Flame emission for accurate cesium determination in geostandards
Department of Scientific and Industrial Research,
Private Bag, Lower Hutt, New Zealand
Cesium values for 21 geostandards obtained by flame emission spectrometry are presented. Analytical sensitivity was separately determined for each sample by the method of standard addition to cancel effects of chemical interferences. Three types of chemical interferences have been found and their magnitude has been measured. Correction factors have been derived to improve the accuracy of analytical values reported in the literature that were obtained by calibration against a single standard.
