Introduction

A Spectrophotometer is a commonly used laboratory instrument that measures the ability of a substance to absorb, transmit, or reflect light at different wavelengths. It determines the concentration or optical properties of a sample by how well the light emitted by the light source is absorbed through the sample. Spectrophotometers are widely used in chemistry, biology, environmental science, and other fields, and are an important tool for quantitative analysis, quality control, and research.

Introduction to the structure of the instrument

The working principle of a Spectrophotometer is based on the Bill-Lambert law, which states that the absorption of light is directly proportional to the concentration of the sample.

It usually consists of the following main parts:

Light source:Spectrophotometers typically use visible or ultraviolet light sources, such as incandescent, halogen, or deuterium lamps. The light emitted by the light source is selected by a selection device to select a specific wavelength of light.

Monochromator:The monochromator is used to select and adjust the desired wavelength. It can be a prism or grating structure that separates multiple wavelengths of light and selects a specific wavelength by the principle of dispersion.

Sample Chamber:The sample chamber is the area where the sample to be tested is placed. Samples can be liquid, gaseous, or solid samples. As light passes through a sample, its intensity is affected by the absorption or transmission of the sample.

Photoelectric Sensors:Photosensors are used to measure the intensity of light after passing through a sample. It converts light energy into an electrical signal, and the degree of absorption of light is determined based on the magnitude of the electrical signal.

Inspection systems and data processing:Spectrophotometers are usually equipped with a detection system and data processing capabilities. These functions can include light intensity measurements, wavelength calibration, data logging and analysis, and more.

By selecting the appropriate wavelength, calibrating the instrument, measuring the absorbance or transmittance of the sample, a Spectrophotometer can be used to measure the concentration of the sample, reaction kinetics, solution equilibrium, spectral analysis, and more. It can also perform quantitative analyses, such as constructing standard curves to determine the concentration of unknown samples.
