Problems solved by technology

[0005] The current atomic fluorescence spectrometers only have a certain sampling method, but cannot take into account multiple sampling methods, and cannot meet the various needs of users. If you buy multiple atomic fluorescence spectrometers with different sampling systems, the operating cost will increase. and other additional costs, so it is necessary to find a technical means that can combine the advantages of both

Abstract

The invention discloses a multifunctional joint sampling system for an atomic fluorescence spectrometer. The system comprises a peristaltic pump interruption sampling device, an injection pump sampling device, a shifter, a four-way hybrid reaction module, a solution storage device and a control system. According to the system, multiple sampling modes can be switched via the control system, multiple sampling modes can be considered simultaneously to a certain degree, and multiple sampling modes are integrated on one device simultaneously. Under the peristaltic pump interruption sampling mode, the injection pump part and three-way valve parts stop working, and peristaltic pump parts simultaneously absorb samples (or carrier liquid) and a reducing agent; under the injection pump sampling working mode, the injection pump part and the three-way valve parts are responsible for absorbing samples (or carrier liquid), and the peristaltic pump parts help to absorb the reducing agent, so that the cost is effectively lowered, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the field of precision instruments and meters, in particular to a multifunctional combined sampling system for an atomic fluorescence spectrometer. [0002] Background technique [0003] The atomic fluorescence spectrometer is a commonly used spectral analysis instrument in the laboratory. The sampling system is an important part of the atomic fluorescence spectrometer. Its sampling accuracy, sensitivity, service life, and stability are important indicators that affect the testing effect of the atomic fluorescence spectrometer and the use of the instrument. [0004] According to the injection method of atomic fluorescence spectrometer, it can be divided into flow injection, peristaltic pump intermittent flow and syringe pump sequential injection, etc., each method has its own advantages and disadvantages. Among them, the peristaltic pump intermittent flow technology has a long history and is mature and stable. The outstanding ...
