AFS-10U Rapid Injection Atomic Fluorescence Spectrometer Introduction: The application fields of AFS-10U intermittent pump rapid injection atomic fluorescence spectrophotometer include food hygiene inspection, environmental sample detection, urban water supply and drainage inspection, agricultural product inspection, geological and metallurgical inspection, cosmetics inspection, textile fiber sample detection, teaching research, clinical medical sample inspection, drug inspection, soil, feed and fertilizer inspection, etc. Features: 1. Fast detection speed and high efficiency Integrated six roller intermittent pump with integral block design, fast detection speed, and high hydrogenation efficiency. Adopting a fast sampling circuit with a sampling frequency of up to 500Hz, reducing inter channel interference and improving detection efficiency. 2. The overall performance is more stable and accurate Drift soft calibration technology is used to improve the stability of Instrumental chemistry. Adopting ARM+FPGA main control architecture, the core components are independently controlled by MCU, and the four cores work together to improve the stability of the circuit system. Electronic flow path control device to improve flow accuracy and stability. 3. Equipped with various intelligent and automation functions Optimize preheating function and reduce detection waiting time. Dual channel automatic illumination, element light timing, and easy to upgrade without adjustment. Large capacity overflow automatic monitoring of waste liquid tank, software intelligent reminder. 4. Friendly software interface and powerful functions It supports user-defined software style, and can quickly view and load recently used methods, sequences and result files through the main menu. Provides guided operations, audit tracking, user permission management, real-time monitoring, automatic wake-up, and preheating program execution after wake-up. 5. Upgradable module Equipped with morphological analysis extension function. Reserved element morphology analysis serial port, which can be upgraded to a morphology analyzer to measure various valence states of elements such as As, Hg, Se, etc. Optional 160 bit or 212 bit automatic sampler for fully automatic analysis.
