Biodiesel-Blend Analysis by FT-IR (ASTM D7371 and EN 14078)
By Ben Perston and Nick Harris
This application note illustrates the implementation of methods ASTM D7371 and EN 14078 for biodiesel-blend analysis in the PerkinElmer® Biodiesel IR FAME Analyzer.
 
Diamond ATR and Calibration Transfer for Biodiesel-Blend Analysis by ASTM D7371
By Ben Perston and Nick Harris
Biodiesel consists of FAMEs produced from vegetable oils or animal fats via a transesterification reaction. This application note demonstrates the suitability of the PerkinElmer® Universal ATR accessory for this analysis.
 
Simple Method of Measuring the Band Gap Energy Value of TiO2 in the Powder Form using a UV/Vis/NIR Spectrometer
By Jayant Dharma, Aniruddha Pisal
The measurement of the band gap of materials is important for the semiconductor, nanomaterial and solar industries. This application note describes how the LAMBDA™ 1050 UV/Vis/NIR can optimize this methodology.
 
Determination of Oil and Grease in Water with a Mid-Infrared Spectrometer
By Aniruddha Pisal
This application note presents the method developed for the analysis of oil and grease in water using tetrachloroethylene extraction followed by mid-infrared (mid-IR) spectrometry.
 
Characterization of Soil Pollution by TG-IR Analysis
By Ben Perston,Robert Packer, Maria Garavaglia
Thermogravimetric analysis coupled to infrared spectroscopy (TG-IR) provides detailed information about the amount and nature of the pollution, while requiring no sample preparation at all.

Atomic

By Praveen Sarojam
This application note demonstrates the ability of AAnalyst™ 800 spectrophotometer in analyzing a variety of fish samples for trace-metal contamination according to AOAC Methods 999.10 and 999.11.
Mass Spec
Qualitative Analysis of Evolved Gases in Thermogravimetry by Gas Chromatography/Mass Spectrometry
By Bill Goodman, Greg Johnson, Kevin Menard
This application note demonstrates the benefits of thermogravimetric analysis coupled to GC/MS (TG-GC/MS) in the separation and identification of complex mixtures of gas evolved during a TGA analysis.
 
Evolved Gas Analysis: Residual Solvent Contamination Measured by Thermogravimetric Analysis-Mass Spectrometry

This application brief demonstrates the benefit of coupling a mass spectrometer to a thermogravimetric analyzer (TG-MS), allowing evolved gases to be analyzed for complete characterization of the sample.
