@FaithfullJohn I, very successfully, used the cut and weigh method to quantify chromatographic peaks. In an attempt to increase the mass of each peak (and therefore, I reasoned, precision) I tried photocopying onto OHP sheets but quickly found the precision was worse... I figured the thickness of the OHP sheets was less consistent than paper. But this was 40 years ago...
