Ion analyzer is one of the most widely used analysis instruments in scientic
research and practice. It is widely applied in biomedical, chemical, environmental
protection, and other elds. Manual reading and processing data with traditional
ion analyzer is not only cumbersome in operation process but also dicult to
avoid personal error. e research about ion analyzer connected to computer has
been reported in recent years [6]; however, the quantity is small, and the software
is mostly developed in text-based programming language (e.g., C, Turbo Pascal,
VB, and so on). e disadvantage of the text-based language is long developing
periods, dicult maintenance, and expandedness. e VI of ion analyzer based
on LabVIEW has not been reported yet. e VI of ion analyzer developed by
authors is developed in graphical programming language-LabVIEW 8.0. It not
only has friendly interface, easy operation, and expandability, but also can realize
automatic slope, temperature, and positioning calibrations. e system has been
applied to determine the rate constant of ethyl acetate saponication reaction
when the LabVIEW program for determining the reaction rate constant by pX is
embedded into the system. e authors have obtained satisfactory results.
