摘要：NOVELTY - The utility model claims a mass spectrometry device ionization source by using microwave plasma torch, a microwave plasma torch tube is obliquely set on the vertical plane of the ion transport tube of the spectrum scanner, opening end of the torch tube downward and entrance towards the ion transmission tube. inclined angle between the tube and the horizontal plane is 30 degrees, the tube opening end generating torch, horizontal vertical distance of torch tip and the sample carrier is about 3 mm, and ion transmission tube entrance is about 12 mm, such that the torch to desorb the liquid sample in the sample carrier is obtained by product ions can smoothly enter the ion transmission tube entrance. the mass spectrometric analysis. The utility model of the mass spectrometry device has simple structure, is convenient to build, without sample pre-treatment, directly desorbing the liquid sample, ionization efficiency, fast analysis speed, ionization analysis sample consumption, low analysis cost, which is very suitable for high cost or rare samples.
