Extract

Sporadic displacements of substantial magnitude were observed during routine analysis in the concentration intercepts for some trace elements, together with a similar change in the sensitivity (slope) for magnesium when determined using a synthetic multilayer. These effects were traced to the electronic circuit providing correction for pulse amplitude shift with intensity.
