One quick and accurate way of determining moisture is thermogravimetric measurement using a Halogen Moisture Analyzer: the sample is weighed and heated with an infrared radiator (halogen lamp). The loss in weight is continuously recorded and drying ends once a defined criterion is reached. The moisture content is automatically calculated from the difference in weight (Measuring principle). During thermogravimetric measurement, the loss in mass cannot just be selectively assigned to a loss of water because substances other than water may evaporate when heated. This is why we speak of moisture content when using thermogravimetric procedures (Technical Terms).
