DEVICE FOR POTENTIOMETRIC MEASUREMENTS Russian patent published in 2003 - IPC

FIELD: analyzers of composition of liquid media with use of ion-selective electrode. SUBSTANCE: device includes inlet flow lines linked to two reversers connected to manostats with throttles, two parallel branches for stabilization of sample parameters formed depending on purpose of analysis installed in manostats and across outlets of measurement cell comprising two intake chambers and chamber housing ion-selective electrode positioned between them. Control valve of reverser comes in the form of disc put on immobile shaft, L-shaped conduit for intake of flows is placed along radial axis of control valve and is connected to conduit feeding flow into manostat made along axis of shaft. EFFECT: raised productivity of analysis with use of multichannel liquid analyzer and expanded functional capabilities of device. 3 dwg
