Biochemical analyzer (BCA) is an analytical instrument used to measure various biochemical indicators of human blood. It can provide doctors and chemical laboratory personnel with testing data accurately and quickly, and plays an important role in monitoring bed diagnosis and chemical testing. The colorimeter is the core component of the biochemical analyzer. In traditional colorimeters, …
Important indicators of colorimeter For the colorimeter, there are several most important indicators which are wavelength repeatability, photometric accuracy and photometric repeatability. In the process of judging whether the instrument is normal or not, the above indicators will also be analyzed. ● Wavelength accuracy. In the process of analyzing the colorimeter, a very critical factor …

Details on the preparation of fully optimized instruments Before the colorimeter is used, relatively complicated preparations of other equipment, raw materials and conditions are required. This preparation stage plays a fundamental role in the operation and measurement of the caliber 4mm pocket colorimeter. The operator should first ensure the adaptability of the ring term during the …
The function of the colorimeter detector is to convert light of different intensities into electrical signals proportional to it, and then send the power to the star measuring instrument for processing. There are three types of photocells, photocells and photomultipliers. Among them, the most common is photocell, and the best performance is photomultiplier tube, colorimeter …

Influence of interference filter on verification optical path Since the wavelength peak of the interference filter changes with the incident angle, it must be ensured that the detection is completed at the angle of normal incidence of parallel light. At the same time, the interference filter must be properly used and maintained, and it must …
The colorimeter is an essential analytical instrument in drug analysis. We now give some suggestions to the operator on the problems encountered in the installation, debugging, maintenance, and testing of the instrument. Issues that should be noted Linearity of instrument photometric It is well known that light absorption analysis must conform to the linear relationship of …
Photometric accuracy refers to the deviation between the transmittance (absorbance) read by the instrument on the absorption peak value and the known true transmittance (absorbance). Photometric repeatability refers to the operator repeatedly measuring certain repeatability of the transmittance (absorbance) of an absorption peak. The photometric accuracy of the portable colorimeter varies with the instrument and the …

Ideas and methods to eliminate unstable faults The Colorimeter is one of the common analytical instruments and is widely used. Instability of indication value is also a common fault encountered by instrument users and testing personnel. For the colorimeter, “instability of the indication value” means that after the instrument is fully warmed up, the maximum …
