  • Page 41: Applications

    Applications Moisture Analyzer is applicable to a wide variety of samples including powders, liquids, pastes, slurries and some solids. Application considera- tions include sample composition, sample preparation, sample presenta- tion, sample size, drying parameters, desired precision, accuracy and analysis time. Developing a drying procedure on the analyzer is relatively straight for- ward when a standard convection oven method has already been established for your sample material.
  • Page 42 1. Glass pads - Circular glass pads are generally used for liquids, pastes and slurries. Samples subject to crusting over should be placed between two glass pads. Less viscous material can generally be added to a single pad using a pipette. Typically, between a 1.0 to 2.0 grams of sample is used for testing and should be evenly spread across the pad in a thin layer.

  • Page 43: Analytical Performance

    Analytical Performance The analyzer performance is dependent on a good weighing environ- ment, calibration of weight and temperature, and an optimized drying procedure. The performance of the analyzer can be measured through the statistical determination of precision, accuracy and analysis time for a given sample type.
  • Page 44 STEP 1 - Sample Preparation. As discussed previously, a sample preparation technique should be cho- sen to: 1) Provide a representative sample testing. 2) And allow rapid moisture loss. One would typically begin with a sample preparation the same as what is presently done for the standard method.
  • Page 45 • For powder samples, generally 2-10 grams is sufficient. • Liquid samples with a single sample pad general require greater than 0.5 grams but less than 2 grams. • Pastes with two glass pads will need greater than 1 gram but less than 3 grams.
  • Page 46 To achieve the most accurate results, the analyzer must permit the com- plete liberation of volatiles from the sample. This can be seen by the ana- lyzer to a resolution of one milligram weight loss (over up to a 99.9 minute of time.
  • Page 47 A). High to Low two step drying procedure. The primary reason to develop a high to low two step drying procedure is to reduce analysis time. With this feature an initial TEMP 1 temperature can to selected to drive off much of the volatiles, however if the sample is kept at this temperature eventually scorching would occur.
