  • Page 34: Moisture Analysis Testing

    MOISTURE ANALYSIS TESTING ® ® The Computrac Series loss-on-drying moisture analysis system takes advantage of leading edge technology to reduce test times and increase precision over standard vacuum oven or convection oven drying procedures. Prior to testing, a Test Program is created with the parameters to be used for testing the sample.
  • Page 35 The microprocessor monitors the sample's weight loss during the entire testing process. Simultaneously, if using the Predict ending criteria, the microprocessor is predicting a final moisture concentration based upon the sample's rate of weight loss compared to the exponential portion of a standard drying curve. Testing continues until the predicted moisture concentration agrees within a certain percentage of the actual moisture concentration appearing on the display.

  • Page 36: Performing A Test

    7.1. Performing a Test ® A Test Program for your material must be developed prior to using the MAX 4000 for production testing: • See section 8.1 Test Programs on page 41 for guidance setting up a Test Program. This section helps you determine the proper test temperature, ending criteria, sample size, and other parameters.
  • Page 37 • The instrument will tare (zero out) the pan. This will occur instantly if the lid has been closed and the balance is stable. • Open the lid and quickly load the sample, taking care to evenly distribute it across the entire pan surface in a thin layer to get the fastest and most accurate results.
  • Page 38 • Close the lid, and the instrument weighs the sample. • The test proceeds to dry the sample. For a WEIGHT test only, immediately after the instrument weighs the sample, gently open the lid, carefully remove the 3-gram weight, and gently close the lid.

  • Page 39: Preparing Granular And Powdery Samples

    7.2. Preparing Granular and Powdery Samples ® The MAX 4000 can be used to test a wide range of products from finely ground, low-moisture powders to high-moisture slurries. For best results, the sample should be of a uniform particle size distributed evenly over the sample pan. If sample material is collected into a jar or sampling bag, shake the jar or bag to produce a more thorough mixture.

  • Page 40: Main Menu

  • Page 47: Sample Size Options

    Some samples contain more than one volatile material, such as nylon resins with large amounts of unpolymerized material (Caprolactam). In these cases, the rate will fall to some fixed value when all the moisture has evaporated but while the monomer is still evaporating.
  • Page 48 The available options are: • SAMPLE SIZE – Set as discussed above. • SAMPLE WINDOW – Set the allowable sample size tolerance. A smaller tolerance produces more repeatable results, but makes it more difficult to load a sample. Generally, pick a window size ≤ 10% of SAMPLE SIZE and less than 1g. •...
