features • Species diffuse through dialysis tube into clean buffer • Flow injection analysis: clean background • Highly sensitive enzyme-based analysis
linear response to hydrogen peroxide is observed in the concentration range 5 x 10-8 – 6 x 10-6M.
Low concentrations of ferrocene in the buffer Primary reaction on oxidase enzyme is therefore with oxygen Efficient conversion in a packed bed of enzymes Flow injection analysis gives high sensitivity on a clean background
Fig. 5. (A) A 2 h period of on-line monitoring of glucose (black) and lactate (grey) present in dialysate, from a probe implanted in the brain of a patient in the neurointensive care unit. Data recorded every 3 min. (B) A 2 h period of on-line monitoring of glucose (black) and lactate (grey) present in dialysate, from a probe implanted in the brain of a patient during surgery to clip an aneurysm. Data recorded every 30 s.
