The Hoffmann method is a procedure for reference interval estimation using routine clinical results. Many authors incorrectly prepare Hoffmann plots on a linear rather than normal probability scale. We explore the consequences. This was investigated algebraically, by random number simulations

The widely used calcium dye reagent, o-cresolphthalein complexone, was replaced by the less well known metallochromic indicator Arsenazo III in a selective multitest analyser. Calibration stability increased from 12 hours to more than 48 hours. With the Arsenazo III reagent

The determination of proteins with arsenazo-DBN and Al3+ by Rayleigh light-scattering (RLS) is described. The weak RLS of arsenazo-DBN and BSA can be enhanced greatly by addition of Al3+ in the pH range 5.3-7.0; this resulted in two enhanced RLS
