Analytical Suite Metadata

OGS Geoscience Laboratories, suite IRW-H2O, moisture content

OGS Geoscience Laboratories: Free crystalline (hydrated water) and total moisture can be determined from rock samples and other materials.  Free water (H2O-) is driven off at 105°C and crystalline water (H2O+) at 1000°C.  The moisture is then measured by infrared absorption.
