Ion Selective Electrode for L- GlutamateA coated wire

Glutamate ( MSG ) ion selective electrode (ISE) was developed . Ag /Ag+Glu- wire electrode is covered by an inert silicon rubber and contact with reference electrode .The concentration range for which the glutamate ion can be detected , generally 10-4-1 M, with the calibration slop 26.4 mV decade -1 in 10 -2 M NaNO3 . The selectivity coefficient of (MSG) electrode were measured by separate solution method of some organic and inorganic compound . The electrode can be applied to determined MSG in milk by direct method . The temperature effect on (MSG) electrode behavior is described.
