Historical Standard: ASTM C1590-04 Standard Practice for Alternate Actinide Calibration for Inductively Coupled Plasma-Mass Spectrometry
SUPERSEDED (see Active link, below)
ASTM C1590
1. Scope
1.1 This standard practice provides guidance for an alternate linear calibration for the determination of selected actinide isotopes in appropriately prepared aqueous solutions by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). This alternate calibration is mass bias adjusted using thorium-232 ( 232 Th) and uranium-238 ( 238 U) standards. One of the benefits of this standard practice is the ability to calibrate for the analysis of highly radioactive actinides using calibration standards at much lower specific activities. Environmental laboratories may find this standard practice useful if facilities are not available to handle the highly radioactive standards of the individual actinides of interest.
1.2 The instrument response for a series of determinations of known concentration of 232 Th and 238 U defines the mass versus response relationship. For each standard concentration, the slope of the line defined by 232 Th and 238 U is used to derive linear calibration curves for each mass of interest using interference equations. The mass bias corrected calibration curves, although generated from interference equations, are specific to the instrument operating parameters and tuning in effect at the time of data acquisition. Because interference equations are part of the normal ICP-MS manufacturer's software package, this calibration methodology is widely applicable.
1.3 For this standard practice, the actinide atomic mass range that has been studied is from amu 232-244. Guidance for an extended range of amu 228-248 is given in this practice.
1.4 Using this practice, analyte concentrations are reported at each amu and not by element total (that is, 239 Pu versus plutonium).
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
