摘要: Modified reverse flow injection analysis is introduced as a novel means for monitoring purposes and online process control. The technique based on the of standard solutions into continuously flowing sample stream. transient detector response occurring shortly after reflects deviation between analyte concentration stream injected. Interpolative calibration check nominal values are two interesting execution modes presented. beneficial features approach discussed exemplarily demonstrated practical problems. Experimental conditions given photometric determination chloride in tap water, phosphate surface water potentiometric fluoride. respective advantages over common systems outlined.
