Quotation for UV spectrophotometer

UV spectrophotometer is a type of optical instrument that can be widely used in various fields such as medical and health, chemical engineering, environmental protection, geology, machinery, metallurgy, petroleum, food, biology, materials, metrology science, agriculture, forestry, fisheries, etc. It is used for qualitative analysis, purity inspection, structural analysis, determination of complex composition and stability constants, reaction kinetics research, etc.

　　

Characteristics of UV spectrophotometer:

　　

(1) No need for sample separation device. Since spectrophotometry uses high-purity monochromatic light, when using this method to determine the presence of two or more sample components, there is no need to perform sample separation treatment first. Only monochromatic light with characteristic wavelengths of the sample components can be selected for measurement and analysis.

　　

(2) There are multiple quantitative methods, including spectrophotometry, which can not only be quantified using linear regression, but also directly quantified using the formula for converting the percentage extinction coefficient to the molar extinction coefficient. Therefore, spectrophotometry is more effective than colorimetric methods in terms of quantitative methods.

　　

Product features

　　

● Luminescence measurement: convenient for measuring the absorbance and transmittance of samples at wavelengths. Multi wavelength fixed-point testing can simultaneously measure 10 wavelengths;

　　

Quantitative measurement: Automatically establish standard curves, fit first-order/first-order zero crossing, second-order, and third-order curves, with optional single wavelength correction, dual wavelength correction, and three-point method;

　　

Qualitative measurement: Graph processing methods include scaling, smoothing, filtering, peak valley detection, etc;

　　

Dynamics measurement: Enzyme kinetics reaction rate calculation. Multiple spectral processing methods such as scaling, smoothing, filtering, peak valley detection, and differentiation are available for you to choose from;

　　

DNARNA, protein testing function, automatic calculation of sample ratio and concentration.

　　

Maintenance of UV spectrophotometer:

　　

1. Dust and corrosive gases in the environment can affect the flexibility of mechanical systems, reduce the reliability of various limit switches, buttons, and photoelectric couplings, and are one of the reasons for the corrosion of aluminum films on essential components. Therefore, it is necessary to regularly clean, ensure the hygiene conditions of the environment and instrument room, and pay attention to dust prevention.

　　

2. After a certain period of use, a certain amount of dust will accumulate inside the instrument. It is recommended to have a maintenance engineer or under the guidance of an engineer regularly open the instrument cover to remove dust from the inside. At the same time, the heat sinks of each heating element should be re tightened, the sealing window of the optical box should be cleaned, and if necessary, the optical path should be calibrated. The mechanical parts should be cleaned and lubricated, and then restored to their original state. Necessary testing, calibration, and recording should also be carried out.
