Featured Application Note:
Analysis of Acetaminophen
Nicole Kreuziger Keppy, Gordon Bain, Ph.D., and Michael W. Allen, Ph.D., Thermo Fisher Scientific
FT-IR
FT-IR Analysis of Contaminants in Foods
Shimadzu Scientific Instruments, Inc.
Identification and qualitative characterization of a foreign material is essential for defining the cause of contamination; FT-IR spectroscopy is one of the quickest and the easiest means of accomplishing this.
 
Analysis of Individual Red Blood Cells by UV Microscopy and Microspectroscopy
Dr. Paul Martin, CRAIC Technologies, Inc.
Single red blood cells are imaged with a UV microscope and then UV-visible-NIR spectra are obtained using a UV-visible-NIR microspectrophotometer.
 
Applications of 1064 nm Dispersive Raman Systems in Biofuel Research
Eric Bergles and William Yang, BaySpec, Inc.
BaySpec, Inc. has developed a complete line of 1064 nm excitation, dispersive Raman systems that offer maximum reduction in fluorescence interference from biological samples and thus making them very useful tools for biofuel research.
 
Mapping Protein Conformational Stability Using Automated CD
Lindsay Cole and David Gregson, Applied Photophysics Limited
A new automated technique is described for measuring protein conformation. Superb reproducibility enables relative protein stabilities to be studied with ease, for example in protein biotherapeutic development and clone selection procedures.
 
Generating Purge Gas for FT-IR Spectroscopy
Peter Froehlich, Parker Balston
Water vapor and CO2 in the FT-IR sample chamber lead to additional peaks that obscure information. These can be eliminated by sealing the sample chamber and purging with dry, CO2 free air/nitrogen.
 
Analysis of Acetaminophen
Nicole Kreuziger Keppy, Gordon Bain, Ph.D., and Michael W. Allen, Ph.D., Thermo Fisher Scientific
In this application note, the quantity and percent assay of acetaminophen is determined according to USP methods.
 
Wine Color Analysis
Gordon Bain, Ph.D., Thermo Fisher Scientific
The ability to measure all wavelengths from 190-100 nm simultaneously makes the Evolution Array UV-vis system ideal for performing quality control measurements for wine color.
 
The Determination of HMF in Honey
Nicole Kreuziger Keppy and Michael W. Allen, Ph.D., Thermo Fisher Scientific
Nicole Kreuziger Keppy and Michael W. Allen, Ph.D., Thermo Fisher Scientific Hydroxymethylfurfural, or HMF, is an aldehyde that is often used as an indicator for the quality of honey. The HMF content of honey is determined by the White Method quickly and easily with an Evolution Array UV-vis spectrophotometerr.
 
Analysis of Amino-terminated Organic Films and Protein Immobilization by FT-IR and Ellipsometry
Joonyeong Kim, Thermo Fisher Scientific
This note discusses the use of ellipsometry and FT-IR with grazing angle attenuated total reflectance in monitoring derivatizations of chemically reactive amino groups on APTES thin films followed by the site-selected immobilization of proteins.
 
100-nm IR Spectroscopy: Analyzing Polymeric Materials
Kevin Kjoller, Craig Prater, Mike Lo, and Roshan Shetty, Anasys Instruments; Curtis Marcott, Light Light Solutions
This note discusses the scientific breakthrough technique, which enables a 100x improvement over diffraction limited spatial resolution for IR while generating spectra that can be correlated to FT-IR libraries. It also provides simultaneous nanoscale mechanical property information.
QAQC
Analysis of Elemental Impurities in Pharmaceutical Products
Matthew Cassap, Thermo Fisher Scientific
This application note demonstrates the analysis of pharmaceuticals using ICP-OES, which is one of the two methods proposed by the United States Pharmacopeia (USP). Find out how to prepare your laboratory to these proposals.
 
Determination of Hg in Environmental Samples Using a Direct Mercury Analyzer
Johan Nortje, Milestone, Inc.
Describes a technique for successful determination of mercury in environmental matrices. Direct mercury analysis delivers accurate, reproducible results in approximately 6 min and requires no sample preparation prior to analysis.
