Abstract
The utility model discloses a rapid sample introduction device which is used to analyze solid samples in microvacuum, and comprises a small scale auxiliary vacuum chamber 5 which is arranged in a microvacuum cavity 12, and a direct insert type and rotary sample introduction rod 2 which inserts into the auxiliary vacuum chamber 5 and the microvacuum cavity 12. A relative vacuum gap exists between the auxiliary vacuum chamber 5 and the microvacuum cavity 12; therefore, when the ample introduction rod 2 enters or come out of the microvacuum cavity 12, the vacuum degree in the microvacuum cavity 12 is hardly influenced, which enables the analysis of solid samples to be time-saving and labor-saving. The rapid sample introduction device of the utility model is simple-structured, convenient and flexible, can be used in any microvacuum equipments to analyze solid samples or to replace and analyze solid samples. The analysis process only needs a plurality of minutes and does not need halt the machine. The utility model is in particular suitable to analyze solid samples or the organic contaminating material which deposits on the surface of the solid samples in laser mass spectrometry or in ion emission spectrum such as laser.
Description
(1) technical field
The utility model is a kind of sampling device that detects and analyze, and especially relates to a kind of quick sampling device that high vacuum analysing solid sample and solids surface deposition have the organic contaminant of volatilization or half volatile that is used for.
(2) background technology
The composition of analysing solid sample is to be must be obligato in fields such as environment measuring and scientific researches; but in high-vacuum apparatus; analysis to solid sample; its traditional way is: earlier analyzed solid sample is placed on a fixed position in the high vacuum chamber; then to vacuumizing in the chamber; after sample to be analyzed finishes; must take out solid sample in breakdown high vacuum chamber; during as continuation or the analysis of replacing solid sample; then need to keep on again and again by above-mentioned steps; certainly will take time and effort like this, not only be unfavorable for the protection of high-vacuum apparatus but also the accuracy of impact analysis sample.Especially in environmental pollution detects and analyzes, the organic contaminant with volatilization or half volatile is deposited on solid surface, presses the just sample of express-analysis in time of traditional analytical approach, have a strong impact on the speed of obtaining accurate data.
(3) summary of the invention
The utility model provides a kind of quick sampling device that is used for the high vacuum analysing solid sample or analyzes the solid surface contaminant deposition at the above-mentioned problems in the prior art, its fundamental purpose is: when this device can be placed analysing solid sample flexibly and easily in the high vacuum chamber, do not influence the vacuum tightness in the high vacuum chamber, reach time saving and energy saving, the express-analysis solid sample obtains accurate data.
The utility model is used for the quick sampling device of high vacuum analysing solid sample, comprises a small-sized assisted vacuum chamber and a direct insertion rotatable sample feeding rod of inserting assisted vacuum chamber and high vacuum chamber that is arranged on the high vacuum chamber.Described small-sized assisted vacuum chamber is the vacuum chamber of a low vacuum made from metal tube, the vacuum tightness in its vacuum tightness and high vacuum chamber will differ 3～4 orders of magnitude, it is poor to form a relative vacuum, when sample feeding rod during into and out of the high vacuum chamber, to almost not influence of the vacuum tightness degree in the high vacuum chamber.Described direct insertion rotatable sample feeding rod, comprise by round metal mast certain-length, that surface smoothness is higher, it is bright that the top connects a hand that indicates the circumference scale, its side is placed the graduated scale parallel with sample feeding rod, this sample feeding rod is vertical moving up and down, and left rotation and right rotation can mark the position of analytic sample in the high vacuum chamber exactly.The lower end of sample feeding rod connects an interchangeable nonmetal sample casket, is used to place the analysing solid sample that different shape varies in size.Thereby the time and the accurate data of obtaining analysing solid sample that shorten sample introduction or change sample have been reached.
The quick sampling device of the utility model is simple in structure, flexible to operation, applicable to express-analysis solid sample in any high-vacuum apparatus, especially be useful in laser mass spectrometry instrument, the laser plasma emission spectrum solid sample or be deposited on the analysis of other material on solid sample surface.
