Description
技术领域 technical field

背景技术 Background technique
现有技术中，光谱类分析仪器被广泛应用于元素的定量测定。原子荧光光度计是一种常见的光谱类分析仪器。原子荧光光度计测试过程的基本工作原理是：测试样品的各元素经反应形成相应的氢化物，与氢气和载气混合，进入原子化器实现原子化后，在激发光源的照射下发出特定波长原子荧光信号，检测器接收此荧光信号并根据此荧光信号强度与元素浓度成正比的特性来获得元素的浓度数据。 In the prior art, spectral analysis instruments are widely used in the quantitative determination of elements. Atomic fluorescence photometer is a common spectroscopic analysis instrument. The basic working principle of the atomic fluorescence photometer test process is: each element of the test sample reacts to form a corresponding hydride, mixes with hydrogen and carrier gas, enters the atomizer to achieve atomization, and emits a specific wavelength under the irradiation of the excitation light source The atomic fluorescence signal, the detector receives the fluorescence signal and obtains the concentration data of the element according to the characteristic that the intensity of the fluorescence signal is proportional to the concentration of the element.
目前，大部分原子荧光光度计具有自动稀释、自动进样功能。传统的自动进样运行方式是自动进样器的采样针移动到样品位吸取待测样品，然后采样针移动到载流位吸取载流推动样品进入反应器。采样针吸取样品后直接吸取载流，可能造成载流的污染，影响实验结果的准确性，测试精度较低。 At present, most atomic fluorescence spectrometers have automatic dilution and automatic sample injection functions. The traditional automatic sampling operation mode is that the sampling needle of the automatic sampler moves to the sample position to absorb the sample to be tested, and then the sampling needle moves to the current carrying position to absorb the carrying current and push the sample into the reactor. The sampling needle draws the carrier current directly after sucking the sample, which may cause the pollution of the carrier current, affect the accuracy of the experimental results, and the test accuracy is low.
