DEVICE FOR ON-LINE MEASUREMENT OF NEUROTRANSMITTERS USING ENZYMATIC REACTORS

摘要

The invention relates to a device and a method for measuring neurotransmitters in the brain dialysate of mammals using enzymatic reactors specific to a certain neurotransmitter, which generate fluorescent derivatives when mixed. The mixture is introduced into an incubation chamber and passes through a temperature controlling system in order to set it to the optimum enzymatic reaction temperature, and the fluorescent derivative generated is passed through a flow fluorescence cell located inside the incubation chamber, where the liquid is impacted with a laser light source via an optical fibre. The fluorescence emitted is captured by a fluorescence detector that sends it to a processing system in order to obtain the corresponding values.
