1 Introduction
The Metrohm 824 Easy Sample Changer is an instrument for numerous
applications. It was specially developed for the industrial or analytical
laboratory and therefore covers a wide spectrum of applications. It pro-
vides indispensable support when processing a large sample series
throughout the whole titration sector, for various measurement jobs, or
for other analytical purposes.
Due to the well-developed communication interfaces (parallel remote
control and serial RS 232), not only can it communicate with the large
range of Metrohm titration and dosing instruments but it can also con-
trol or be controlled by a personal computer. For this purpose Metrohm
offers the versatile Tinet titration software. These capabilities predestine
it for all conceivable automation jobs in a modern laboratory, even in
conjunction with highly integrated laboratory data systems.
