Description
Technical field
The utility model relates to the liquid-way system field of atomic fluorescence spectrometer, especially relates to the liquid-way system field for the sequential injection atomic fluorescence spectrometer.
Background technology
The sampling system of atomic fluorescence is divided into Generation-Atomic Fluorescence Spectrometry, continuous flow and three kinds of input modes of sequential injection.Generation-Atomic Fluorescence Spectrometry sampling system and continuous streaming sample introduction system generally adopt the peristaltic pump sample introduction, and flow path system is simple, cost is low, but automaticity is low, sampling precision and repeatability relatively poor.The former reagent consumption is larger, causes analysis cost higher; Latter's reagent and sample consumption are all larger, and memory effect easily occurs.The sequential injection sample introduction generally adopts high precision syringe pump and multi-position valve sample introduction, and flow path system is complicated, cost is relatively high, but automaticity is high and have splendid sampling precision and repeatability, and reagent and sample consumption are all smaller.The sequential injection sampling system has been widely used in high-end atomic fluorescence spectrometer at present.
The core component of sequential injection sampling system mainly contains syringe pump, multi-position valve and accessing ring etc., wherein the effect of syringe pump is to realize sampling with high precision and injected sample, the effect of multi-position valve is the switching that realizes flow path system in the sequential injection sampling process, and the effect of accessing ring is sample solution and the current-carrying that the store injection pump quantitatively sucks.Sample solution is in the process that is inhaled into or releases accessing ring, and meeting and current-carrying solution interpenetrate the generation diffusional effect.Can cause the serious broadening in analytic signal peak when diffusional effect is serious, and have memory effect to a certain degree, impact analysis sensitivity and repeatability.Above-mentioned diffusional effect can't be avoided fully, but how effectively to control diffusional effect, realize that sample solution reappears at the height of the process that is inhaled into or releases accessing ring, obtain better sensitivity for analysis and repeatability, except being subjected to more to depend on the design of accessing ring syringe pump capture velocity and injection speed affect.
In the sequential injection sampling system of atomic fluorescence, be stored sample solution and current-carrying solution, effectively eliminate simultaneously memory effect, accessing ring generally has the length of 2～6 meters.For the commercialization atomic fluorescence of paying close attention to image product and outward appearance, at first pipeline how to process length like this becomes needs the problem that solves.But, regrettably at present the sequential injection atomic fluorescence normally with the pipeline of accessing ring disorderly and unsystematic domain on the single line axle or arbitrarily be coiled into ring-type, use band tighten rear-mounted on flow channel switching valve, had a strong impact on the image product of sequential injection atomic fluorescence.More seriously, when sample solution is injected the pump suction or releases in the irregular pipeline of this stream, can have a strong impact on the stability of sample solution transmission, can bring serious memory effect and diffusional effect simultaneously, have influence on the stability and repeatability analyzed.
