Please fill out the application questionnaire and contact us to discuss the application and configurations. Introduction Cleanrooms must be controlled for contamination levels. Accurate, reliable and low maintenance control of cleanroom airborne contamination enables significant yield improvements. High sensitivity of the GASERA ONE CF4 enables fast response time for detecting contamination of the production environment. Furthermore, the direct absorption measurement provides extremely good long-term stability due to its zero-background nature. The GASERA ONE CF4 can be integrated into a cabinet along with other instrumentation such as particle monitors. GASERA ONE CF4 analyzer is based on combining ultra sensitive cantilever enhanced photoacoustic detection technology with Quantum Cascade Laser source operating at a Mid-IR fundamental spectral absorption line of CF4. This combination provides enough sensitivity to reliably detect the smallest spills of CF4 without any delay. It also gives an exceptionally high level of stability with a re-calibration period ranging from several months up to several years, and thus it offers a low total cost of ownership. Features Accurate, reliable and low maintenance control of cleanroom contamination selective trace level monitoring of CF4 Highly selective against aldehydes and other VOCs Below 0.1 ppb limit detection Response time user configurable from 10 seconds to few minutes Wide dynamic range and stable operation Requires no consumables Low sample volume (few ml) Recommended re-calibration interval of 12 months User configurable monitoring tasks Intuitive user interface Built-in display presents results both numerically and graphically Remote operation via local network Measurement Performance Detection Limit: < 0.1ppb Response Time: dependent on user configurable channel integration time (C.I.T.) and gas exchange routine. From approx. 10 seconds to few minutes depending on averaging time and sampling details. Dynamic Range: over 5 orders of magnitude (i.e. 100 000 times the detection limit) Repeatability: < 1% of measured value in operational conditions at the calibration concentration. Accuracy: Better than 5% at the calibration concentration. Limited by the calibration gas accuracy Stability: No drift due to ambient temperature or pressure variations within recommended working conditions System Specifications Form Factor: 19” 3U rack-mount / tabletop unit Dimensions: 48.4 × 13.9 × 44 cm (19.1 × 5.5 × 17.3 in) Weight: ~13 kg Display: Built-in computer with 7” WSVGA screen Internal Gas Volume: 30 ml Data Storage: ≥ 1 year continuous monitoring Operating Conditions Temperature: 0°C to +49°C Humidity: Non-condensing Pressure: 750–1050 mbar Dust/water resistance: IP20 (IEC 529) Sample Gas Conditions: Temperature: 0°C to +49°C Humidity: Up to 99% RH (non-condensing, temperature dependent) Flow Rate: ~1 L/min Particle Size: < 1 µm Electrical & Interfaces Input Voltage: 90–264 VAC, 47–63 Hz Power Consumption: Max. 75 W Interfaces: Ethernet, USB, optional Serial Protocols: MODBUS, AK protocol Outputs: Current or voltage signal Compliance & Standards Low Voltage Directive 2014/35/EU EMC Directive 2004/108/EC RoHS 2 Directive 2011/65/EU Applications Airborne molecular contamination (AMC) in semiconductor cleanrooms Related publications: Sensitive and fast gas sensor for wide variety of applications based on novel differential infrared photoacoustic principle (2012) – Results from MINIGAS and GHG Flux -projects Applied Spectroscopy Reviews (2007): Photoacoustic Gas Analysis Using Interferometric Cantilever Microphone If you are interested in other gas types or multi-gas analyzers, please contact us about your application: • Formaldehyde • Greenhouse gases • HF, HCl, HCN, SO2, NO2, EtO • SF6, NOVEC • CF4, PFCs • Benzene • Many more!
