Abstract
Description
Technical Field
[0001] This invention belongs to the field of inductively coupled plasma mass spectrometry (ICP-MS) technology, specifically relating to a precision interface cone component, its preparation method, and its application. Background Technology
[0002] Inductively coupled plasma mass spectrometry (ICP-MS) is an inorganic element and isotope analysis technique developed in the 1980s. It combines the high-temperature ionization characteristics of inductively coupled plasma with the sensitive and rapid scanning advantages of mass spectrometry through a unique interface device, resulting in a highly sensitive analytical technique. ICP-MS mainly consists of three parts: an ICP source, an interface device, and a mass spectrometry analysis module. The interface cone is the main component of the interface device, typically composed of a sampling cone and a cutoff cone. The interface cone plays a crucial role in the ion current transmission efficiency, greatly affecting sensitivity and directly determining the instrument's detection limit and stability. The interface cone operates in harsh environments, at high temperatures (approximately 7000K) and in acidic or alkaline conditions; therefore, it must meet requirements for high temperature resistance, corrosion resistance, and good thermal conductivity.
[0003] US Patent 5793039A discloses a mass spectrometer, a slug assembly, a slug, and a method for manufacturing the same. The cone is manufactured using compression molding, a method significantly easier than machining, thus reducing production costs.
[0004] Patent GB2470288A discloses an improved method for preparing mass spectrometer sampling cones, where conventional cone apertures can be affected by increased surface contamination. Ion-implanted transition metals (especially titanium) provide a more robust and less reactive surface, thus requiring less cleaning to maintain high performance.
[0005] Patent WO2018163576A1 discloses a plasma cone for an inductively coupled plasma mass spectrometer (ICP-MS), an ICP-MS, and a method for manufacturing the plasma cone for an ICP-MS. A thin film of platinum, platinum group metals other than platinum, gold, or their alloys is deposited on the surface of the plasma cone using various coating methods. This invention can reduce impurity background without sacrificing sensitivity (ionic strength), further improving cone durability.
[0006] Patent CN2510862Y discloses an inductively coupled plasma mass spectrometry interface device, which consists of a sampling cone and a snipping cone. The sampling cone and the snipping cone are axially concentric. The thickness of the cone hole end of the sampling cone and the snipping cone is 0.2mm to 0.5mm, and they are made of corrosion-resistant and high-temperature resistant metal materials.
[0007] Existing patents rarely involve the manufacturing process of interface cone components. Interface cone components manufactured by traditional molding or machining processes are difficult to design with multi-material composite structures, have difficulty to be used for a long time in high-temperature and corrosive working environments, and have complex manufacturing processes and high production costs. Summary of the Invention
