Overview

Suitable for trace analysis and measurement of twelve elements including arsenic, mercury, selenium, tin, lead, bismuth, antimony, tellurium, germanium, cadmium, zinc, gold, etc. in samples. AFS-9700 is an injection injection injection intermittent flow system atomic fluorescence spectrophotometer developed by Beijing Haiguang Instrument Company in October 2008. By using an injection pump to precisely control the injection volume, the absolute injection accuracy of the sample can reach 1%, improving the stability of instrument measurement; The correlation coefficient of the standard curve for single point configuration has been significantly improved compared to peristaltic injection; The accuracy of automatic dilution is high, so the automatic dilution range can reach 200 times. And for the first time, pinch valves were used instead of expensive directional valves. The cost of pinch valves is much lower than that of directional valves, while their lifespan is much longer, greatly reducing the maintenance costs of users' instruments. And the reagent does not directly contact the clamp valve, solving the problem of sample cross contamination caused by the directional valve. The intermittent flow injection system has both the characteristics of accurate injection and fast intermittent flow measurement speed, which can be cleaned online. By changing the data acquisition method on the circuit, the sampling accuracy has been improved, the data curve has become smoother, and the stability of the instrument has been enhanced; Added motherboard security protection measures; Further improve the power supply circuit of the lamp board to enable the instrument to obtain stable and reliable data under unstable power supply from the power grid. This model can use either fully automatic or semi-automatic measurement methods. The application has added features such as selective handling when the concentration exceeds the standard, and automatic cleaning after emergency stop.

2、 Technical features
1. The new injection pump system is the first to incorporate a large peristaltic pump (ten rollers, six channels, each channel can be controlled separately) design into the injection pump system, which combines the advantages of injection and intermittent flow,This absolutely avoids corrosion and leakage of the infusion pump, greatly extending its service life.The sample memory effect is small, cross infection is small, analysis speed is fast, and injection is accurate. More suitable for micro injection and single point automatic configuration standard series.
2Abandoning traditional directional valves, all adopt clamp valves, with a lifespan of hundreds of thousands of times, reagents do not come into contact with the valve, and high reliability.
