Atomic Fluorescence Spectrometer

AFS-8750 Atomic Fluorescence Spectrometer

 Product Features:

1) industry-leading dual detector and double channel simultaneous detection function, using multiple detection systems corresponding to excitation light sources, independent testing different elements in the sample, optimized, so that the different elements have different optimum measurement conditions, improve the measurement repeatability and accuracy of the measurement , achieve more accurate when a level of concentration differs considerably.

2) application of industry-leading fifth-generation sequential injection - intermittent flow method for the current atomic fluorescence peristaltic pump injector and injection pump injection in two ways, give full play to their respective advantages, both high reliability (simple structure, low failure rate ), rapid measurement speed, precision injection, extend the service life of the injection pump, cleaning time is short and so on. At the same time the exclusive use of the peristaltic pump injector and injection pump injection automatic switching function, when you need to automatically configure the standard curve or the sample concentrations exceeding encounter, automatically switches to the injection pump injection of standard or sample is diluted again after switching to a peristaltic pump injection method continue to measure, which greatly improves the injection pump life, reduce user costs.

3) Have an exclusive intermittent injection and continuous injection two ways Injection mode automatic switching function, when your sample is large and require precise measurement, the application software continuous injection method can play a huge advantage, by increase the sampling time to increase the sample volume measurement process to eliminate interference to meet the high requirements of accuracy and stability of the samples measured.

4) Exclusive use of eliminating the inter-channel interference, effectively remove the current channel signal which coupling capacitor storage, eliminating the impact on the next channel signals, to ensure that each data is accurate and reliable.

5) Unique sample blank cleaning monitoring function, full control the sample measurement process, compares reactions between before sampling and after cleaning ,,automatically determine whether the flow path clean. Reduce the difficulty of users.

6) Exclusive use of the new syringe cleaning device, cleaning the outer wall of each needle before the measurement, to avoid contamination of carriers to ensure the accuracy of the low concentration of the sample.

7) Modular architecture design, CAN bus modular circuit design and modular mechanical design, classify the instrument according to the functions into a plurality of independent modules ,enhance reusability and instrument interchangeability between modules, save maintenance costs, reduce system complexity, with system scalability.
