The ammonia escape equipment at Zhoukou Lactic Acid Field, managed by Shandong Xinze Instrument Co., Ltd., has officially started operation.

Since its commissioning, the ammonia escape equipment project at Zhoukou Lactic Acid Field has operated smoothly, and after treatment, the indicators have reached the design standards, meeting national environmental protection requirements and winning praise from the staff! The sampling method of this device is in-situ high-temperature tracing extraction. The basic principle of this device is based on ultraviolet differential absorption spectroscopy (DOAS) technology and tunable semiconductor laser absorption spectroscopy (TDLAS) technology; The principle of ultraviolet differential absorption spectroscopy technology is that the same gas has different absorptions in different spectral bands, and the absorption superposition effect of different gases in the same spectral band. Through algorithmic analysis of continuous spectra, multiple gases can be measured simultaneously, effectively avoiding interference between each component; Laser spectroscopic gas analysis technology has been widely applied in various gas monitoring fields that require high sensitivity, response time, and interference free background gases.
