title: An ion chromatographic method for the simultaneous determination of inorganic phosphate, bromide, nitrate and sulphate in human serum.
abstract: A direct method for the determination of inorganic phosphate, bromide, nitrate and sulphate in 100 microliter serum is described. After a 10-fold dilution, the sample is directly injected into an ion chromatograph without further pretreatment. The method described is highly accurate, and reproducible over longer periods. The serum concentrations of the four above-mentioned anions have been determined in 20 male and 20 female normal persons and found to be in agreement with the results of earlier studies.
