected tomatch the calibration requirements of <strong>OptiMelt</strong>.SubstanceSRS O100MPS-CRS KitStart/Stop(*)(°C)Clear <strong>Point</strong>(#)(°C )AnalysisMethodVanillin 78/88 83.0 VanillinPhenacetin 131/141 135.9 PhenacetinCaffeine 232/242 237.0 Caffeine(*) Ramping rate is 1°C/min for the three compounds.
