SEA1200VX performs high sensitivity measurements of Aluminum alloys resulting in superior "limit of detection" and excellent repeatability.

Measurement of cadmium (Cd) in alminum (Al) alloy

Excellent linearity of the calibration curve for aluminum alloys was created at optimal measurement conditions resulting in a detection lower limit of 3.6ppm Cd at a measuring time of 300 seconds.

Measurement of lead (Pb) in alminum (Al) alloy

A detection lower limit of Pb 4.2ppm is achieved due to excellent linearity of the calibration curve at optimal measurement conditions.
