Photometric titrations—XI Construction and evaluation of a semiimmersion phototitrator

Automated spectrophotometric titrations

“…The advantages of spectrophotometric titrations are well known (1-6, 18, 19). Spectrophotometric titrations are especially useful for determining low concentrations of substances, for analyses involving reactions in which the equilibrium is unfavorable at the end-point, and for determinations in which there are no suitable indicators but one of the species involved has an absorbance.…”
