LT-N type online trace nitrogen analyzer in argon Introduction: LT-N online argon trace nitrogen analyzer is an online analyzer based on enhanced plasma discharge (EPD) technology, a classic application of spectral compensation technology. Compared to other products on the market with single wavelength detection, the online argon trace nitrogen gas analyzer uses a combination of our stabilization/focusing electrode and electron injection electrode with differential optical detection, while improving performance and signal stability . Combines focusing/stabilizing and electron injection electrodes and spectral compensation techniques. These techniques address the issues of baseline fluctuations due to flow and pressure changes, as well as the effects of quenching molecules such as H2O, on the measurement, thereby greatly reducing drift and noise. Application areas: air separation plants, chemical plants, argon purification plants, helium liquefaction plants, special gas laboratories, steel plants, leak detection, welding control, process control, gas management systems, glove boxes, trace nitrogen in semiconductor manufacturing analysis and detection. Features: 1. Detection limit < 0.5ppb (enhanced type), <2ppb (standard type) 2. Zero interference: spectral difference technology 3. Patented design, United states of america patent number: 012720-0156ACTIVE, zero leakage flow controller 4. Industrial touch screen display 5. 12-month internal data storage IoT access 6. Ultra-compact 19-inch rack design Technical parameter: Detection limit: < 0.5 ppb Range: 0-1 ppm 0-10 ppm 0-100 ppm up to 1% Drift: < 0.5% F.S. Response time: < 10 sec. for 90% step change @ 75 mL/min Standard Features: 3 x Range Relays 1 x Status Relays 2 x Alarm Relays; Ethernet/IIoT Access - Remote Control - Embedded I/O Ports; MQTT Protocol for M2M Communication and RS-232; Standard 4-20 mA output; Interface: Industrial Grade Touch Screen - Electronic Flow Control Overview of data trends and alarm history - internal data storage for December Gas Connection: 1/8” LipLOKTM (with any industrial/instrument grade fittings) Calibration Gas High Point Calibration Low Point Calibration: > 90% of span N2 in Ar or He 0-20% of span N2 in Ar or He Sample flow rate: 5 mL/min to 200 mL/min Inlet Pressure Range: 3 to 25 PSIG (other pressures available on request) Operating temperature: 5°C to 40°C Operating Voltage: 24 VDC Power consumption: 40 watts Weight: 10 lbs Dimensions: 133 x 202 x 330 mm (5.25 x 8.0 x 13.0 in) (19" rack design)
