ORFIA-608 Flow Injection Analyzer is a multi-channel analyzer with online sample pretreatment functionFully automatic flow injection analyzerThe instrument consists of a multi parameter analysis channel, an automatic sampler, and a software workstation. Each analysis channel has an independent peristaltic pump, chemical analysis template, photodetector, system control, and signal acquisition circuit. The channel is equipped with online heating, online distillation, online UV digestion, and online extraction devices required for this method, and the chemical reaction process is controlled by software. Each channel is independent, and changing the analysis method does not require changing the hardware. The software workstation supports simultaneous detection of up to 8 channels.
Principle of ORFIA-608 Flow Injection Analyzer: Based on the Flow Injection Analysis (FIA) theory, the sample solution is directly injected into the reagent carrier in the form of a "sample plug" in a closed pipeline. The reagent and sample are mixed and reacted in the pipeline, and detection can be carried out without reaction, breaking away from the traditional concept of analysis under steady-state conditions. Chemical analysis can be carried out under non-equilibrium dynamic conditions, greatly improving the analysis speed.
