Description
Technical Field
The utility model belongs to the technical field of the semiconductor, a survey needle-like sample's carrier is related to, concretely relates to indium carrier that is used for glow discharge mass spectrograph survey needle-like sample.
Background
Glow Discharge Mass Spectrometry (GDMS) is an analysis method for Mass Spectrometry by using a Glow Discharge source as an ion source and connecting the Glow Discharge source with a Mass spectrometer, and is mainly used for detecting the content of trace elements in materials, and the corresponding analysis instrument is called a Glow Discharge Mass spectrometer. One of the core components of the glow discharge mass spectrometer is a glow discharge chamber, which is used for glow discharge of a sample to be detected and ionization into ion beams after neutral particles are sputtered. Aiming at the shape and size of a sample to be detected, the glow discharge chamber is divided into a sheet-shaped glow discharge chamber and a needle-shaped glow discharge chamber, wherein the size requirement of the sheet-shaped glow discharge chamber on the sheet-shaped sample to be detected is generally 20mm multiplied by 2mm, and the size requirement of the needle-shaped glow discharge chamber on the needle-shaped sample to be detected is generally 20mm multiplied by 2 mm. However, in the actual production, processing and use processes, the sample to be tested has various forms, including irregular block, powder, granule, chip, needle and the like, and cannot be effectively fixed by the sample clamp in the glow discharge chamber, which seriously hinders the GDMS analysis.
Aiming at the problem that a fine sample to be detected cannot be effectively fixed by a sample clamp in a glow discharge mass spectrometer, the prior art discloses a plurality of novel sample loading parts to be detected. For example, CN205374369U discloses a loading device for measuring powder samples by a glow discharge mass spectrometer, which includes a base, on which four vertical faces are disposed, wherein two vertical faces are parallel and oppositely arranged planes, and the other two vertical faces are circular arc faces for connecting the two planes; the center of base top surface sets up a through-hole detachably connects an elastic gasket in the through-hole, the diameter of gasket through-hole is 10 ~ 15 millimeters. Although the loading device can reduce the using amount of the powder sample, improve the pressing strength of the powder sample, and quickly and conveniently measure the powder sample by using the glow discharge mass spectrometer, the loading device is not suitable for glow discharge mass spectrometers of all models, greatly increases the instrument cost, and is not suitable for large-scale popularization.
CN210923569U discloses a sample table for testing small-size samples by a glow discharge mass spectrometer with the model number of ELEMENT GD, which consists of a high-purity copper sample table body and soldering tin, wherein a groove is formed in the high-purity copper sample table body, and the soldering tin is arranged in the groove; the diameter of the surface of the high-purity copper sample table body is 25 mm-50 mm, and the height is 5 mm-20 mm; the groove is a cylindrical groove, the diameter is more than 20mm, and the depth is more than or equal to 3 mm. The sample platform is provided with the groove through the high-purity copper body, and the proper amount of soldering tin is placed in the groove, so that a small-size sample can be fixed on the high-purity copper sample, the soldering tin can not expose the lower surface of the sample, and the influence of the soldering tin on the sample during testing is avoided.
In order to better analyze samples to be tested with various shapes and sizes by using GDMS, researchers improve and optimize the sample preparation method and develop a pressing method and a tantalum slot method. The pressing method is that a fine sample to be detected and conductive powder are uniformly mixed and then pressed into a sheet or a needle shape with qualified size through a special mold, and then the sheet or the needle shape is analyzed in a corresponding glow discharge chamber and is commonly used for powdery, granular and chip samples to be detected. The tantalum slot method is that a tantalum carrier with a sample slot is manufactured according to the size requirement of a sample feeding device, and a tiny sample to be tested is put into the sample slot for analysis.
However, if a pressing method is adopted for preparing a sample to be measured, fine needle-shaped samples are easy to introduce impurities, the accuracy of a measurement result is seriously influenced due to the problem of uneven mixing with conductive powder, and the method is not suitable for samples with low viscosity; if adopt the tantalum groove method to make appearance, not only cause the measurable area reduction of the sample that awaits measuring, reduce signal strength for the detection limit variation still can not be fixed because the sample that awaits measuring in the sample groove, drops from the sample groove easily, seriously influences detection speed, in addition, opens the tantalum carrier that has the sample groove and need customize, can't adjust again after the customization, greatly increased detection cost.
In view of the above, there is a need to develop an indium carrier for a glow discharge mass spectrometer to measure a needle-shaped sample, which can make a fine needle-shaped sample to be measured into a size that can be detected by GDMS without introducing impurities.
