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

Core Analysis for unconventional reservoirs

by Oxford Instruments plc     based in Abingdon, UNITED KINGDOM

Low field Nuclear Magnetic Resonance (NMR) is routinely used in core analysis laboratories to examine the T2 relaxation time distribution of fluids in core plugs. These distributions can be interpreted to give information on: pore size distributions; permeability; total and effective porosity; free fluid index and bound water volumes. The partnership between Oxford Instruments and Green Imaging Technologies allows us to integrate hardware and software to enable any core analysis laboratory to generate these petrophysical results without the need for in-depth knowledge of NMR.

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.

Measurement solution for fire testing for the railway industry

by Protea Limited     based in Middlewich, UNITED KINGDOM

A lot of research is carried out in laboratory and on real fires as to the gaseous substances produced in fire effluent. Measurement principles using analytical instrumentation are becoming more widely used in fire testing, due to the quick, real-time nature of the measurements. ISO 19702 is an international standard developed for the use of FTIR analysers in the analysis of gas from fire effluents. Further to this, local test standards such as DIN 5510, applicable to the railway industry, can provide further requirements for gases to be measured.

AutoChem - Process Analytical Technology (PAT)/Quality by Design (QbD)

by Mettler - Toledo Int. Inc     based in Greifensee, SWITZERLAND

Process Analytical Technology (PAT) has been implemented for years, particularly by the chemical industry for the control of chemical processes. More recently, PAT has become a cornerstone of the US Food and Drug Administration’s (US FDA) Quality by Design (QbD) initiative for both the design and control of quality processes. For this reason, the pharmaceutical industry is also active in utilizing PAT tools. PAT tools can be implemented in both the lab and the plant, with laboratory PAT focused more on the design of a quality process and with plant PAT focused on the monitoring and control of the process.

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.
