The invention relates to the field of analytical instruments and especially relates to an infrared spectrometer. The infrared spectrometer comprises a light source, an absorbing cell, a monochromator, a detector, a computer processing information system and an automatic feeding system, wherein the automatic feeding system comprises a feeding port, a potassium bromide quantitative sample injector, a grinding stirring chamber, a drying chamber, a pre-forming chamber and a conveyor belt; the automatic feeding system and a vacuum pump are adopted, so that the detection system of the infrared spectrometer is under a water-free and carbon dioxide-free state, the interference of water and carbon dioxide to the infrared spectroscopy of the sample is reduced and the sensitivity and accuracy of the infrared spectrum detection are promoted; and an automatic pre-forming grinding component and the conveyor belt are combined for feeding the sample, so that the problems that the infrared sample sheet is difficult to de-mold and is easy to break in the process of transferring to a sample chamber in the prior art can be solved and the operation is convenient and quick. |
