potassium ferricyanide sigma

Chemiluminescence flow sensor with immobilized reagent

Pyrogallol was sensed by the CL reaction between pyrogallol and potassium hexacyanoferrate(III) which was eluted from the ion-exchange column through sodium phosphate injection The CL emission allows quantitation of pyrogallol concentration in the range 0 01-3 8 microg/mL with a detection limit (3 sigma) of 0 003 microg/mL and a sample throughput of 118 h(-1) The relative standard deviation
