摘要

#CMT# #/CMT# The multi-parameter electrode has a variable number of pipe segments made of ion selective glass with identical expansion coefficients. The pipe segments are integrated in a tube of optional length made of laboratory glass such that a sufficiently large section of chemically inert laboratory glass is always located between the segments, which are covered in overlapping manner. #CMT#USE : #/CMT# Multi-parameter electrode for simultaneous potentiometric determination of activities of different cations in aqueous medium. #CMT#ADVANTAGE : #/CMT# The multi-parameter electrode has a variable number of pipe segments made of ion selective glass with identical expansion coefficients, and hence ensures an optimal stability of the half cell potentials and reproducibility of the absolute values of these potentials with multiple homogenously prepared multi-parameter electrodes. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of multi-parameter electrode for determining hydrogen ion concentration value and potassium and sodium ion activity. 1 : Thuringian laboratory glass 2 : Hydrogen ion concentration glass 3 : Potassium-selective glass 4 : Sodium-selective glass 6 : Nickel layer #CMT#INORGANIC CHEMISTRY : #/CMT# The multi-electrode function determines glass around selective glasses for acting on hydronium ion, sodium ion, potassium ion, silver ion, rubidium ion, cesium ion, ammonia ion, calcium ion, barium ion, strontium ion and magnesium ion. The zinc oxide layer with a covering nickel-phosphorus layer has phosphorus content.
