Abstract
The utility model relates to a new device, particularly a vertical gatherer for sample solution, which is completely different from the solution guiding system of Scott type popularized at home and abroad. The utility model not only keeps the advantages of the popular device but also has the advantages of low memory effect, rapid signal ascending and descending speed, high line back ratio, simple structure and easy cleaning. When used in a plasma emission spectrum analyzer and a plasma mass spectrometer, the utility model has good effect. The analyzing time is shortened by more than one time and the argon consumption is decreased by more than one time.
Description
The utility model relates to a kind of sample solution import system device, belongs to field of analytic instrument.Be mainly used in plasma emission spectroscopy (ICP-AES) and plasma mass (ICP-MS).
The late nineteen eighties, ICP-AES and ICP-MS are developed rapidly as a kind of advanced person's analytical instrument.Plasma emission spectroscopy method and plasma mass method are to utilize the emission spectrum of atom, ion or content and the composition that mass spectrum comes working sample, and mass spectroscopy can also be carried out structure analysis and isotope analysis.The speciality of these two kinds of analytic approachs is can carry out multielement to analyze simultaneously, and is highly sensitive, the precision height, and it is low to detect lower limit, the resolving power height, the range of linearity is wide, can carry out qualitative analysis, also can carry out accurate quantitative test.Be a kind of than the more superior instrumental method of atomic absorption analysis (AAS).
At present, the popular solution import system of commercial apparatus adopts scott type (double-deck garden cartridge type) mostly both at home and abroad, as shown in Figure 2.This system signal rise and fall are slow, and memory effect big (returning zero-time length) therefore, not only makes lengthening analysis time, and the argon gas consumption is also big.This is disadvantageous to proximate analysis.
The utility model structure as shown in Figure 1.Spray chamber 1 is a vertical hollow cone (making also available other resistant material usually with hard glass), and sprayer 5 the place aheads are 180 ° of angles mutually with a collision ball 4, and the little elevation angle that makes progress is arranged.
Principle of work and process: high-speed gas is after the ejection of sprayer mouth, sample solution is vaporific ejection through kapillary from spout, by the further refinement of frontal collisions ball, according to principle of hydrodynamics, the central shaft flow velocity greater than around flow velocity, the result, big or small droplet is separated automatically in transport process: little droplet imports torch pipe (Torch) by carrier gas, inwall around big droplet is diffused into is condensed into the waste liquid mouth 6 that drop flows to bottom 2 rapidly at last and drains.
This device is through experimental study and carry out detailed comparative study with Scott type device and show, not only sensitivity, detect lower limit, precision, the range of linearity etc. and keep previous levels (many elements even surpass), and line is carried on the back than height, signal rise and fall speed is fast, memory effect is very little, return zero-time above, sample room scavenging period shortening fast again, the whole sample analysis times of result add fast again more than, argon gas consumption reduces more than one times.Apparatus structure is simple, cleans easily.Above-mentioned speciality is brought great convenience to proximate analysis.
This device also is applicable to that other requires the little solution import system of memory effect.
The utility model structure accompanying drawing 1 explanation: 1, vertical spray chamber; 2, base; 3, O-ring seal; 4, collision ball; 5, sprayer; 6, waste liquid eductor; 7, torch pipe (Torch).
Claims (1)
1, a kind of novel vertical solution import system device, its feature comprises vertical spray chamber 1, sprayer 5 and collision ball 4.Spray chamber is a vertical type, can be that cone, ball awl complex or other curve revolve front cover, makes of hard glass or other resistant material, and base 2 usefulness teflons or other resistant material are made, and collision ball 4 requires can add and can not add according to actual analysis.Sprayer 5 is 180 ° mutually with the collision ball.And have one to vertical angle.
