VOC Analysis of Water-Based Coatings by Headspace-Gas Chromatography
2008|PerkinElmer|Aplikace
Headspace as a technique for analyzing VOCs in water-based coatings is often limited by the need to analyze for glycols. Within headspace, there are two common mechanisms for collecting a sample aliquot of known volume. The first, more common technique…

Biodiesel Glycerin and Methanol Analyzer
2008|PerkinElmer|Brožury a specifikace
In the production of biodiesel, free fatty acids (lipids) are catalytically converted to fatty acid methyl esters (FAME) with alcohol, typically methanol. Following this reaction, glycerin, water and residual catalyst must be removed to create a fuel suitable for use…
