Automation of a manual spectrometer by use of a hardwired angle programmer and microcomputer

The manual X-ray spectrometer, PW-1410, has been upgraded to a level of automatic operation through the addition of a hardwired Angle Mode Programmer, a Motor Controller and by interfacing a dedicated microcomputer. It is the purpose of this communication to describe the system together with data reduction software developed for the microcomputer. This paper will also discuss quantitative analysis techniques using matrix mass absorption coefficients measured with a new absorption cell attachment.
