Summary on portable isotope coal analyzor

This paper described the principles,structure and calibration method of the portable isotopic coal analyzor based on the isotopic technology of ash determination with γ-ray back-scattering method,and introduced the structure and characteristics of software and hardware of the upper and the lower part of the analyzor.It showed that the analyzor had many advantages such as short determination time,small size and weight,and it could be also used in the determination of moisture,which has good benefit for practice.
