A Systematic Approach to Standard Addition Methods in Instrumental Analysis

In nearly all of the literature on techniques in analytical chemistry the methods of standard addition are generally sparse and often included as an afterthought. y e t these techniques are exceedingly important particularly in the areas of instrumental methods such as spectrophotometry, atomic absorption (AA), and electrochemistry where the inherent utilitv of the instrument mav be reduced bv, a .Door set-UDof thcchrmit~ilsystem. ~ l t h u u y hmudwn chemical instrurnkts haw high iensitivitv and
