What factors may cause the results of Karl Fischer Moisture Analyzer, Halogen Moisture Analyzer, and Infrared Moisture Analyzer to be less accurate?
1. The selected temperature is too high or the sample is oxidized. Lower the drying temperature;
2. The selected drying time is too short. Prolong the drying time or select the appropriate shutdown mode "weight loss per unit time";
3. The sample is not completely dry (for example: due to surface skinning). Try mixing quartz sand for drying;
4. The sample is not uniform. For example, they have different ingredients. The more uneven the sample, the more samples are needed to obtain better reproducible results;
5. The sample boils and continuously splashes to change the temperature. Please clean the protective glass;
6. When the protective glass is corroded, the heating capacity cannot be fully exerted, please clean the protective glass;
7. The external environment is unstable (vibration, etc.);
8. The console is not stable. Please use a stable operating platform;
9. The temperature sensor is contaminated or damaged, please clean the temperature sensor.
