A spectrophotometer is a measuring instrument that samples reflective or transmissive objects with discrete wavelengths. Due to the different molecular structures of different objects, the ability to absorb light of different wavelengths is also different. Therefore, each object has a specific absorption spectrum. A spectrophotometer separates each monochromatic light from a mixture of wavelengths and measures its intensity.

Spectrophotometer, also known as spectrometer, is a scientific instrument that decomposes light with complex components into spectral lines. The measurement range generally includes the visible light region with wavelengths ranging from 380 to 780 nm and the ultraviolet region with wavelengths ranging from 200 to 380 nm. Different light sources have their own unique emission spectrum, so different luminous bodies can be used as the light source of the instrument.

Colors surround us all the time and affect our emotions, behaviors and beliefs in conscious or unconscious ways. Colors can set emotions, warn us of danger, give us important information, and even bring us joy. Despite its ubiquity, description of color remains elusive, in part because different people perceive color differently. Two of the most advanced types of color measurement instruments are colorimeters and spectrophotometers, both of which use sophisticated technology to precisely quantify and define color. In this article, we will introduce the differences between colorimeter and spectrophotometer.

Today, we will introduce tips about the precautions and troubleshooting of the spectrophotometer. We hope that after reading this article, you can use the spectrophotometer more rationally, protect your spectrophotometer, and prolong the service life of the spectrometer.

UV spectrophotometer is a commonly used photometer product. With it, light of different wavelengths can be arbitrarily selected in the ultraviolet-visible region. The instrument has the advantages of stable performance, flexible use, high reliability, and easy maintenance. The UV spectrophotometer needs to be calibrated when in use. The following is the calibration method of the UV spectrophotometer.

Spectrophotometer is also called spectrometer, which is a scientific instrument that decomposes complex light into spectral lines. Using spectrophotometry, the spectrophotometer measures the absorbance of the measured substance at a specific wavelength or within a certain wavelength range to perform qualitative and quantitative analysis of the substance. The basic principles of different types of spectrophotometers are similar. They all use a light source that can generate multiple wavelengths, through a series of light splitting devices, to form a light source of a specific wavelength. After the light source passes through the test sample, part of the light source is absorbed. Subsequently, by measuring the absorbance of the sample, it can be converted into the concentration of the sample after calculation. The absorbance of the sample is proportional to the concentration of the sample.

1. Please don’t operate the visible spectrophotometer casually when you don’t know its performance deeply, operations shall be carried out under the guidance of operators skilled in the visible spectrophotometer.

2. Pay attention to sunscreen, anti drenching, damp proof and anti vibration. In case the visible spectrophotometer is dampened, put it in a cool and ventilated place, package after drying.
