Enzyme mark instrument is actually a disguised form of special photoelectric colorimeter or spectrophotometer, the basic working principle and main structure and photoelectric colorimeter is basically the same. This is a single channel automatic feeding enzyme sign meter working principle diagram. The light source lamp emits light into a beam by filter or monochromator monochromatic light, into the plastics microporous pole in the middle of a sample to be tested. The monochromatic light is absorbed part of a specimen, the other part passing through the specimen is irradiated to the photoelectric detector, photoelectric detector and the sample to be tested is different and different intensities of light signal is converted to a corresponding electrical signal. Signal through a preamplifier, a logarithmic amplification, analog-digital conversion and other signal processing evacuation into the processor for data processing and calculation, finally by the monitor and printer to display the results. The microprocessor is controlled by the control circuit of mechanical drive mechanism X direction and the Y direction of motion to move the microtiter plate, so as to realize the automatic sampling detection process and some other enzyme mark instrument is used to manually move a microtiter plate were detected, thereby eliminating the X, Y enzyme mark instrument orientation of mechanical drive mechanism and a control circuit, so that the apparatus is more compact, more simple structure.

The enzyme mark instrument used by the narrow band filter with 340nm, 405nm, 505nm, 546nm, 578nm, 630nm and 670nm these bands, bandwidth requirements in the 8-10nm, the depth required high.

My company produces the enzyme mark instrument filter, using plywood production process, its characteristic is the center wavelength of accurate positioning, high precision positioning by depth, to monochromatic light, prevent the interference of light into the.
