A HIGH‐PERFORMANCE LIQUID CHROMATOGRAPHIC ASSAY FOR PHENYLMERCURIC NITRATE IN THE PRESENCE OF ZINC IONS AND ITS APPLICATION TO AN ASSESSMENT OF THE STABILITY OF PHENYLMERCURIC NITRATE IN ZINC SULPHATE AND ZINC SULPHATE AND ADRENALINE EYE DROPS

摘要

SummaryA high‐performance liquid chromatographic assay for phenylmercuric nitrate in the presence of zinc ions has been developed. Application of the assay to zinc sulphate and zinc sulphate and adrenaline drops before and after autoclaving demonstrates that the phenylmercuric nitrate is chemically degraded in the zinc sulphate and adrenaline drop
