Enzyme standard instrument
Enzyme standard instrument is actually a disguised form of special photoelectric colorimeter or spectrophotometer, its basic working principle and main structure and photoelectric colorimeter are basically the same. Here is a kind of single channel enzyme standard instrument working principle of automatic sample figure. Light from the light source lamp by the filter or become a beam of monochromatic light monochromator, into plastic micro hole in the specimen under test. Part of the monochromatic light is absorbed by the specimen, and specimens of others through exposure to the photoelectric detector, photoelectric detector to the specimen under test of strength varied convert optical signals into corresponding electrical signal.
Electrical signal by the preamplifier, logarithmic amplifier, adc and signal processing after the detail processor for data processing and calculation, at last shows the result by the display and printer. Microprocessor is also by control circuit to control the machine drive X direction and Y direction of the movement to move the MPP, so as to realize automatic sampling inspection process. And some other enzyme standard instrument is manually moving MPP for testing, thus eliminating the X, Y direction of the mechanical drive and control circuit, so that the instrument is smaller, the structure is simpler.
MPP is a kind of advanced package manager dedicated to place a transparent plastic sheet of the sample under test, on board how size uniform holes, hole is embedding the corresponding antigen or antibody, each holes can be contained in the MPP tenths of ml solution.
Light is electromagnetic wave, the wavelength of 100 nm to 100 nm is called the uv light, light can be between 400 nm to 780 nm eye observes, greater than 780 nm called infrared light. People only so can see colour, because light to the object are reflected by the object. Green plants are green, because most of the plants absorb for red and orange light and LanZiGuang, but the green is not absorbed, reflected, so the render for the green plants. Standard measuring principle of the enzyme is under a particular wavelength, the absorbance value of the analyte detection.
