Mohamed Hassaan

no you should continue your treatment and measure yoru abosorbance at Max.Lamda you started with. unitl the color is compelelty gone, then calculate teh removal of color. and I know that you think you should measure with other Max.lamda but this couldnot possible to change it many times during the treatment.

tnx mr hassaan for your answer
