Chapter 26 – Chemical Analysis: Moisture Measurement

Publisher Summary The purpose of this chapter is to introduce the major measurement techniques that are available. Many commercial instruments measure some parameter that changes reproducibly with moisture concentration, and the user calibrates these instruments. The chapter discusses the major calibration techniques that the average user must be willing to employ when using such instruments. The measurement and control of the moisture content of gases, liquids, and solids is an integral part of many industries. Numerous techniques exist to choose the appropriate measurement technique for the application. It is particularly important to measure moisture because of its presence in the atmosphere. Moisture measurement may be needed to ensure that the level remains below a prescribed value or within a specified band, and the range of concentrations involved can be from less than one part per million to percentage values.
