Problems solved by technology

Quadrupole setups use four electrode rods and provide better mass discrimination than hexapole or octopole setups, but less efficient ion transmission than hexapole or octopole setups
Therefore, the collision cell or collision cell using the multi-stage rod device cannot have both high-quality mass discrimination effect and strong ion transmission efficiency, and this kind of collision cell or collision cell does not have the focusing function for ions, which affects the analysis results. accuracy

Abstract

The invention discloses a collision reaction cell, which includes a cavity body and an ion funnel; the cavity body has a first end and a second end, the first end and the second end are respectively provided with an ion inlet and an ion outlet, and the cavity body is provided with a gas The inlet is used to fill the cavity with reactive gas; the ion funnel is located inside the cavity, including multiple lenses arranged in parallel at intervals, each lens is provided with an opening, and the multiple openings, ion inlet and ion outlet are in total line for the passage of ions, and the aperture of each lens is less than or equal to the aperture of the adjacent lens near the ion inlet side; wherein, each lens is applied with a DC voltage, and each lens is applied with DC voltage, less than the DC voltage applied to the adjacent lens on the ion entrance side. The invention has better mass discrimination effect and stronger ion transmission efficiency. At the same time, through the setting of multiple lenses, the collision reaction cell is further equipped with the function of focusing on ions.

Description

technical field [0001] The invention relates to the technical field of element analysis, in particular to a collision reaction cell based on inductively coupled plasma quadrupole mass spectrometry technology. Background technique [0002] In the field of elemental analysis, ICP-MS (Inductively coupled plasma mass spectrometry) technology has developed rapidly in recent years and is widely used in geology, high-purity materials, nuclear industry, biology, medicine, metallurgy, petroleum, agriculture, It is currently recognized as the most powerful elemental analysis technique in the fields of food and chemometrics. [0003] When using ICP-MS to determine trace elements or isotope ratios, polyatomic ions, neutral molecules and photons entering the mass spectrometer will affect the accuracy of the analysis results. Since the advent of ICP-MS, various studies have been devoted to overcoming this problem. In addition to the commonly used mathematical correction methods, techniq...
