An analyser incorporating an internal extractive cell in which the measurements are made. The low volume of the extractive cell makes the system suitable for applications where fast response and small gas volumes are important.
DOAS-R In-situ Stack Analyzer An analyser which interfaces with optics designed for durability, for in-situ, real time stack and duct measurements. fibre optics may be used to bring the light to and from the stack optics. Depending on the species being monitored fibre lengths of between 1 and 10 m can be used. In-situ monitoring is only applicable for low dust environments.
