Abstract
The utility model relates to a hydride generation-atomic fluorescence spectrometry instrument with a double-channel multi-lampholder system, which comprises an atomizer and a photomultiplier tube positioned on one side of the atomizer, wherein the left side or the right side of the photomultiplier tube is provided with a double-channel multi-lampholder system surrounding the atomizer 4; both sides of the photomultiplier tube are respectively provided with a one-channel multi-lampholder system surrounding the atomizer, lenses are arranged among each multi-lampholder system, the photomultiplier tube and the atomizer 4, lampholders of each multi-lampholder system can have same number and can also have different number. The utility model has the advantage of high convenience and work efficiency.
Description
Technical field
The utility model relates to a kind of hydride generation-atomic fluorescence spectrometer, specifically, relates to the hydride generation-atomic fluorescence spectrometer with many lamp brackets of two pass system.
Background technology
Hydride generation-no chromatic dispersion two pass atomic fluorescence spectrophotometer has been widely used in industries such as environmental protection, potable water, sewage detection, food hygiene detection, health and epidemic prevention, medicine, pottery, metallurgy, geology at present, be mainly used to detect some form easily hydride to human body poisonous and harmful or beneficial trace elements, as As, Sb, Bi, Hg, Se, Te, Ge, Sn, Pb, Zn, Cd etc.In these elements, elements such as As and Sb, Bi and Hg, Se and Te, As and Hg, As and Se can be surveyed together by two pass, and Ge, Sn, Pb, Zn, Cd can only measure by single track because reaction conditions has nothing in common with each other.Existing in the market hydride generation-no chromatic dispersion two pass atomic fluorescence spectrophotometer all is a two pass list lamp bracket system, and promptly per pass can only be adorned a lamp.When element is measured in conversion, just need do shutdown like this, change lamp, start, light modulation, preheating, reset a series of not only time-consuming but also loaded down with trivial details work such as condition, reduce work efficiency.
Adopt many lamp brackets system in medium-to-high grade Atomic Absorption Spectrometer, its fundamental purpose is to need only manually or automatically to rotate the replaceable element lamp of lamp bracket when element is measured in conversion, and need not do above-mentioned a series of both time-consuming loaded down with trivial details work.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of hydride with many lamp brackets of two pass system that one atomic fluorescence spectrometer takes place.
Hydride generation-the atomic fluorescence spectrometer of many lamp brackets of two pass described in the utility model system, comprise atomizer, be positioned at the photomultiplier of atomizer one side, in the left side of photomultiplier or the right side be provided with many lamp brackets of two pass system around atomizer, perhaps both sides are respectively arranged with the many lamp brackets system together around atomizer, be provided with lens between each many lamp brackets system and photomultiplier and atomizer, the quantity of each road many lamp brackets system lamp bracket is identical or inequality.
Described many lamp brackets system is the lamp bracket with 2-6 lamp.
Hydride generation-atomic fluorescence spectrometer with many lamp brackets of two pass system described in the utility model has greatly improved convenience and work efficiency that instrument uses.
Description of drawings
Fig. 1 is the synoptic diagram with hydride generation-atomic fluorescence spectrometer of many lamp brackets of two pass system described in the utility model;
Fig. 2 is many lamp brackets system schematic shown in Figure 1.
Embodiment
Referring to Fig. 1, hydride generation-atomic fluorescence spectrometer with many lamp brackets of two pass system described in the utility model, comprise atomizer 4, be positioned at the photomultiplier 3 of atomizer one side, in the left side of photomultiplier 3 or the right side be provided with many lamp brackets of two pass system 1 around atomizer 4, perhaps both sides are respectively arranged with the many lamp brackets system 1 and 2 together around atomizer 4, are provided with lens 5,6,7 between each many lamp brackets system and photomultiplier 3 and atomizer 4.
The quantity of each road many lamp brackets system lamp bracket can be the same or different.Described many lamp brackets system 1,2 can be the lamp bracket of the lamp bracket of the lamp bracket of the lamp bracket with two lamps, 3 lamps, 4 lamps, 5 lamps or the lamp bracket of 6 lamps.Shown in Figure 2 is the lamp bracket system schematic of 4 lamps, and A is a conversion equipment, and 8,9,10,11 is element lamp.During use, as required,, select the element lamp that to survey by the position of conversion equipment rotation lamp.
With two pass three lamp brackets is example, when placing As, Bi, Te element lamp on many lamp brackets together, on the many lamp brackets in another road, place Sb, Hg, Se element lamp, then by rotating lamp bracket (manual or automatic), the two pass that just can realize above-mentioned As and Sb, Bi and Hg, Se and Te, As and elements such as Hg, As and Se easily is with surveying, and two element lamps that will measure under just can preheating in present two elements are containeds have shortened the shared time of element lamp preheating greatly.Many lamp brackets system is because lamp bracket is more in addition, and normal some element lamps of surveying substantially just are fixed on the lamp bracket and modulated good light path at ordinary times, does not just need light modulation again when therefore measuring next time.And existing two pass list lamp bracket device after measuring two elements, needs to do four shutdown at least when surveying above-mentioned other element again, changes lamp, start, light modulation, preheating, resets a series of not only time-consuming but also loaded down with trivial details work such as condition.
Claims (2)
