Gas-Phase Molecular Absorption Spectrometer AJ-3700, Automatic Sample Dilution (CAT#: STEM-AL2-0026-ZJF)

The AJ-3700 is a gas-phase molecular absorption spectrometer for water-quality analysis of nitrogen compounds and sulfide. The source lists nitrite nitrogen, ammonia nitrogen, nitrate nitrogen, Kjeldahl nitrogen, total nitrogen, and sulfide among the measurable indicators. The instrument supports automatic dilution when a sample exceeds the configured measurement range. A combined mechanical and electronic pressure-monitoring arrangement is used to monitor operating pressure. Its purge-homogenization system combines a regulated gas source with a constant-flow valve and allows the purge duration and process to be defined. A semiconductor-based online water-removal system uses PWM temperature feedback for moisture control. An internal sintered gas-liquid separation structure is used to improve gas-liquid separation during measurement. The source also states that the system can interface with an automated laboratory workflow.
