Problems solved by technology

However, there is no improved design for the argon gas circuit. The argon gas circuit does not have a pressure changing device, and the gas circuit does not have a forced blowing function. A relatively simple argon gas circuit board is still used.

Abstract

The invention provides an argon excitation system of a spectrograph. The argon excitation system comprises a strong blowing air channel, a main air channel, a side air channel, a public air channel and a shutter control air channel, wherein all the air channels are arranged on an integrated air channel plate of the argon excitation system of the spectrograph; an air source is arranged at an airstream inlet of the strong blowing air channel, and an airstream outlet of the strong blowing air channel serves as a first air outlet; the air source is arranged at an airstream inlet of the public air channel and is connected with the shutter control air channel, an airstream inlet of the main air channel is formed in the public air channel and is provided with an argon meter, and an airstream outlet of the main air channel serves as the first air outlet; an airstream inlet of the side air channel is formed in the public air channel, and an airstream outlet of the side air channel serves as a second air outlet; the airstream outlet of the shutter control air channel serves as a third air outlet; the air channels are respectively at least provided with an electromagnetic valve. The argon excitation system provided by the invention has the advantages that the pressure is changed, design of different air channels is available, the gas tightness is good, and the precision of the argon excitation system is improved.

Description

technical field [0001] The invention relates to a gas path system, in particular to a gas path system of a spectrometer. Background technique [0002] The photoelectric direct reading spectrometer is an emission spectrometer, which is mainly used to quantitatively analyze the sample by measuring the intensity of the characteristic spectrum representing each element when the sample is excited. At present, both domestic and foreign photoelectric direct reading spectrometers can basically be divided into 4 modules according to their functions. 1. Excitation system: the task is to fully atomize solid samples through various methods and release the emission spectrum light of each element. 2. Optical system: process (organize, separate, screen, capture) complex optical signals generated by the excitation system. 3. Measurement and control system: measure the characteristic spectral line intensity representing each element, and convert the light intensity signal of the spectral li...
