The Importance of Using Gradient Grade HPLC Solvents versus Isocratic for Gradient Applications

April 1, 2015 8:50 am | by Bruce Herzig, Applications Scientist, EMD Millipore, Darmstadt, Germany

Despite the popularity of HPLC, it isn’t always clear which grade of solvent should be selected when performing HPLC analysis for gradient applications. Using an incorrect solvent can lead to unstable baselines, ghost peaks and perceived product quality issues. To ensure the most reliable results from HPLC analysis, it is important to choose the correct solvent grade.

Ultra-high Speed Analysis of New USP Methods

Dual-column gas chromatography meets the needs of the environmental testing industry by providing fast, accurate separation of multiple halogenated compound classes.


GC Ensures Integrity of Drinking Water in Fracking Locations

February 20, 2015 9:00 am | by Lee Marotta, Sr. Field Application Scientist, PerkinElmer Instruments, Shelton, Conn., and Robert Thomas, Scientific Solutions, Gaithersburg, Md.

Multiple gas chromatography methods are being deployed to monitor a suite of fracking-related contaminants that may be present in drinking water. 


AMS Transitions From Research to Practice

February 19, 2015 2:00 pm | by Tim Studt, Editor-in-Chief, R&D Magazine

Accelerator mass spectrometry (AMS) is an analytical technique for measuring isotope ratios with high selectivity, sensitivity and precision. Initially developed more than 75 years ago by Robert Cornog and Luis Alvarez at the Univ. of California, Berkeley, there are now more than 110 AMS systems in 28 countries around the world, mostly at government and university labs, but a few at private companies as well.


High-magnification Aids FTIR Imaging of Biomedical Tissue

As illustrated by experimental results, imaging in high-magnification mode is faster and results in more spectral and spatial detail.


NIR Spec Delivers Fast Tablet Testing

February 19, 2015 1:00 pm | by Metrohm USA, Riverview, Fla.

Near-infrared spectroscopy reduces the amount of time and work needed to test sustained-release tablets, and ensures nondestructive, reliable analysis.


Using TLC to Choose an HPLC Column

December 10, 2014 11:55 am | by Fred Rabel, Owner, ChromHELP, LLC, Woodbury, N.J.

Because of the high cost of HPLC columns, there are numerous ways to find out which column(s) might best be of use for an intended but new separation. If some of the components are known, then the literature or manufacturers’ websites can be consulted. This might take some time, but the research of others can save both time and money in your own work.


pH Gradient Speeds Separation of Antibodies

December 10, 2014 11:47 am | by Ken Cook, Frank Steiner, Mauro De Pra, Thermo Fisher Scientific, Inc.

Pre-formulated buffers for pH gradient have greatly simplified the development of ion exchange chromatography (IEX) of monoclonal antibodies (mAbs). Three features make this simplification possible.


Soft Ionization Drives Future GCMS Technology

December 10, 2014 11:37 am | by Laura McGregor, Nick Bukowski and David Barden, Markes International, UK

Soft ionization remains a relatively underused technique for GCMS, despite its ability to provide improved confidence in the identification of a range of challenging analytes. But there is now a new approach that makes it possible to lower the energy of electron ionization to achieve soft ionization, without the disadvantages with which it has historically been associated.


Higher Performance, Smaller Sizes Define Future Mass Spec

December 10, 2014 11:23 am | by Sarah Smith, Global Market Manager, Analytical, Bal Seal Engineering Inc., Foothill Ranch, Calif.

Mass spectrometry (MS) is the workhorse of analytical chemistry. It performs the analysis of the sample, making MS equipment an essential part of the analytical instrumentation market. A recent shift in the laboratory landscape, however, is forcing a change in the size and functionality of mass spec equipment.


What a Single Drop of Blood Can Reveal
