]]> Monitor Formaldehyde levels in realtime with high sensitivity and accuracy using the MIRA Ultra VOC gas analyzer.
Introducing the MIRA Ultra VOC, the World’s first portable high accuracy formaldehyde gas analyzer.
The Ultra VOC is based on Aeris’ revolutionary, miniature laser-based sensor engine, which achieves sub-ppb sensitivity and accuracy in seconds.

The Ultra Series analyzer provides extended, low drift performance via its precision temperature stabilized optical core.

Portable Ultra systems can be uniquely employed for a wide range of fixed, handheld, and mobile applications. The low power consumption of Ultra systems makes them ideal for solar powered applications.
Aeris MIRA Series analyzers operate in the middle infrared (MIR) region, achieving unparalleled specificity and sensitivity in a compact, low power consumption platform. The ability to monitor HCHO in real-time with a portable analyzer enables a wide range of lab as well as field applications that were previously impractical due to traditional size, weight, power, and cost constraints. Ultra Series analyzers offer performance levels traditionally associated with much larger, more expensive gas analyzers, representing a paradigm shift in high accuracy laser-based gas analysis systems.

Key Features:

  • Temperature and pressure stabilized core
  • Autonomous, built-in calibration or zero cycle
  • 1 or 2Hz operation
  • GPS ready for creating HCHO “maps”
  • Built-in wifi, RS-232, and optional analog out
  • Lowest, 20W (average) power consumption
  • Maintenance-free sensor, user-serviceable filters
  • 2-port, differential sampling, built-in pump.

Real-Time Ambient and Source Monitoring

The MIRA Ultra VOC is suitable for long-term ambient monitoring applications as well as emissions quantifications studies. Common sources of formaldehyde
include including engineered wood products, glues and paints, and industrial facilities such as die-cast or plastics manufacturing plants. Comparisons with ASTM methods quantify system accuracy and linearity from ppb to ppm levels, determining absolute HCHO levels in minutes instead of hours, while eliminating wet chemistry steps and consumables (column) associated with other methods.

As an absorption-based method, MIRA Ultra systems achieve high sensitivity and linearity over an extremely wide concentration range. Ultra VOC systems come equipped with two programmable sample ports and associated software that enables autonomous calibration (or rezeroing) as well as differential measurements. As the optical core in the Ultra VOC is heated to 40°C, it is ideal for use in humid environments where the potential for condensation in the analyzer is of concern.

Operating principle

GasEye Extractive is a laser spectrometer that uses single line molecular absorption spectroscopy. A semiconductor laser emits a beam of infrared light which passes through the process and impinges the detector on the receiver side. When the target gas is present the light intensity changes and this can be used to determine the concentration of the measured specimen. The wavelength of the radiation emitted by the laser is chosen to match the specific absorption line wavelength of the gas. The laser continuously scans this single absorption line with a very high spectral resolution. The measurement is free of cross-interferences since the laser light is absorbed very selectively by only one specific line in the scanned spectral range.

]]> GasEye Cross Duct MG (Multi Gas) is a high performance in-situ analyzer that provides analysis for 17 standard gas combinations and can be customised for specific combinations. GasEye Cross Duct MG utilizes tunable diode laser (TDL) absorption spectroscopy. The central unit sends a laser light through the process which is detected by the receiver unit mounted on the opposite side of the process. When a gas of interest is present in this process, it will absorb the laser light. The optical power detected in the receiver unit will depend on the concentration of the gas, temperature, pressure, and optical pathlength according to Lambert’s Beer law. Thus in order to determine the gas concentration, the analyzer requires information regarding temperature, pressure, and optical pathlength. Temperature and pressure signals can be provided by analog inputs, via industrial communication protocols, or as manual values via Webserver or HMI.

In the GasEye Cross Duct analyzer, the laser wavelength is specifically chosen to match the fingerprint region of the particular gas of interest and is being continuously scanned over the absorption line(s). Since full spectral information is recovered with very high spectral resolution the analyzer remains immune to foreign gas broadening and is immune to cross-interferences from dust and any other gas constituents in the process. GasEye Cross Duct by design can operate in several wavelength regions from Near-Infrared to Mid-Infrared.

Operating principle

GasEye Extractive is a laser spectrometer that uses single line molecular absorption spectroscopy. A semiconductor laser emits a beam of infrared light which passes through the process and impinges the detector on the receiver side. When the target gas is present the light intensity changes and this can be used to determine the concentration of the measured specimen. The wavelength of the radiation emitted by the laser is chosen to match the specific absorption line wavelength of the gas. The laser continuously scans this single absorption line with a very high spectral resolution. The measurement is free of cross-interferences since the laser light is absorbed very selectively by only one specific line in the scanned spectral range.

INFLUENCES ON THE MEASUREMENT
Temperature

The influence of temperature on the measured absorption line is compensated by internal algorithms. The process gas temperature must be provided as a signal into the instrument. The temperature measurement is used to apply a correction of the temperature on the observed line strength. Temperature compensation is obligatory and without it the concentration output is erroneous.

Pressure

The influence of pressure on the measured absorption line is compensated by internal algorithms. The process gas pressure must be provided as a signal into the instrument. For known pressure values, the GasEye Cross Duct spectrometer adapts the line shape. Additionally, an external pressure signal can be fed to the analyzer to provide complete mathematical compensation of the pressure influence including the density effect (depending on a specific application and target gas).

Interferences

The GasEye Cross Duct can measure the desired gas components very selectively. It may happen that the absorption line of the measured gas is influenced by the presence of other gases. This influence is compensated by the full shape of the detected signal curve analysis and applying algorithms that correct the discrepancies accordingly.

MG (Multi Gauge)
The GasEye Cross Duct MG (Multi Gauge) analyzer consists of a pair of cross-duct sensors – a transmitter and a receiver unit as well as a central unit. The transmitter unit emits laser radiation directly through the process containing the constituents of interest. The receiver unit collects the radiation on the other side of the process duct. The central unit, located close to the transmitter unit (< 2 meters) contains analyzer electronics, MMI and I/O. The receiver unit is connected to the central unit by means of a hybrid loop cable (included) and the transmitter unit is connected to the central unit by one or two electrical cables (included).
