On-line dilution and determination of the amount of concentrated hydrochloric acid in the final products from a hydrochloric acid production plant using a sequential injection titration system

Direct determination of phosphate in urine by sequential-injection analysis with single on-line dilution–calibration method and photometric detection

“…Compared to FI, SI is characterized by manifold simplicity, versatility, convenience and speed of calibration, and low consumption of reagents and sample and has been shown to be the most versatile technique, also suitable for automated on-line dilution under nonequilibrium conditions. So far, only a limited number of SI systems for on-line dilution have been reported [12][13][14][15][16][17][18][19][20]. Among them, the single standard calibration and dilution method employing a dilution conduit for creating a concentration gradient of the injected analyte zone seems to be the most attractive and efficient [12].…”

Sampling, Dilution, and Loading Device-coupled HighPerformance Liquid Chromatography Method for Successive On-line Analyses of Major Carbohydrate Products in Immobilized Cellulase Hydrolysate of Paper Cellulose

“…Most of the on-line dilution schemes [15][16][17][18] described in the literature were complicated and used expensive equipment, while off-line dilution procedures often exhibited sample loss and tedious procedures. It would be wise to simplify the on-line dilution scheme in a more convenient and economical way.…”
