What indicators can be measured by UV VIS spectrophotometer?
Ultraviolet visible spectrophotometry: a qualitative, quantitative and structural analysis method based on the absorption characteristics of electromagnetic wave in the range of 200-760nm.
In fact, the fundamental principle is the same as that of an ordinary spectrophotometer. Why is the double channel set because one of the channels is empty white, or reference?. The operation time, the first is the two cuvette filled with blank solution, with one reference zero, then take another cuvette, note reading, this is the absorbency of blank value corresponding to the 0, which is due to the error caused by the different cuvette, drawing in time is to account for the. Then, replace the blank solution in the cuvette, which is considered a sample, into a true sample and measure its absorbance.
What indicators can be measured by UV VIS spectrophotometer?
Each material has its unique and fixed absorption curve, according to the absorption spectra of some characteristic wavelength absorbance level determination of the substance or discrimination, and this is divided into qualitative and quantitative analysis of spectrophotometry. Therefore, the principle can be applied and the spectrum of ultraviolet visible spectrophotometer can be detected by ultraviolet visible spectrophotometer.
The following are common:
Drug analysis: drugs can be detected by ultraviolet visible spectrophotometry, suitable for drug inspection, drug analysis, pharmaceutical and other industries. Life science: the concentration of DNA and protein.
Agriculture and Fishery: detection, crop composition detection, detection, detection of veterinary drug feed and fertilizer test, soil composition detection, detection of pesticide residues in aquaculture. Geological prospecting: Determination of metallic and inorganic salts in ores.
Food safety: additives, preservatives, spices, fats, enzymes, sugars, spices, minerals, vitamins and so on.
Environmental monitoring: monitoring of water quality, atmosphere, rainfall and soil, and measuring the contents of various pollutants.
