PYREX HPLC Mobile Phase Reservoir, Single Cavity

Mobile Phase Reservoirs from Corning

Lab Innovations 2013

The experimental design that considers gradient time and temperature was expanded to include a third factor, either pH or ternary composition, and modelling software facilitated the analysis.

The parameters that should be considered in the optimization of HPLC methods are explained and then illustrated through the analysis of two commercial agricultural products.

Supercritical fluid chromatography has become a viable option for the separation scientist in diverse areas, and the field now seems more adequately described as an extension of HPLC, or perhaps as "carbon dioxide–based HPLC".

The authors explain modern UHPLC instrument design and outline simple procedures to identify causes of poor column and method performance.

When choosing the articles to include in this supplement, my selection was based on a very simple criterion.

The innovative and inspiring career of Barry Karger is described, including his pioneering work in bioanalysis.

There are many parameters that need to be considered when considering the use of hydrogen as a carrier, however, the benefits to chromatography and money saved make this a worthwhile exercise.

In any field, there are "misconceptions" or "myths" that arise and are perpetuated and passed on to the next generation. These myths are often driven by a lack of understanding of the real issues by practitioners. In the first of a two-part feature from Ron Majors, the top 10 high performance liquid chromatography (HPLC) column myths are presented and attempts are made to demystify them by offering some evidence that they are untrue. This part will feature myths 10 to six.

The Eastern Analytical Symposium (EAS) will be held this year from November 18 to 20, 2013, in Somerset, New Jersey. EAS is the second largest conference and exposition for laboratory science in the United States dedicated to the needs of analytical chemists and those in the allied sciences.

There are many parameters that need to be considered when considering the use of hydrogen as a carrier. Even so, the benefits to chromatography and money saving make this a worthwhile exercise.

Highlights of the column technology observed at the symposium

The latest applications for carbon nanotubes in chromatography and sample preparation are outlined.

A tribute to John Dolan, who is celebrating 30 years of writing the "LC Troubleshooting" column.

The application of gas chromatography (GC) combined with atmospheric pressure chemical ionization mass spectrometry (GC–APCI-MS) and with supersonic molecular beam ionization mass spectrometry (GC–SMB-MS).

What's happened in the last 30 years? What will happen next?

The Viscotek SEC-MALS 20 multi-angle light scattering detector measures absolute molecular weight and size (Rg) of proteins and polymers. Its 20 detector array and vertical flow cell ensure exceptional accuracy.

Tosoh Bioscience expands the renowned TSKgel SW series of aqueous size exclusion HPLC columns by three new UHPLC columns, tailored to different aspects of antibody analysis.

AkzoNobel presents its latest preparative HPLC product, Kromasil EternityXT, an extension of the Eternity grafted technology platform, a material with an extended lifetime for preparative applications under extremely demanding conditions.
