Determination of aluminium by inductively coupled plasma mass spectrometry in serum of patients treated by haemodialysis, dialysis solutions and tap water, and a comparison with atomic absorption spectrometry

Abstract

Inductively coupled plasma mass spectrometry has been applied for the determination of aluminium in serum (diluted 1 + 4) of patients treated by haemodialysis, concentrated solutions for haemodialysis diluted 1 + 35, haemofiltration solutions and peritoneal dialysis solutions. Matrix effects were studied from the ratio of the slope of the analytical calibration function obtained in the matrices to that in aqueous standard solutions. Comparison was made with electrothermal atomic absorption spectrometry and there is no evidence for systematic differences between the results obtained by the two methods.
