Specac’s Oil in Water Analysis Kit contains all the necessary FTIR instrument accessories to implement ASTM test method D7066-04 for the analysis of total recoverable oil, grease, or petroleum hydrocarbons in water. The kit comprises of three matched pairs of infrared grade quartz cells supplied in 10, 50, and 100 mm pathlengths and a 3` x 2` mounting holder.  The cells are stoppered to prevent loss of volatile materials, and have large filling ports to ensure quick and efficient introduction and removal of the sample. Matching of the cells ensures precise and repeatable measurements.
