The utility model discloses an automatic sampler for a spectrophotometer. At present, the commercialization of the spectrophotometer is the cuvette storage solution. Injection solution for solution are manually, the operation is not convenient. Aiming at the defect, the utility model adopts the automatic sample feeding mode, which makes the whole analysis process automatic and improves the work efficiency. The utility model is mainly composed of a newly designed cuvette and a peristaltic pump. The utility model is provided with two inlet ports which are respectively connected with a peristaltic pump 1, and the liquid sampling speed is adjusted by controlling the peristaltic pump 1 to achieve the automatic sampling. The utility model is provided with two liquid discharging ports, one of which is directly connected with a waste liquid bottle, and the other is connected with the waste liquid bottle through the peristaltic pump to discharge the waste liquid. The automatic sampling device of the utility model can realize the automatic sample feeding of the liquid, and can improve the sensitivity of the spectrophotometer.
【技术实现步骤摘要】
本技术专利涉及的分光光度仪是一种提高分析灵敏度并能自动进样的仪器,能广泛地应用在食品、医药、司法、科研与生产上有机、无机物质的定性、定量测定。
技术介绍
目前的商品化的分光光度仪是采用比色皿存放试液。注入试液,换试液等都是人工进行,操作不方便。针对这一缺陷,本技术采用自动进样方式,使得整个分析过程自动化,提高了工效。由于原来的比色皿对试液的利用率不高,光仅通过溶液的极小部分,大部分溶液部分没有用到。本技术采用的比色皿提高了对试液的利用率,对于同体积的试液,提闻了光程,使得测定灵敏度提闻。
技术实现思路
本技术所要解决的技术问题是提供一种能提高分光光度法分析灵敏度,并能自动进样的装置。本技术以如下技术方案解决上述技术问题:本技术设计了一种新的比色皿,其特征在于:整个比色皿横躺放置;比色皿两端开口,一边作为入口,一边作为出口 ;出口侧上下均开口,上面的口直接连接废液瓶,下面的口须通过蠕动泵后连接废液瓶。使得在溶液体积不变的情况下增大液层厚度,从而提高溶液的吸光度以达到增大灵敏度的目的。该比色皿有两个进样口及两个排液口,分别用乳胶管接好。进样及排液的乳胶管分别外接蠕动泵。 ...
