Using Melt Graphs 91Appendix CUsing Melt GraphsMelt GraphsIn order to provide a real-time display of the changes detected by the digital camera, agraphical representation of the “melting process vs. temperature” can be plotted duringthe analysis.The plots (referred to as Melt Graphs) are a simplistic representation of the meltingprocess calculated by the digital image processor, and are stored in memory as part ofeach final report. Melt Graphs can be displayed during and after a melt on the front panelof the instrument or on a computer screen (using the MeltView software and USBconnection to a host computer). The Digital Image Processor uses the calculated MeltGraphs to detect onset, meniscus and clear points based on user-programmable thresholds(i.e. Onset%, Clear% and Single%) stored in the OptiMelt’s internal memory.Melt Graphs are generic plots, routinely used to review the changes observed by thecamera during a test, and to fine tune automation parameters (i.e. detection thresholds) tobetter match visual and automated determinations. Melt Graphs are also appended to allprinted reports for GLP validation of your analysis results.OptiMelt Automated Melting Point System
