ABSTRACT:
An infrared spectroscopy instrument having a transflectance type probe with an adjustable path length is disclosed. The instrument is adaptable to take both reflectivity and transmission type measurements. According to a method of use of the instrument discloses a material undergoing a change in viscosity and optical density can be measured by appropriately adjusting the path length to allow a sample of the material to enter. At a first interval, a first measurement is made using the instrument according to a transmission protocol. A second measurement is made of the sample when the sample is viscous and optically dense at a second interval using the same instrument according to a reflectivity measurement protocol.
