Measurement of Alminum (Al) Alloy Sample
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.
Measurement of chromium (Cr) in alminum (Al) alloy
The detection lower limit of Cr in Al alloy is 18ppm at 300 seconds.
Repeatability at 300 seconds measurement
Repeatability tests at 300 seconds show superior Cd CV value of 1%, Pb CV value of 0.2%, and Cr CV value of 1.7%.
