Smoothing and differentiation of data by simplified least square procedure.

The linearity of the detection system including the attenuator will directly affect the accuracy of 0 and should be considered when making calculations. Using Equation 8, resolution may be calculated for adjacent peaks that may vary in height as much as the dynamic range of the instrument. All that is required to make an accurate determination of 0 is the peak and valley heights and their respective retention distances. More information is required to calculate 0 in this derived form, but each measurement is relatively easy to make and awkward construction lines are entirely eliminated. This method could easily be applied to systems using computers for data reduction. Those computer systems using continuous sampling techniques would, in fact, acquire all necessary data and need only sufficient programming to make the calculation. R 8 Subscript i, j
