Water quality total organic carbon monitor

Abstract

This utility model relates to the field of online water quality monitoring technology, and provides a total organic carbon (TOC) monitor, including a sample injection component, a syringe pump, an aeration component, a combustion furnace, a flow control component, a flow path filter component, a multi-channel NDIR detector, and a host computer. The sample injection component and the aeration component are both connected to the syringe pump. The sample injection component is connected to the combustion furnace via a sample injection tube. The flow control component is connected to the aeration component and the combustion furnace. The combustion furnace is sequentially connected to the flow path filter component and the multi-channel NDIR detector. The multi-channel NDIR detector is connected to the host computer. The multi-channel NDIR detector used in this utility model is equipped with filters of different wavelengths and dual infrared detectors, capable of detecting CO2 concentrations of 2000 ppm and 500 ppm, enabling the measurement of high-concentration CO2. Furthermore, by adjusting the syringe pump and the flow control component to increase the flow rate, the measurement of low-concentration CO2 can be achieved. This utility model can meet the TOC measurement needs of various scenarios.
