Optical Acoustic Gas Analyzer CF4

Product Information

The GASERA ONE CF4 analyzer combines ultra-sensitive cantilever beam enhanced photoacoustic detection technology with a quantum cascade laser source operating at the fundamental mid-infrared spectral absorption line of CF4. This combination offers sufficient sensitivity to reliably detect the smallest CF4 leaks without delay. It also boasts high stability, with calibration cycles ranging from a few months to several years, resulting in a low total cost of ownership.

Technical Specifications

1. Working Principle: Photoacoustic Infrared Spectroscopy

Patented ultra-sensitive optical microphone measurement of the micro-movement of the cantilever light source structure based on MEMS cantilever sensors and laser interferometers: Distributed Feedback Quantum Cascade Laser gas cell stabilized to 50℃ temperature.

2. Standard

Compliant with Low Voltage Directive 2014/35/EU, EMC Directive 2004/108/EC, and RoHS 2 Directive 2011/65/EU.

3. Environmental

Operating Conditions: Temperature Range: 0°C...49°C, Humidity: Non-condensing Pressure Range: 750 mb...1050 mb Dust/Waterproof: IP20 (IEC529)

Storage Conditions: Temperature Range: -20°C to +60°C

Temperature: 0-49° C

Humidity: Non-condensing, with a maximum relative humidity of 80% at 35°C, linearly decreasing to 35% at 49°C.

Pressure: 750...1050 mbar; Gas Flow: Approx. 1 liter/min; Particle Size <1μm

4. Measurement Specifications

Response Time: Varies depending on the User Configurable Integration Time (C.I.T.) and gas exchange program, ranging from approximately 10 seconds to several minutes, depending on the average time and sampling details.

Detection Limit: Below 0.1 ppb

Dynamic Range: Over 5 orders of magnitude (i.e., repeatability: below 1% of the measured values under calibrated concentration operating conditions)

Accuracy: Better than 5% under calibration concentration. Limited by the precision of the calibration gas.

Temperature Stability: Environmental temperature variations within the operating temperature range will not cause drift.

Pressure Stability: Pressure fluctuations within the range of the sample gas will not cause drift.
