  • Page 24 EN-20 MB62 Instruction Manual 5.1.1. Good Practices of Sample Preparation Characteristics, preparation and size of the sample are all important contributing factors in increasing speed and the quality of the measurement process. Sampling and the sample preparation have a great influence on the reproducibility of the measured results. It is also important that the sample being investigated is a representative part of the total amount of the sample under test.
  • Page 25 MB62 Instruction Manual EN-21 Liquid substances Liquid substances (e.g. dispersions) often tend to form drops on the sample pan owing to the surface tension of the liquid. This prevents a rapid drying process. The use of a commercial glass fibre filter shortens the drying time by a factor of 2 to 3. The glass fibre filter distributes the liquid sample over a wide area as a result of its absorbent action.
  • Page 26 Occasionally, following recording of the initial weight of the sample and before the actual drying, the test substance is subjected to further treatment. The Moisture Analyser from OHAUS offers this possibility in the "manual" operating mode. Such applications could include: •...
  • Page 27 MB62 Instruction Manual EN-23 The preceding table is based on the assumption that the sample is ideal, homogeneous and its moisture can always be separated completely and free from decomposition (e.g. moist sand). Deviations always comprise the uncertainty, which depends on the sample, and the repeatability of the instrument.
  • Page 28 EN-24 MB62 Instruction Manual 5.1.2. Steps to Make a Measurement Prerequisites • The correct Method is configured and loaded (refer to Create a new Method (on page Load a Method (on page 31).) Measurement Procedures 1.

In MB62, users can creates up-to 20 methods. Related information Parameters (on page 26) User Operations (on page 30) 5.2.1.
  • Page 31 5.2.1.2. Drying temperature The drying temperature range of MB62 is 40°C - 200°C. Good practice of Selecting Drying Temperature The drying temperature exerts a controlling influence on the measurement time. It must be selected so that the sample neither decomposes nor changes its chemical structure.
  • Page 32 (cooling effect through endothermic vaporization). In certain cases, local heating and decomposition could still occur at the sample surface. 5.2.1.3. Switch-off criterion (SOC) Switch-off criterion defines when the instrument should end the drying. MB62 contains three types of Switch-off criterion:...
  • Page 33 MB62 Instruction Manual EN-29 Switch-off Definition criterion The switch-off criterion is based on a weight loss per unit of time. As soon as the mean weight loss is less than a preset value during a specified time, the instrument considers drying as complete and automatically discontinues the measurement process.
