## Abstract The organic phosphorus content of 33 calcareous soils (0.1‐52.4% CaCO^3^,) was determined by the ignition method and by hydrogen peroxide oxidation. Mean values for organic phosphorus expressed as a percentage of the total phosphorus were 14.5% and 15.6% for the two methods respectively
A phase separator is described that is suitable for post-column HPLC applications. It operates with commonly used HPLC eluents and immiscible organic solvents as long as the two phases remain immiscible. It is compatible with gradient elution systems. Separation efficiency is routinely better than 0
