19 APPENDIX B19.1 PARAMETER DEVELOPMENT - FOODS INDUSTRYFollowing are the guidelines for developing parameters.TEST TEMPERATURESBe sure to use a temperature that is high enough to drive off all the moisture but doesnot degrade the material in any appreciable way.If, after establishing a test temperature, a shorter test time is desirable, try usingHISTART temperature control. Begin with a HISTART temperature that is 20°Chigher than the test temperature.STANDBY TEMPERATURE: 80°CAdjust only with materials that would be affected with this elevated standbytemperature.When using small sample sizes of materials that lose moisture quickly, it isrecommended that the pan or the pan w/filter paper (if used) be cooled after the pantare and before adding the sample. This can be done quickly and easily by removing thepan or pan w/filter paper and fanning them back and forth a few times.ENDING CRITERIA:If expected moisture content is greater than 20% or less than 0.5%, use RATE. Ifgreater than 20% adjust rate in increments of 0.25/minute.IE:0.50%/minute0.75%/minute1.00%/minute1.25%/minuteIf less than 0.5%, adjust rate in increments of 0.05% beginning at 0.25% and adjustdown as needed.If expected moisture is between 0.5% and 20%, use PREDICT.MAX-1000 - Relaxed predict72
If smaller standard deviations are needed:MAX-1000 - Mid-range predictIf improved standard deviations are needed:MAX-1000 - Tight predictIf standard deviations are still not acceptable, try RATE ending criteria.SAMPLE SIZE: Adjust as necessary for application. Smaller sample sizes of ahomogenous material will decrease test times.TARE OPTIONS:Pan tare:StandardSample tare:When stable. Use sample tare “3 seconds” with warm orhot applications.Ultra-low pan tare: With samples having moisture levels below 1%PARAMETER DOCUMENTATION:To ensure optimum and efficient correlation, reproducibility, and for record keepingpurposes, record the following.- Standard testing - 3 Karl Fischer, 3 oven tests or other accepted reference methodprocedure.- 5 repeat tests on the MAX-1000.- Record comments on special techniques required to duplicate accurate andreproducible results.If you need assistance with parameter development or have questions concerning theoperation of the analyzer, please contact either your Sales Representative or CustomerService Representative at (800) 235-3600 or (602) 470-1414.73
