| 520 | $aThe objectives of adding computer control to the X-ray diffraction analysis developed for assessing quartz in airborne dust samples collected in mines were two-fold. First, to minimize counting time: samples with a lot of quartz required scanning of the peak over 3º 2 angles for a short counting time, whereas samples with little quartz required a longer counting time over a narrower scan. Thus both required feedback control to reduce average sample analysis time. Second, interference was frequent and variable even in one mine: to control this it was desirable to analyse on two or more diffraction lines. The computer control was set up to run each sample on up to four diffraction lines, stopping when any pair of lines gave results agreeing within the limits of error chosen | ||
