CORRELATION ANALYSIS OF
ACCUSENSING MAS AND ICP-OES
FAST AND ACCURATE –
FIELD APPLICATION
A total of 35 groundwater samples were detected for arsenic in field by MAS. Afterwards the water samples were sealed to laboratory for ICP-OES analysis. Correlation analysis between MAS and ICP-OES figures that the correlation coefficient(r) equals 0.9818.
