Innova 1314

Photoacoustic Multi-gas Monitor - Innova 1314

LumaSense offers the maket quality photoacoustic-based gas monitoring solutions. The Photoacoustic Multi-gas Monitor 1314 is a highly accurate, reliable and stable quantitative gas monitor. Its measurement principle is based on the photoacoustic infra-red detection method. This means that the 1314 can measure almost any gas which absorbs infra-red light.

Selectivity is achieved through the use of optical filters. By installing up to 5 optical filters in the 1314, it can measure the concentration of up to 5 component gases and water vapor in any air sample. Detection limit is gas-dependent, but is typically in the ppb region. The accuracy of measurements is ensured by the 1314's ability to compensate for temperature and pressure fluctuations, water-vapor interference and interference from other gases known to be present (Cross-compensation). Reliability of measurement results is ensured by regular, automatic self-tests.

The measurement system requires no consumables and very little regular maintenance and is therefore ideally suited for permanent monitoring tasks

Uses

• Emission monitoring - of exhausts from chemical processes, Ammonia in stacks, scrubber efficiency and filter break-through
• Process quality control measurements - of trace impurities in pure gas production or SF6 leaks from operational transformers
• Occupational health and safety measurements - of possible production or accumulation of toxic/carcinogenic substances in working areas
• Automotive monitoring - of alcohol content in vehicle exhausts and production of Ammonia and N2O in diesel exhausts

Features

• Selectively measures a wide range of gases/vapors
• Linear response over a wide dynamic range
• High stability (low drift) makes calibration only necessary 1-2 times a year
• Extremely reliable due to self-testing procedures
• User-friendly procedures for calibrating the monitor, presenting and analyzing measurement data via the PC user-interface
• Accurate - compensates for temperature fluctuations, water-vapor interference and interference from other known gases
• Extremely low-volume flushing possible
• Fits in a standard 19 inch rack and collects samples from points up to 50m away
• Presents measurement data both in tabular and graphic formats - up to 5 gas concentrations and water vapor graphs displayed, simultaneously

Innova Gas Detection Limits

The optical filters used in the instruments display different characteristics while sharing a basic design. Each filter comprises three separate infra-red elements; a narrow-band pass element, a short-wave pass element and a wide-band pass element. The narrow-band pass element has very specific transmission characteristics defined by the short-wave pass and wide-band pass elements, which prevents transmission of light at other wavelengths.
