Measurement of ethylene oxide for monitoring workplace exposure limits

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

The Series 8900 Ethylene Oxide Analyzer combines the selectivity of gas chromatography with the sensitivity of a Photoionization Detector (PID) providing interference free response to Ethylene Oxide (EtO) at levels below 0.05 ppm. This analytical method is referenced in OSHA`s `Occupational Exposure to Ethylene Oxide: Final Standard` 29 CFR Part 1910. The system documents exposure levels including: time-weighted averages (TWA), short-term exposure limits (STEL) and instantaneous alarms. Areas that are typically monitored include; EtO Sources - gas storage areas, sterilizer doors, aeration doors, and the General Work Area - decontamination, packaging and preparation and sterile product storage areas.

Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

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

Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are unsuccessful in retaining these small polar compounds. Therefore, most HPLC methods utilize ion-exchange resins for analysis. Another common method involves GC analysis after the analytes first undergo a derivatization step. The purpose of the work shown in this article was to develop a simple and fast analytical method to determine the levels of 2-methylimidazole and 4-methylimidazole in caramel colored carbonated beverages.

Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

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

Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air. We investigated the performance of the LC-MS and LC-MS-MS methods in the analysis of isocyanates using the new ASSET™ EZ4-NCO Dry Sampler. We found that the analytical method can successfully reach the quantitation limit for most isocyanates of 5 ng/mL in the final sample when LC-MS-MS analysis was used and the quantitation limit of 10 ng/mL when LC-MS analysis was used. All 11 compounds were well-resolved chromatographically using a 15 cm Ascentis Express C18 column.

Percent Aromatics in Gasoline #3008

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

The aromatic content of gasoline determines many of its combustion properties. Since it also impacts the environmental characteristics of the fuel it is desirable to have accurate measurements of this parameter. The traditional analytical method for measuring aromatics is either gas chromatography (GC) or an older method entitled fluorescent indicator adsorption (FIA), both of which are time and labor intensive. This note will discuss the use of Guided Wave hardware and software tools for the measurement of % aromatics in fuel products using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process monitoring or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods.

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

Environmental Monitoring

by MicruX Technologies     based in Oviedo, SPAIN

Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.

This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.

Although applications in this area advance, there is still a clear demand to get new portable and versatile analysis systems for many different application fields such as pollution in environmental or waste waters, monitoring nutrients in agricultural or horticultural water as well as general process control in chemistry industry. Because of the number of enviromental analysis required, there is a need for screening and monitoring measurements of these compounds at contaminated areas.

Traditional monitoring techniques are typically based on laboratory analysis of field-collected samples that require considerable effort and expense, and the sample may change before analysis. Moreover, the equipment currently available is too large and expensive and it cannot be made portable.Alternatively, microfluidic and electrochemical sensor technologies can contribute to the development of new portable monitoring systems, complementing standard analytical methods for different environmental monitoring applications.In this way, the decentralization and integration of all those typical analyses is the paramount importance in order to reduce cost, simplify the analytical process and make more accessible these technologies to end-users. The development of portable, robust, and accurate Lab-on-a-Chip systems to monitor priority compounds such as contaminants, explosives, chemical warfare agents, inorganic and organic ions is a demand of modern society. Portability allows analyses to be carried out outside of the laboratory, minimizing the risk of contaminating the sample and leading to a faster response time at a lower cost.

Thus, MicruX solutions and technologies open the gate to develop portable and esay-handly Lab-on-a-Chip devices in order to improve pollutants in-situ analysis in a very economic and efficient way.
