摘要
A system and method for spectrophotometrically measuring the total alkalinity of a liquid sample. In a particular aspect, the method involves equilibration of a CO2 gas with a sample solution across the permeable walls of a Teflon AF 2400 liquid core waveguide. The waveguide acts as both an equilibration membrane and an optical cell in which spectrophotometric pH measurements are obtained via measurements of absorbance ratios.
