چکیده

A multi-channel continuous-flow ana]yzer equipped with biosensing deyices was deyeloped for multicomponent measurement and its use in automating routine analysis was evaluated. Biosensing was achieyed by the aid of an immobilized enzyme reactor insta]led in the channel, and the channe] switching process for the sensing of a different compound was made by using a column-switching rotary valve. Another rotary yalve was used for auto-sampling. Both of the two rotary valves were interfaced to a system control}er and work conjugatively in a programmed manner. Signal subtraction between different channels was found to be more precise compared with the multi-channel flow-injection analysis method,
