FIELD: physics. ^ SUBSTANCE: apparatus for X-ray radiometric analysis of the composition of pulp and solutions consists of two parts, one of which is a processing part and is embedded into the wall of a container with the analysed liquid and has a hole through which radiation passes, the second part of the apparatus is mounted outside the container and is a housing with a hole in the end part through which radiation passes, having radionuclide radiation sources and a detector, where between the processing part of the apparatus and the end part of the housing there is a chamber with cylindrically shaped helium filler, the end walls of which are made from material which weakly absorbs characteristic X-ray radiation of the analysed element. One of the end walls of the chamber is in direct contact with the window of the detector. The side surface of the chamber has two holes for blowing helium and inside the chamber there is a sensor for detecting rupture of the material of the wall of the helium chamber in contact with the analysed liquid. ^ EFFECT: high accuracy of analysis and wide range of analysed elements. ^ 2 tbl, 1 dwg |
