With the research and development of the methodology and instruments of laboratory medicine, the means of medical examination have been developed from a single optical microscope in the past to an automatic and semi-automatic inspection and analysis instrument. Biochemical examination and separation instruments are the main components of medical examination instruments, is a combination of physics, chemistry, optics and biomedical products,Bio-chemical Analyzer mainly including spectrophotometer, automatic biochemical analyzer, ultraviolet, visible light photometer, fluorescence spectrophotometer, and its structure is mainly optical system (optical path) and circuit system (circuit) two components. In order to make the instrument often in good working condition, the equipment should be regularly maintained and maintained.
Grating is the main dispersion component of the continuous spectrum analysis instrument. Because of its uniform dispersion, clear spectral line and wide working band, it has basically replaced the prism and become the main character of the dispersion element. The grating is an optical element composed of many equal-width and equidistant parallel slits, which are based on the diffraction of light and the principle of dry-shoot. Its surface is plated with a layer of aluminum film, texture soft, easily scratched. Therefore, in the maintenance, repair process, lightly take care,Bio-chemical Analyzer prohibit the use of hands or other items to wipe. Otherwise, the aluminum film will cause permanent damage. If there is dust on the aluminum film and other unclean things. You can blow it with a blow balloon.
The collimating mirror is actually a concave. is based on the nature of the concave, which is parallel to the spindle of the near-axis light, after concave reflection will converge on the focal plane of the principle of work. Most of the collimating mirrors are spherical mirrors and rotating parabolic mirrors. The surface of the collimating mirror is usually coated with an aluminum film, if in the visible area,Bio-chemical Analyzer in order to protect the aluminum film from damage, often in the aluminum coating outside the coating of a layer of silica, but in the ultraviolet area, in order to ensure a higher reflectivity, generally no such protective layer, for no protection of the collimating mirror, its maintenance method and the same grating. It is forbidden to wipe with hand or other hard objects during maintenance and repair.
The colorimetric dish is also called a colorimetric tank, a colorimetric cup, a colorimetric groove, etc., which is an accessory of biochemical analyzer. The colorimetric dish is mainly used in the optical system to hold the sample solution in the colorimetric analysis. In order to obtain higher accuracy measurement results, the proper use and maintenance and maintenance of the colorimetric dishes are particularly important. In the visible range, the colorimetric dish is usually made of colorless optical glass or plastic; In addition to having light transmittance, the colorimetric dish should have strong corrosion resistance. Colorimetric dishes and instruments are compatible, can not be mixed, otherwise it will bring greater measurement error. The method of checking whether a colorimetric dish meets the requirements is to put the same coloured solution in each colorimetric dish,Bio-chemical Analyzer measured at the specified wavelength, and the transmission ratio error should be less than 5}. Otherwise, the error is too large and should not be used. When using a colorimetric dish, you should pay attention to the direction of its placement, because the light transmittance of the direction of light, the ability of its transmission may change. Some of the color dishes on the front of the table, used to indicate the direction of light. When the liquid is put in place,Bio-chemical Analyzer the liquid quantity is slightly more than the I/2 of the Color Cup, and the liquid or other sundries can not be adhered to on the outside of the color dish. Otherwise, the result of the measurement will be seriously affected by the reflection and refraction of light. At the end of the measurement, the person should be immediately flushed in distilled water, regularly inspected for residues and kept clean.
The eyepiece and objective lens are the main components of an optical microscope. As a simple optical inspection instrument, optical microscope is widely used in large and small hospitals because of its simple structure and convenient operation. In order to maintain its performance and prolong its life, it needs to be maintained and serviced frequently. First of all, the eyepiece, lens lens surface in each use or one day after the end of work, need to clean brush, or with a special mirror wipe clean. If the microscope has blurred vision,Bio-chemical Analyzer or the lens is not touched by dirt, oil or finger print. Or the lens of mildew, raw fog, should be more serious by engineering and technical personnel wipe: When wiping, the eyepiece, concentrating through can be broken apart to wipe. Objective lens because of complex structure, need special instrument to correct to restore the original accuracy, so it is strictly prohibited to decompose and wipe.
