Since the Montreal Protocol banned the production of Freon-113, it became necessary to find a suitable replacement solvent or solvents for measuring total oil and grease (TOG) and total petroleum hydrocarbon (TPH) levels in water and soil using infrared analysis. We studied potential candidates for Freon replacement and found several that are usable. In addition, ASTM approved S-316 as a ...
Specifically designed for oxygen measurement in chemical solvent incinerators, the ATS/D-EUT is distinguished by its ability to eliminate any risk of acidic condensate formation. Its lifespan exceeds typical industrial use ...

The NIRS XDS Transmission OptiProbe Analyzer enables straightforward determination the content of aqueous products, clear liquids, solvents, and viscous samples. The analyzer is suited for use in the technical center as well as for atline applications in the scale-up of production processes. ...
This program first discusses the Beer’s Law basis for quantitative absorption spectroscopy. It considers choice of band, solvent, concentration, pathlength, baseline and calibration curve. Next, measurement errors are classified as physical, chemical or instrumental and their effects on precision and accuracy considered. Single and multicomponent analyses are discussed and an actual 5 ...
The Whisper nitrogen generator has been developed to meet specific requirements in terms of flow, purity and pressure in LCMS applications. The Whisper nitrogen generator has been developed to meet specific requirements in terms of flow, purity and pressure in LCMS applications. It can also be used for the evaporation of solvents in samples being analyzed. The simple high efficiency membrane ...
The contaminant of concern was Stoddard solvent used by the United States Army as a dry cleaning fluid. The Stoddard solvent had been stored in underground storage tanks located between building 228 and the retaining wall. A clean up goal of 100 mg/kg of Stoddard solvent analyzed as gasoline range petroleum hydrocarbons was ...
The Membrane Nitrogen generator has been developed to meet specific requirements in terms of flow, purity and pressure for LC-MS applications. It can also be used for the evaporation of solvents in samples being analysed. The simple high efficiency membrane technology allows the separation of nitrogen from the other components of the compressed air ...

It can accurately monitor a given range of solvents within a narrow band to optimize both the safety and the economy of running a process; it can also be used for mixtures of solvents in processes where normal solvent concentrations are below 25% LFL. This analyzer was built on a robust and well-proven industrial ...

Sterically unhindered primary alcohols are usually completely derivatized at room temperature within minutes.4 The silyl reagent often serves as the solvent. Nonpolar organic solvents, such as hexane, ether, benzene, and toluene are excellent solvents for the reagent since their reaction byprod-ucts do not accelerate the rate of reaction. ...
The extract was then decanted into a quartz cuvette that wasplaced in the chamber of the fluorometer. The extract was analyzed, and the device displayed the TPH concentration in partsper million, which is equivalent to a soil concentration in milligrams per kilogram. ...
