The chemical composition of the cesium salt produced by KBiL has hitherto been doubtful, but it has been found to be Cs3Bi2I9 or 3CsI.2BiI3 by careful ex-periment. Also the composition of the cesium salt produced with the NaBiI4 reagent is thought to be the same as that for the KBila reagent. As the chemi- In working up this data, the analytical chemists used at least four different approaches to correct the signals: (a) ignoring both the calibration blank, CB, and the reagent blank, RB, which clearly is incorrect; (b) using the calibration blank only; (c) using the reagent blank only; and (d) using both the calibration blank and the reagent blank.. The first four rows of Table \(\PageIndex{2 2.

The reagent does not measure only phenols, but will react with any reducing substance. It therefore measures the total reducing capacity of a sample, not just phenolic compounds. This reagent is part of the Lowry protein assay , and will also react with some nitrogen-containing compounds such as hydroxylamine and guanidine . [2]
