Abstract
The utility model provides an atomic fluorescence flame observation window for atomizer export flame burns in observing the atomized chamber, and window frame is observed to fixed being provided with on the atomized chamber wall body observe window frame be close to the inboard slope of atomized chamber be provided with before optical filtering glass observe window frame and be close to the vertical glass that filters behind the at least one deck that sets up in the atomized chamber outside. The utility model has the beneficial effect of simple structure, the stray light reflex of leaking the outside is into effectively gone out, and very big limit ground has reduced interior outside fluorescence and has got into the influence that optical system led to the fact to the signal acquisition of receiver, and the whole that has improved the instrument detects the precision.
Description
Technical field
The utility model belongs to testing tool technical field, especially relates to a kind of atomic fluorescence flame view window.
Background technology
Atomic fluorescence spectrophotometer is a kind of chemical analysis instrument for measuring element trace level content in sample.Its principle of work utilizes chemical method to make tested element generation chemical reaction generate hydride, by atomizer outlet through lighting formation flame, light source activation is utilized to contain the flame of tested element, tested element produces atomic fluorescence after obtaining energy jump, by measuring the intensity of atomic fluorescence, calculate tested constituent content by analysis.Generally need in instrument work to observe flame situation at any time, to ensure carrying out smoothly of detection.In prior art, be generally just to perforate on the atomized chamber wall body of atomizer outlet flame position, filter glass is set, then observe flame combustion situation through glass.The disadvantage of this watch window is: 1. external stray light easily enters atomized chamber by watch window, is received by the receiver, thus affects the correctness of testing result; 2. the excitation source of boring cathode modulation also can enter receiver by the glass-reflected of view window or via other diffuse reflections, and then affects testing result, causes prohibited data detection true.
Utility model content
The purpose of this utility model is for solving the deficiencies in the prior art, a kind of atomic fluorescence flame view window is provided, structure is simple, effectively the parasitic light that outer side leakage is entered is reflected away, reduce interior outside fluorescence to the utmost and enter the impact that the signals collecting of optical system on receiver cause, improve the whole detection precision of instrument.
The technical solution of the utility model is: a kind of atomic fluorescence flame view window, for observing atomizer outlet flame burning in atomized chamber, atomized chamber wall body is fixedly installed view window framework, filter glass before described view window framework is tiltedly installed with inside atomized chamber, arranges at least filter glass after one deck at described view window framework near atomized chamber outside upright.
Further, described front filter glass and horizontal plane angle are 20 degree-80 and spend.
Further, described front filter glass and horizontal plane angle are 45 degree.
Further, described atomized chamber wall body installs optical system, described optical system is arranged in the horizontal direction just to atomizer outlet flame position.
Further, also comprise receiver, described receiver is arranged in the horizontal direction just to the outside of optical system.
Further, described view window framework is arranged in the horizontal direction just to atomizer outlet flame position.
Further, at described view window framework filter glass after atomized chamber outside upright arranges three layers.
The advantage that the utility model has and good effect are: the utility model is by Orientation observation window frame on atomized chamber wall body, by filter glass before on view window framework, inner side exciting light is reflected into vertical direction, avoid entering optical system, affect receiver to receive, rear filter glass on view window framework, effectively prevent external stray light to enter atomized chamber, affect the receiver after optical system and receive atomic fluorescence.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Shown in structural representation as of the present utility model in Fig. 1, the utility model provides a kind of atomic fluorescence flame view window, for observing atomizer 2 outlet flame burning in atomized chamber 1, atomized chamber 1 wall body is fixedly installed view window framework 3, filter glass 4 before described view window framework 3 is tiltedly installed with inside atomized chamber 1, arranges at least filter glass 5 after one deck at described view window framework 3 near atomized chamber 1 outside upright.Described front filter glass 4 is 20 degree-80 with horizontal plane angle and spends.Described front filter glass 4 is 45 degree with horizontal plane angle.
Described atomized chamber 1 wall body installs optical system 6, and described optical system 6 is arranged in the horizontal direction just to atomizer 2 outlet flame position.Also comprise receiver 7, described receiver 7 is arranged in the horizontal direction just to the outside of optical system 6.
Described view window framework 3 is arranged in the horizontal direction just to atomizer 2 outlet flame position.At described view window framework 3 filter glass 5 after atomized chamber 1 outside upright arranges three layers.
The course of work of this example: the utility model provides a kind of atomic fluorescence flame view window, atomized chamber 1 wall body is fixed a view window framework 3, filter glass 4 before view window framework 3 is tiltedly installed with inside atomized chamber 1, exciting light and parasitic light inside atomized chamber 1 are upwards reflected, avoid entering optical system 6, affect receiver 7 to receive, when current filter glass 4 is 45 with horizontal plane angle, by exciting light through the light reflection of flame to vertical direction, effectively prevent its after diffuse reflection transmitted light system 6 on the impact of receiver 7.Simultaneously slanted angle is that the parasitic light that outer side leakage is entered also reflects away by the front filter glass 4 of 45 degree, reduce further the impact on receiver 7; At described view window framework 3, at least filter glass 5 after one deck is set near atomized chamber 1 outside upright, what effectively filter out extraneous parasitic light enters atomized chamber 1, thus the impact reduced accuracy of detection, when at view window framework 3 after atomized chamber 1 outside upright arranges three layers during filter glass 5, can be reduced to and level off to 0 by parasitic light, Detection results is more accurate; The utility model provides a kind of atomic fluorescence flame view window, reduces interior outside fluorescence to the utmost and enters the impact that the signals collecting of optical system 6 on receiver 7 cause, improve the whole detection precision of instrument.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
