Electrolytes Electrode Filling Solutions

Lipophilic ionophore for Ca²⁺ selective electrodes with detection limit in the sub-nanomolar range.


Extremely efficient carrier of Ca²⁺ -ions; induces a selectivity in membranes for Ca²⁺ over Mg²⁺ by a factor of about 10⁴. Calcium ionophore II (ETH 129) was used in preparing calcium selective minielectrodes which are used in determination of dissociation constant (Kd).


Packaging: Packed in bottomless glass bottle. Contents are inside inserted fused cone.
