Determination of total As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se and Zn in seawater
The IMEP-40 exercise focuses on the analysis of the trace elements As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se and Zn in seawater. This PT is organised in support to the EU Water Framework Directive.
IMEP-40 is open to all laboratories having experience in this kind of analyses. The concentrations of the trace elements in the test item are in the low µg L-1 range. Laboratories whose analytical methods are not characterized by low limits of detection should not register to this exercise.
The cost of this interlaboratory comparison is EUR 368 per registration.
Test items and analytes
The test item to be analysed is a seawater sample. Each participant will receive 1 sample. The measurands are the trace elements As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Se and Zn in seawater.
General outline of the exercise
Participants are requested to perform 1 – 3 independent analyses using the method of their choice, and to report the mean, its expanded uncertainty and coverage factor k. Detailed instructions will be sent together with the sample.
