Integrated real-time gas analysis solution for emissions industry

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

Pollutant emissions from industrial smoke stacks are a major national concern due to both health concerns and climate change. As a consequence, there are at least tens of gas analyzer manufacturers in the U.S. alone that compete in that market and have done so for years. What CIC Photonics brings to that competitive field is its expertise derived from its Combustion Efficiency Solution and its high performance IRGAS Systems. The IRGAS-CEM provides real-time and simultaneous measurements of the multitude of toxic combustion products, including CO, CO2, NOx, SOx, CH4, CxHy, H2S, etc. The EP-IRGAS-SPA is also applicable for fast time responses.

Formaldehyde and Acetaldehyde Determination in Air Using Fully Automated On-Line Desorption and Analysis of DNPH Cartridges

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

Airborne aldehydes and ketones are collected by passing air through a cartridge containing 2,4-dinitrophenylhydrazine (DNPH). Carbonyl compounds react with the DNPH to form hydrazones, which are immobilized on the cartridge. These compounds can be easily eluted from the cartridge with acetonitrile and analyzed by HPLC with UV detection. Traditionally, this analysis including the workup contains a series of manual steps, which can become time-consuming and could incur experimental error. Automating the extraction of LpDNPH S10 cartridges and putting it in-line with the HPLC analysis will significantly reduce manual labor using this technique and this will improve reproducibility of the method by reducing potential experimental errors by the operator. The automation and unattended operation of the method leads to high throughput for determining airborne formaldehyde and acetaldehyde.

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.

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.

Integrated real-time gas analysis solution for semi-gases industry

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

CIC Photonics first applied its IRGAS technology to semi-gases when a major semiconductor equipment manufacturer, Applied Materials, requested a demo of its capability to monitor gas quality for epitaxial reactor applications; that was in year 2000. The IRGAS System met all of the technical requirements, which included ppb sensitivity for moisture as an impurity, gas cell chemical resistance to both acid and basic semi-gases, and fast concentration tracking time response.

XRF analysis for lead paint

Measurement of diacetyl in ambient air to monitor workplace exposure limits.

by MOCON - Baseline     based in Lyons, COLORADO (USA)

The Series 8900 Diacetyl Analyzer provides direct measurement of Diacetyl in ambient air. This instrument is utilized for environmental monitoring and to monitor workplace exposure limits. The Series 8900 Analyzer for Diacetyl employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Diacetyl and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. The Diacetyl is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Ambient air monitoring by FID detection – airmoVOC BTEX

by Chromatotec Group     based in Val de Virvée, FRANCE

Urban pollution is a problem that concerns more and more people in charge of public health. In large cities, car emissions are an important source of atmospheric pollution. This problem is growing as the traffic keeps on increasing. BTEX compounds are present in car emissions. It is therefore important to be able to analyze them with short analysis cycle duration and on a continuous and automatic way.

Saran Bag application

by Analytical Specialties, Inc.     based in Elburn, ILLINOIS (USA)

Title : Preliminary Sampling Methodology and Analytical Procedures for Ambient Sulfur Hexafluoride, Corporate Author : ARMY MEDICAL ENVIRONMENTAL ENGINEERING RESEARCH UNIT EDGEWOOD ARSENAL MD Personal Author(s) : Luckan,Susan K. ; Cooper,William J. Report Date : JAN 1973 Pagination or Media Count : 23 Abstract : A preliminary evaluation of techniques of sampling and gas chromatographic analysis for low levels of sulfur hexafluoride was conducted to determine the most feasible method for available equipment. Using a Tracor MT-150 gas chromatograph equipped with Nickel 63 electron capture detector and polarized dc voltable, it was possible to detect sulfur hexafluoride at a concentration of 0.06 ppb with a 5A molecular sieve column and nitrogen carrier gas, without preconcentration of the sample. Also, a comparison of glass and Saran sampling materials proved that no detectable loss of the tracer gas resulted with the Saran bags (between 6 ppm and 0.06 ppb SF6
