"Determination Of Water By Flow Injection Analysis With The Karl Fischer Reagent"
Anal. Chim. Acta 1980 Volume 114, Issue 1 Pages 199-208
Ingrid Kågevall, Ove Åström and Anders Cedergren

Abstract: A method for the determination of water in organic solvents by flow-injection analysis (f.i.a.) is described. The method, which is based on the reaction between water and the Karl Fischer reagent, is capable of 120 determinations per hour. The concentration range 0.01-5% (v/v) of water can be covered by using a single Karl Fischer reagent solution. The results obtained with a specially constructed potentiometric detector showed a relative standard deviation of less than 0.5% (v/v). This value was about 3 times less than that obtained with a spectrophotometric detector. The f.i.a. technique is shown to offer some unique possibilities in minimizing interferences associated with the standard Karl Fischer batch titration method.

"Determination Of Water In Ethanol And Acetone By Direct Injection Enthalpimetry Based On The Heat Of Dilution"
Talanta 1984 Volume 31, Issue 1 Pages 82-84
Walace A. De Oliveira and Celio Pasquini

Abstract: Two analytical procedures based on the magnitude of the heat of dilution and direct injection enthalpimetry have been developed for determination of water in ethanol and acetone. The results obtained by means of the heat of dilution were compared with the values given by pycnometry, and gave a relative difference in the range 0.2-3%. The precision depends on the slope of the calibration curve, which varies with the procedure and the concentration of the sample.

"Spectrophotometric Approaches To The Determination Of Water In Acetone By Flow Injection Analysis"
Analyst 1991 Volume 116, Issue 10 Pages 1043-1049
Miguel Guzman, José Luis Pérez Pavón, Encarnación Rodríguez Gonzalo, Christine Hatfield, Jaromir Ruzicka and Gary D. Christian

Abstract: Five previously reported batch techniques were applied in the flow injection spectrophotometric determination of water in acetone which involve the use of lead tetra-acetate, Chrome azurol B, dithizone, CoCl2 and K2Cr2O7. Results are discussed; the K2Cr2O7 method was the most suitable for 0.05 to 5.0% of H2O.
