Integrated real-time gas analysis solution for specialty gases industry

by CIC Photonics, Inc.     based in Albuquerque, NEW MEXICO (USA)

CIC Photonics’ extensive experience with gas analysis has also included what the industry refers to as Specialty Gases, as distinguished from Semi Gases, Electronic Specialty Gases, and Industrial Gases. Specialty Gases are high purity gases used across many applications by researchers, by government agencies, and by commercial businesses. Included among these users and applications are: hospitals for medical gases; environmental labs and testing companies for blends of protocol gas mixtures; calibration gases; spectroscopy standards; gas composition measurements and confirmations; and others.

Cloud Point of Diesel Fuel #3074

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

The Cloud Point of a diesel fuel is the temperature below which wax forms giving the fuel a cloudy appearance. This parameter is an important property of the fuel since the presence of solidified waxes can clog filters and negatively impact engine performance. The traditional laboratory methods for the measurement of Cloud Point are optical in nature, but rely on cooling the fuel for the wax formation to occur. Guided Wave’s process analyzers can measure compositional changes in the fuel that will be directly related to the wax formation and hence the Cloud Point. This note will discuss the use of Guided Wave hardware and software tools for the measurement of the Cloud Point of diesel fuel using fiber optic-based, near-infrared (NIR) spectroscopy. NIR can be applied in real time directly in process.

Axetris infrared sources are used in a variety of medical applications: Anesthesia Monitoring, Capnography, Blood Gas Analysis, Pulmonary Diagnostic.

Measurement solution for hospital workplace exposure monitoring

by Protea Limited     based in Middlewich, UNITED KINGDOM

In taking a responsible stance on the exposure of workers to any potentially hazardous gases, there is a need for workplaces using anaesthetic gases, such as hospital operating rooms or research laboratories, to control the level of waste anaesthetic gas in the ambient air.

Integrated real-time gas analysis solution for electronic specialty gases industry

by CIC Photonics, Inc.     based in Albuquerque, NEW MEXICO (USA)

The company’s entry into the electronic specialty gas market originated in 1994-95 as a consequence of the semiconductor industry’s demand for increasingly higher purity gases from the major gas producers. The issue was then and remains today to be primarily moisture impurity levels in the cleaning, etching, and treatment gases used in wafer production. In that earlier period when common wafer sizes were 6” and 12”, the semi industry required moisture concentrations to be 250 to 500 ppb or better; with each year after that the industry tightened its requirements such that today the moisture specifications are 1 to 5 ppb or better.

Infrared Sources for Anesthesia Monitoring

by Axetris Ag     based in Kaegiswil, SWITZERLAND

Anesthesia agent monitoring identifies and quantifies the anesthesia. This is done by using infrared absorption techniques to control the phases of the anesthesia. Therefore several gases have to be measured at once – online, accurately and reliably.

Gas Detection Solutions for Fertilizer Manufacturing

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example, water vapor) – such interferences complicate other optical techniques using IR or UV.

Octane Number of Gasoline using NIR Spectroscopy #3012

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

When every second counts and performance is on the line Guided Wave's NIR analyzers allow for easy measurement of octane numbers in gasoline and refinery production units using fiber optic -based, near-infrared (NIR) spectroscopy. *Fast and reliable measurement of the octane number of gasoline (RON & MON). * Control gasoline production in real-time directly with in process monitoring. * Certify gasoline meets specification before release. *Gain significant improvements in process control. *Minimize the need for laboratory sample collection and the labor intensive "knock engine" method. The measurement of the octane number of gasoline using NIR spectroscopy is both fast and reliable utilizing Guided Wave analyzers. Results are available in real-time (seconds) for multiple parameters in complex streams. Request Application Note #3012

Sub-ppm Oil in Water Testing

by Spectro Scientific     based in Chelmsford, MASSACHUSETTS (USA)

InfraCal 2 is the newest addition to the worldwide-recognized Wilks InfraCal line of portable, filter-based infrared analyzers. It provides sub-ppm measurement capability, password protected calibrations and instrument settings, data storage and multiple calibrations, and a touch screen display for more user options. Ideal for measuring oil content levels in FRAC and produced water, fats, oil and grease (FOG) in wastewater, industrial and refinery wastewater effluents, cleaning of metal parats, drill cuttings, containment ponds and remediation sites.

Gas Detection Solutions for Liquified Natural Gas Detection

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

Liquefied natural gas owners require improved routine monitoring of facilities for safety, economic and regulatory reasons. Leaking LNG can cause explosions leading to loss of life and property. Loss of product through undetected leaks dramatically reduces a pipeline operator’s profitability. Traditional gas detectors are slow to reach and require a labour intensive process to keep maintained. IR detectors have been used but with limited success because of cross interference from other atmospheric gases.

Measurement solution for hydrogen fuel cell testing

by Protea Limited     based in Middlewich, UNITED KINGDOM

As the alternatives to fossil fuels for power generation and automotive power become more widespread and preferred, so has increased the research and testing of hydrogen gas in fuel cells. The hydrogen (H2) gas used in fuel cell has to be free of impurities in order to make the fuel cell as efficient as possible and so quality thresholds have been set in legislation. Such legislation as SAE J2719 provides hydrogen fuel quality standards for proton exchange membrane (PEM) fuel cell vehicles. If impurities above these thresholds are present in the H2 fuel then there is a risk of not only making the cell inefficient, but also unrecoverable back to its peak operating voltage as the fuel cell electrode becomes poisoned.

Measurement solution for on-line carbon bed system

by Protea Limited     based in Middlewich, UNITED KINGDOM

Commonly, activated carbon beds are used as abatement systems on plant, with emissions being reduced by adsorption onto the bed. The efficiency of any abatement system is critical to its operation, not just in ensuring emissions are reduced as much as possible, but an efficient bed has cost savings for the operator.
