Detection of aluminum by LAMMA spectrometry in plasma and in synovial liquids of patients on chronic dialysis.

The LAMMA (Laser Microprobe Mass Analysis) provides a semi quantitative analysis of mineral and organic ions. This microprobe has been applied in determining the aluminum detection threshold in sera or in synovial fluid of patients on chronic dialysis whose treatment includes some aluminum compounds. The limit of aluminum detection in a lyophilised sera is about 4 ppm that allows to expect on equivalent threshold in biological in heterogous matrices.
