Waste liquid collection device for mass spectrometer

Abstract

The invention discloses a waste liquid collection device for a mass spectrometer. The device comprises a transfer barrel, a feeding device is arranged at the right end of the upper surface of the transfer barrel, and a single-way valve is arranged at the junction of a conveying pipe and the transfer barrel of the feeding device; a ventilation pipe is arranged in the middle of the upper surface ofthe transfer barrel, an air pressure adjustment device is arranged at the upper end of the ventilation pipe, and a pipe opening of the lower end of a tee pipe of the air pressure adjustment device isfixedly connected with the ventilation pipe; a switch unit is arranged on the side face of the transfer barrel, an input end of the switch unit is electrically connected with an output end of an external power supply, a discharging pipe is arranged on the lower surface of the transfer barrel, and a first manual valve is arranged on the side face of the discharging pipe. The waste liquid collectiondevice for the mass spectrometer can extract, convey and collect waste liquid, redundant waste liquid can be transferred and stored, gas in the transfer barrel and a storage barrel can be discharged,the storage amount of waste liquid in the storage barrel can be increased, and the device is easy to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of mass spectrometers, in particular to a mass spectrometer waste liquid collection device. Background technique [0002] A mass spectrometer is also called a mass spectrometer. An instrument for separating and detecting different isotopes. That is, according to the principle that charged particles can be deflected in an electromagnetic field, a type of instrument is used to separate and detect material composition according to the mass difference of material atoms, molecules or molecular fragments. Mass spectrometers are divided into isotope mass spectrometers, inorganic mass spectrometers and organic mass spectrometers according to their application scope. According to the resolving power, it is divided into high-resolution, medium-resolution and low-resolution mass spectrometers; according to the working principle, it is divided into static instruments and dynamic instruments. In the process of liquid ...

AI Technical Summary

Problems solved by technology

In the process of liquid phase sampling, the amount of liquid phase sample added will be relatively large. In order to avoid damage to the mass spectrometer due to excessive liquid phase samples, the excessive liquid phase is generally introduced into the drain through the switching pipeline. In the liquid pipeline, it is discharged into the waste liquid collection bottle through the liquid discharge line. The existing waste liquid collection bottle is only composed of an ordinary bottle, which cannot discharge the gas in the waste liquid, and reduces the volume of the waste liquid collection bottle. , and when there is a lot of waste liquid, the waste liquid inside the collection bottle cannot be cleaned in time, which is inconvenient to use
