Miniaturization of a liquid membrane sensor for the determination of bile acids.
The preparation of a compound liquid ion exchanger used for the miniaturization of bile acid sensitive microelectrode is described. The liquid ion exchanger is 2% benzyldimethylhexadecylammonium cholate in decanol/0.1 M hexadecyltributylammonium taurocholate in 5% hexachlorobenzene, 0.5% bromoacetanilide O-dichlorobenzene. The slopes, detection limits, selectivity coefficients, drifts and response time of the various bile acid sensitive microelectrodes are evaluated and compared.
