Overview
The LICHEN WGH6420 smart Flame photometer is an analytical instrument based on the principle of emission Light spectrum, which is mainly used for quantitative analysis of alkaline metal elements within a certain concentration range. The instrument excites the atoms of the measured element to emit light by flame and detects its Light spectrum energy intensity to determine the content of specific elements in the substance. It integrates gas combustion, Optical inspection system, photoelectric conversion and detection recording.

Principle
The Flame photometer works on the principle of emitting Light spectrum. The thermal energy of a flame is used to excite the atoms of an element in the sample to a high energy state, and when these atoms return to the ground state, they emit a specific wavelength of Light spectrum. The instrument collects these optical signals through an Optical inspection system, converts them into electrical signals by a photoelectric converter, and finally analyzes the strength of the signal by detecting the recording part to quantitatively determine the content of the element in the substance. Due to the limitation of flame excitation energy, this instrument is mainly suitable for quantitative analysis of alkaline metals.
Applications
Quantitative analysis of alkaline metal elements
Steps
1. Instrument preparation and startup
