Some common sense of the spectrometer

2018-10-11

A spectrometer absorbs energy of a specific wavelength of light by a specific functional group of an atom, a molecular plasma, and generates an energy level transition.At this time, if the intensity change of the light before and after absorption is called an absorption spectrometer, such as atomic absorption, ultraviolet visible absorption, infrared absorption, etc., if the light emitted by the energy level of the transition level after absorption is measured, the emission spectrum is called an emission spectrum.Tianmu Instrument Xiaobian brings you some tips on the spectrometer.

Mass spectrometers determine mass relationships and functional groups by breaking molecules into fragment ions and then detecting the charge-to-mass ratio.

Polarography determines the type and nature of ions by the diffusion rate of ions around a solution electrode at a certain voltage.,

After the light is incident, the collimator lens is collimated into the grating, and the light of different wavelength bands is separated, and then the focus spectrum is focused by the detector to receive the spectral information.

The focal length of the spectrometer: the focal length of the spectrometer is the focal length of the focusing mirror, referred to as the focal length.

General grating spectrometers have a 150mm focal length, 300mm focal length, 500mm, 750mm, and some manufacturers also have a 1 meter focal length spectrometer.

Under the same conditions, the longer the focal length, the higher the resolution of the spectrometer and the smaller the amount of light passing through.

Tianmu Instrument mainly produces spectrometers, welcome new and old customers to consult!
