• Description:
  A method has been developed for the sequential determination of chromatographically separated hydrides. The use of a sequential slew scanning monochromator as a plasma emission chromatographic detector was demonstrated. A column of Chromosorb 102 was used to separate hydrides of germanium (7440564), arsenic (7440382), and antimony (7440360) which were then introduced into an inductively coupled plasma. Each resolved chromatographic peak was monitored by the sequential slew scanning monochromator at a different atomic emission wavelength. For germanium the detection limit was 0.02 parts per billion (ppb) while for arsenic and antimony the limit was 2.5ppb. At the 50ppb level the relative standard deviations ranged from 2 to 5 percent. Analysis of the Environmental Protection Agency water quality control samples was performed to test the method for accuracy. The authors conclude that the results show the sequential slew scanning monochromator to be a viable multielement emission detector for chromatographic monitoring of hydrides. With better chromatographic conditions both the detection limits and analysis times could be improved. [Description provided by NIOSH]
