Features: 1) The exclusive use of excitation light source drift correction technology, by adding the excitation light source in the same straight line position for the detection of light signal detector, by detecting the excitation light source drift, correction due to light source drift measurement error, a thorough solution to the instrument The problem of long-term stability when measuring. 2) Applying the industry's leading fifth-generation sequential injection-intermittent flow method, we present two advantages of the current atomic peristaltic peristaltic pump injection and injection pump injection, giving full play to their advantages and high reliability (simple structure and low failure rate ), Measurement speed, precision injection, to extend the life of the syringe pump, cleaning time is short and so on. At the same time the exclusive use of peristaltic pump injection and injection pump injection automatic switching function, when the need to automatically configure the standard curve or sample concentration exceeds the standard, the injection pump automatically switches to the standard sample or sample dilution, and then switch to creep Pump sampling continue to measure, greatly improving the life of the syringe pump, reducing user costs. 3) Exclusive with intermittent injection and continuous injection Two injection modes, when the user sample is large and requires accurate measurement, the application of continuous injection mode can play a huge advantage, by increasing the sampling Time to increase the injection volume to eliminate interference in the measurement process to meet the high accuracy of the sample measurement accuracy and stability. 4) The exclusive use of the elimination of inter-channel interference technology, the effective removal of the coupling capacitor storage of the current channel signal, eliminating the impact of the next channel signal to ensure that each data is accurate and reliable. 5) Unique sample blank cleaning monitoring function, which monitors the entire sample measurement, compares the response before sampling and after cleaning, and automatically determines whether the flow path is clean. Reduce the user's difficulty. 6) The exclusive use of a new syringe cleaning device, before each measurement of the outer wall of the syringe to wash, to avoid contamination of the carrier, to ensure the accuracy of low-concentration samples. 7) modular architecture design, modular circuit design using CAN bus and modular mechanical structure design, the instrument is divided into multiple independent modules according to the function to improve the reusability and interchangeability between the instrument modules, saving maintenance Cost, reduce system complexity, with system scalability.
