| Abstract |
The results of a single-laboratory study of osmium analytical methods are described. The methods studied include direct-aspiration atomic absorption spectroscopy (EPA Method 7550), furnace atomic absorption spectroscopy and inductively coupled plasma atomic emission spectroscopy using direct nebulization (heated and unheated), continuous nebulization and volatilization (batch and heated continuous). Also presented are the results of several methods of sample preparation. The stability of osmium concentrations in digests over a three-week period are also presented. Method performance data including detection limits, optimum concentration ranges (linearity), spike recoveries, interferences, precision, accuracy, and recommend operating parameters are presented and discussed. |
