Summary
The stability of instrument calibration standards for Inductively Coupled Plasma/Atomic Emission Spectrometric analysis was studied over a two-year period. Data were obtained as functions of analyte concentration, acid type, and acidity. The impact of acid concentration on signal-to-background ratios was also assessed. The results show that, with the appropriate choice of inorganic acid preservatives, most analytes maintain their integrity over extended periods; thus frequent standard preparations are not necessary to obtain valid analytical data. This conclusion allows for more efficient use of commercially purchased reference materials, which should reduce procurement costs and minimize chemical waste.
