Appendix D OptiMelt Remote Programming 107CHEM (?) {s}PHTH (?) {i}THCF (?) {x}MPRG?Chemical NameThe CHEM command sets (queries) the Chemical Name as it will appear in themelt report. The string s is the name and is converted to UPPER case.ExampleCHEM?CHEM caffeineReturns the Chemical Name string.Set the Chemical Name to CAFFEINE.Thermodynamic Melting PointThe PHTH command sets (queries) whether the instrument will useThermodynamic correction. The parameter i selects Skip (Pharmacopeia MP,i=0) or Calculate (Thermodynamic MP, i=1).ExamplePHTH?PHTH 0Returns the Thermodynamic MP mode.Set to Pharmacopeia MP (skip thermodynamic correction).Thermodynamic Correction FactorThe THCF command sets (queries) the thermodynamic correction factor to thevalue x. This factor is used to calculate the thermodynamic MP.ExampleTHCF? Returns the Thermodynamic Correction factor.THCF 1.1 Set the Thermodynamic Correction factor to 1.1.Read Melting Point ReportReturns the text melt report specified by the last MPRS command.
