摘要: Abstract An inexpensive analyzer for continuous recording of orthophosphate concentration has been designed utilizing instruments used in routine liquid chromatography. The determination is based on the change spectrum methyl green upon binding to molybdophosphoric acid (H. Van Belle, 1970 , Anal. Biochem. 33 132–142). Changes P 1 concentrations down and 5 μ m a sample can be displayed full-scale recorder at consumption rates 7 1.4 ml/min, respectively. Short time contact with (down 6 s) enables measurements made presence highly labile compounds such as acetyl phosphate.
