  • Page 28  Some samples contain more than one volatile material, for example, nylon resins with large amounts of unpolymerized material (Caprolactam). In these cases, the rate will fall to some fixed value when all the moisture is evaporated but while the monomer is still evaporating. The graphical display available from the Main Test Screen is of great help in visualizing these cases.

  • Page 64: Sample Preparation, Testing And Analysis

    SAMPLE PREPARATION, TESTING AND ANALYSIS Balance Temperature Stability 6.1. The force balance in the MAX 5000XL is most accurate in a stable temperature environment. To maintain a constant balance temperature, whether the instrument is testing or idling, the instrument heats the balance at initial power-up and maintains the balance temperature at all times.

  • Page 65: Preparing Granular And Powdery Samples

    Preparing Granular and Powdery Samples 6.2. The MAX 5000XL 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 uniform mixture.

  • Page 66: Selecting The Optimum Sample Size

    Selecting the Optimum Sample Size 6.4. Each particular sample will have its own optimum sample size. Best results will be obtained if the sample consists of a single layer of particles, as long as this is sufficient to develop a weight loss of 10 milligrams or more. A rule of thumb is "the lower the moisture, the larger the sample."...
  • Page 67 A typical drying curve is shown at the right. Section (A-B) represents the sample's weight loss as it heats from room to testing temperature. Section (B-C) is linear, representing moisture loss from the interior of each particle of the tested sample. Section (C-D) is exponential in nature and represents the final evolution of moisture from within the particle.

  • Page 68: Determining Proper Test Temperature

    Determining Proper Test Temperature 7.2. If the moisture of the sample material is known, as determined by a reference method, the MAX 5000XL's temperature can be adjusted until test results correlate with the established moisture concentration. If the moisture is not known, prepare a moisture versus temperature curve to decide the proper test temperature for a particular sample.

  • Page 69: Selection Of Ending Criteria

    Selection of Ending Criteria 7.3. The decision of which ending criteria to use is application dependent. Best results are typically given with PREDICTION or RATE, rather than TIME. Experiment with your particular sample to determine which criterion is best for your product. See Ending Criteria on page 26.

  • Page 70: Performance Verification

    PERFORMANCE VERIFICATION Periodic checks of the system are recommended to verify proper system operation. These periodic checks will satisfy some quality assurance requirements as specified in your quality assurance/control policy. A log is recommended, either hand written or computer managed, which will record the weight test results, sodium tartrate test results, and retained samples’...

  • Page 71: The Precision Weight Test

    The Precision Weight Test 8.2. The precision weight test consists of performing the weight test in Section 8.1 multiple times to determine the instruments repeatability. This is a more critical verification of the instrument’s performance. Mean, Standard Deviation, and Relative Standard Deviation are calculated using the following formulas.

  • Page 72: Sodium Tartrate Test

    Sodium Tartrate Test 8.3. The sodium tartrate test verifies the heater and force balance operation. Sodium tartrate dihydrate is a chemical with a known moisture concentration that releases moisture at temperatures greater than 120º C. Because of its consistent moisture concentration, it is used as a standard in moisture measurement using oven or titration methods.

  • Page 73: Precision Sodium Tartrate Test

    Precision Sodium Tartrate Test 8.4. Perform the sodium tartrate test in Section 8.3 multiple times to determine the instruments repeatability. This is a more critical verification of the instrument’s performance. Mean, Standard Deviation, and Relative Standard Deviation are calculated using the following formulas.

  • Page 74: Retained Samples

    Retained Samples 8.5. The weight test and the sodium tartrate test are usually sufficient to satisfy industry guidelines for quality control in moisture measurement. Some additional checks can be performed using replicate testing of retained samples. Retained samples, when stored under airtight conditions, should maintain moisture levels for long periods.

  • Page 75: Web Server

    WEB SERVER ® An optional Web Server can be purchased for the MAX 5000XL. MS Internet Explorer Version 6 or higher (IE) is used to view a calibration report, view the LCD screen, save/load memory starts, and save test results.

  • Page 78: 10. Routine Maintenance

    10. ROUTINE MAINTENANCE The MAX 5000XL requires routine cleaning to keep the test chamber free of excess sample material. Failure to keep the instrument interior clean reduces its accuracy and repeatability. Sample material collecting in the test chamber prevents free movement of the pan support.

  • Page 79: Shroud Gasket

    Shroud Gasket 10.2. The shroud gasket creates a seal between the heater shroud and ceramic plate. Over time, this gasket will require replacement. Check the shroud gasket (AZI P/N 300-0446) regularly for cracks or deterioration. Perform a Kimwipe test to verify the seal’s integrity.
