Analysis of Trace Elements in Naphtha
By Matthew Cassap, Thermo Fisher Scientific
The analysis of trace metals in naphtha is important in the cracking of hydrocarbons. The presence trace metals can severely impede this process and can poison catalysts. This application note explains how to analyse naphtha easily using the Thermo Scientific iCAP 6500 Radial ICP
 
Detection of hydrocarbon radicals during plasma etching
By T.A.R. Hansen and R.Engeln, Avantes
Optical emission spectroscopy is used to study and monitor the plasma etching of hydrogenated amorphous carbon (a-C:H) thin films.

Determination of Low Concentration Methanol in Alcohol by Affordable High Sensitivity Raman Instrument
By Enwave Optronics, Inc.
Here, Enwave presents a Raman spectroscopy method for a quick and lower cost alternative to verify the existence of low concentration methanol in alcohol.
 
New Approach for Optimizing a Monoclonal Antibody Biotherapeutic in Different Formulations
By David Gregson & Lindsay Cole, Applied Photophysics Limited
The new technique of dynamic multi-mode spectroscopy (DMS) was used to study the stability of a monoclonal antibody biotherapeutic formulated in acetate and lactate buffers.
 
Crystallinity determination by XRD
By Dr. Detlef Beckers, Dr. Ingeborg Fix, and Prof. Dr. K.- J. Steffens, PANalytical, Inc.
This application note compares the use of three different methods - X-ray diffraction (XRD), near infrared spectroscopy (NIRS), and differential scanning calorimetry (DSC) - for quantifying small amounts of amorphous material in a crystalline matrix, and vice versa. Emphasis is placed on comparing the precision, accuracy, detection limit, and speed of measurement of the different methods.
 
Wide-field Raman Chemical Imaging for Ingredient-Specific Particle Sizing
By Ryan J. Priore, ChemImage Corporation
Wide-Field Raman Chemical Imaging is used to provide simultaneous spatial and spectral information that is key to measuring the drug particle size distribution within many drug delivery systems.
