The sealed proportional counter had a collimator and was sensitive to X rays from 1.5 to 20.2 keV. The CDTE detectors had discriminators that provided threshold values of 15, 30, 60, and 90 keV. The investigation was primarily concerned with X rays produced in the atmosphere by precipitating electrons.

A bench-top elemental analyser that is capable of operating in three modes: CHN, CHNS and Oxygen, is fully automated, and includes a 60 position autosampler. CHN and CHNS are determined via the classical Pregl-Dumas method where samples are combusted in a pureoxygen environment. Oxygen determination is based on the classical Unterzuacher method which incorporates the modifications of Oita, Conway and Culmo where samples are converted to carbon monoxide following after pryolisation and reaction with a platinised carbon reagent. The analyser has an accuracy of <=0.3% and a precision of <=02%. The analytical range is from 0.001 -3.6 mgs for C, 0.001-1.0 for H, 0.001-6 mgs for N and 0.001 to 2.0 mgs for S and O.
