Description

​HDOPP-Ca is a liquid cation exchanger for use in the calcium ion selective electrode. HDOPP is the most suitable compound among the dialkyl phosphate derivatives, and is used in either a liquid membrane or a PVC membrane using DOPP (dioctylphenylphosphate calcium salt) as a plasticizer.
