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).

]]> Portable stack gas and emission analyzer

For stack testing and emissions monitoring, time is the most important resource; GT6000 Mobilis helps you save it.
Extreme portability, easy setup, fast results – the Gasmet GT6000 Mobilis portable FTIR multi-Component stack gas and emission analyzer is designed for Stack Monitoring with a list of features to make you more efficient.

Key benefits include:

  • The first and only FTIR analyzer with MCERTS EN15267-4 certification
  • Intuitive user interface and ergonomic design
  • Easy to disassemble, carry, and set-up again
  • Multigas measurements in a portable package
  • Realtime results reliably and remotely
  • Exceptional robustness: shock and vibration resistivity by design
  • Smart software with self-diagnostics for easy and fast service
  • Suitable for on site or laboratory use.

Stack Monitoring Performance

For Stack Monitoring, GT6000 Mobilis setup, measurements, and analysis happen smoothly and time-efficiently. The device is simple to set up and disassemble, and there are no loose screws and other small parts that can fall while in transit or on your way to the stack. Integrated sampling line supports make it is easier to use and there are fewer parts to carry around. The device enables you to measure all key compounds at once, including oxygen with PSS Plus. For ease of use, GT6000 Mobilis gives clear OK / Not OK on the software side to indicate if the device is ready or not for measurements. The PSS on the other hand has indicator lights to tell the same thing on its part. Results are available in mere minutes.

Emission Research

For Emissions, its ease of use, multi-gas measurements, and immediate results let you focus on what is important, your research. With GT6000 Mobilis, even the smallest concentrations are measured with high accuracy. These measurements can be monitored on-site or even remotely. Results can be accessed via PC or tablet with Calcmet software. Additionally, as sometimes the measured compounds can be unexpected, with Calcmet software you can reanalyze measurement data afterward to identify these unknown gases. The system is easy to use, which reduces the need for supervision and can be used with minimal training, whether you are working in the lab or on the field.

The system is typically set up to measure H2O, CO2, CO, NO, NO2, N2O, SO2, NH3, CH4, HCl, HF and different VOCs and can measure up to 50 gases simultaneously.  Additional gases can be easily added without any hardware changes.  The corrosion-resistant sample cell is heated to 180 °C, which ensures that the sample stays in the gaseous phase even with high concentrations of H2O or corrosive gases. FTIR technology ensures that results will be available immediately on-site, and further analysis provides hard data for your specific needs.

The GT6000 Mobilis supersedes the DX4000. 

GT6000 Mobilis Data Sheet
GT6000 Mobilis Brochure

GT6000 Mobilis is designed to be used with the portable sampling system, PSS Plus or PSS Base. PSS utilizes the hot-and-wet measurement principle (no drying or dilution), which ensures that the analysis is done with a representative sample. There is two-stage particulate filtration: the first one in the sampling probe and the second one in the sampling system. The portable sampling system can be optionally equipped with a ZrO2 sensor for accurate oxygen measurement.Image of GT6000 Mobilis with Portable Sampling System

With all-new design the user experience has been taken to new heights. Integrated controls on front, 2 handles and cables in the back provide smooth operation. While PSS Base offers more basic design, for more hardcore work we have PSS Plus. PSS Plus comes with flow meters on front and has an instrument air option. This makes the system easier and cheaper for user while also providing safer operation, since nitrogen is only needed for background measurements.

 

Key benefits of PSS

  • User-friendly design
  • Instrument air option (PSS Plus)
  • Integrated controls accessible from Calcmet
  • IP42 rated.

]]> HALO RP H2O – trace level moisture analysis at reduced pressure conditions

Able to operate in a pressure range from 50 Torr to 15 psig, the HALO RP H2O moisture analyzer allows monitoring for contaminants close to the substrate or in the process chamber exhaust, significantly reducing the risk of problems that cause product yield losses.

Bulk and specialty gases may be OK at the post-purifier stage, but as gas travels through the various fab distribution systems and arrives at the equipment or process chamber, there is a risk that high partial pressures of moisture are present during processing, resulting in defects, yield loss and reliability issues.

For example, in semiconductor fabrication, moisture present in low-temperature epitaxy (LTE) can affect the quality and strain of the epi layers. In HB-LED fabrication, MOCVD processing with high moisture present in NH3, can lead to significant reduction in luminescence and yield loss.

HALO RP H2O features

  • Low parts per billion (ppb) moisture detection capability in inert, acid and hydride gases
  • Absolute measurement (freedom from calibration gases)
  • Wide dynamic range—over four orders of magnitude
  • Low cost of ownership and operational simplicity
  • Clean technology—no external calibration gases required
  • Compact analyzer footprint
  • CRDS technology, designated by SEMI-F112 06-13 Standard

Applications

  • Gas Quality Control
  • UHP Ammonia & High-Brightness LEDs
  • Research & Development
  • Semiconductor Process Tools

Process Insights also offers a new CRDS analyzer performance upgrade. Implementing dynamic data processing, the Speed+™ Analyzer Performance Upgrade Software adjusts your analyzer’s response automatically and in real-time to deliver the best performance.  Benefits of Speed+ for your operations include real-time process control to ensure quality, as well as faster throughput and increased capacity to improve efficiency and profitability.

Serani™ Max Analyzer Interface Software allows you to have remote access from your computer or laptop for our latest CRDS generation analyzers, such as the HALO KA Max and T-I Max. The Windows-based software package communicates with the analyzer through Ethernet and allows full control of the system conveniently from your desk.
