The aromatic amino acid tyrosine has proved successful as an eluent for the simultaneous analysis of all halide anions, which also causes a reduction in the iodide retention at alkaline pH, while still allowing for the separation of bromide and nitrate in contrast to p-cyanophenol containing eluents. In the respective chromatogram obtained with tyrosine as the eluent, a reversed retention is observed for orthophosphate and sulfate. This is caused by the comparatively high pH value of the mobile phase. The... 

Orthophosphates crystallise not only as tribasic, monohydrogen or dihydrogen add salts, but also as oxide, hydroxide or halide double salts. Calcium salts, for example, include oxyapatite, hydroxy-...
