| Before analysis 40micolitres of liquid sample (to which the LODs relate) where drop-wise transferred to Whatman 42 filter paper, then evaporated to dryness. [thus, providing a concentrating step]. Both LODs and RMSE data determined. Peaks show some Self Absorption, but lower part of each calibration is linear | |||||
