Three-dimensional mobile platform and ICP torch tube positioning device applied therewith

Abstract

The invention provides a three-dimensional mobile platform which is composed of an X-direction mobile station, a Y-direction mobile station and a Z-direction mobile station which are mutually independent and are correspondingly in X direction, Y direction and Z direction respectively, wherein the X-direction mobile station and the Y-direction mobile station are same in structure and form a cross-shaped structure together; and the X-direction mobile station is arranged on the bottom, the Y-direction mobile station is arranged on the X-direction mobile station and the Z-direction mobile station is arranged on the top. The invention also provides an ICP torch tube positioning device which comprises the three-dimensional mobile platform and an ICP light source generation apparatus, wherein the ICP light source generation apparatus is arranged on a bearing platform of the Z-direction mobile station of the three-dimensional mobile platform. The ICP light source generation apparatus comprises a torch tube, a torch tube clamp seat, an RF coil and a high frequency generator, wherein the torch tube clamp seat is fixedly arranged on the bearing platform; the torch tube is arranged inside the RF coil; and the two ends of the RF coil are in threaded connection with the copper joints of the high frequency generator respectively. The beneficial effects are that: the three-dimensional mobile platform is stable in operation and precise in positioning; the three-dimensional mobile platform is applied to the ICP torch tube positioning device, so that repeated accurate positioning of the torch tube is realized, three-dimensional mobile platform and the ICP torch tube positioning device are structured compactly and highly-reliable.

Description

technical field [0001] The invention relates to the field of micro-motion equipment, in particular to a three-dimensional mobile platform and an ICP torch positioning device using the same, which can be widely used in the clamping and moving of the torch in ICP analysis instruments. Background technique [0002] In modern analytical testing instruments, inductively coupled plasma (ICP) spectrometer is an important analytical equipment widely used in resources, environment, medicine, food and other fields, such as ICP-MS, ICP-AES (OES) are some sophisticated analysis The common working principle of the test instruments is: the ICP torch atomizes the elements, and the generated fluorescence is detected by the corresponding photomultiplier tube. After the photoelectric conversion, the electrical signal is amplified and processed by the computer, and the element analysis result is reported. The main factors affecting the precision and accuracy of ICP spectral analysis are: inter...
