Dear stdev,

The next question would then be, how often do you prepare your working solutions ? I suppose you tried to re-prepare fresh solutions after you started to get this problem ? Otherwise adsorption could be an explanation.

Did you also see a decrease in the peak areas at higher concentration levels, compared to the response you had initially ?
