Application Notes: General
Enhanced Raman Reflection Spectroscopy for Process Analytical Technology
February 17th 2016A novel approach in Raman spectroscopy enables bulk material analysis without the need for specialized equipment. Enhanced Raman reflection can be integrated into current processes using available instrumentation, enabling real-time process measurement and control.
Determination of the Degree of Cure of a Varnish
January 8th 2016Modern paints and varnishes are complex mixtures and the optimization of the material properties is an important task. One of the most essential variables is the curing which should in most cases take place in a reasonably short time span that can range from a fraction of a second to many days. It is difficult to evaluate the degree of the curing and its completeness by visual inspection. Therefore, an unbiased and reliable quantitative analysis is needed in quality control but also in R&D to optimize the varnish or the curing method respectively.
Using Multivariate Curve Resolution to Identify the Evolved Gases Created During a TGA-IR Experiment
September 1st 2014Thermal decomposition provides valuable information about the chemical composition of a material. Although thermal gravimetric analysis (TGA) measures small weight losses during a heating ramp, it cannot identify the chemicals corresponding to the weight loss.
Simultaneous Single Reaction Chamber Microwave Digestion of Mixed-Consumer Products
September 1st 2014Milestone's UltraWAVE microwave digestion system with single reaction chamber (SRC) technology, enables the simultaneous digestion of up of to 22 different sample types and chemistries at temperatures and pressures as high as 300 ?C and 199 bar.
Chemical Analysis of Microscopic Fluorescent Materials by Dispersive 1064 Raman System
September 1st 2014Raman measurement on microscopic inclusions in fluorescent materials requires the ability to measure in small volumes, excellent throughput, and long wavelength excitation such as 1064 nm for fluorescence reduction.
Using the Full Spectrum for Raman: From UV to NIR
The "inelastic scattering of light," or Raman effect, was observed in practice for the first time in 1928 by C.V. Raman for which he was awarded the Nobel Prize in 1930.
Determination of Sodium Lauryl Sulfate and Sodium Laureth Sulfate in Commercial Body Care Products
September 1st 2014A method for quantifying the percent sulfate associated with sodium lauryl sulfate (also referred to as sodium dodecyl sulfate) and sodium laureth sulfate (also referred to as sodium lauryl ether sulfate) found in commonly used commercial body care products using FT-IR attenuated total reflectance (ATR) spectroscopy is outlined.
Lanthanide Series Investigations with TSI LIBS Desktop Analyzer
September 1st 2014The lanthanide series is a series of metallic elements, with atomic numbers 58 through 71, which are - in order of increasing atomic number - cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium.
