HILIC: An Alternative Approach for Separating Highly Polar Analytes
Hydrophilic interaction chromatography (HILIC) is an alternative separation technique for highly polar analytes that are weakly retained in reversed-phase high performance liquid chromatography (HPLC). Participants in this HILIC Technology Forum are William Long of Agilent Technologies, Phil Koerner and Carl Sanchez of Phenomenex, and Nicole M. Cotta of Waters Corp.
ALEXYS™ Neurotransmitter Analyzers
For superior sensitivity in neurotransmitter analysis, Antec provides dedicated ALEXYS Analyzers based on (U)HPLC with Electrochemical Detection (ECD) for monoamines and metabolites, GABA, Glutamate and Acetylcholine. Different instrument configurations are available to achieve highest sensitivity and/or speed of analysis using less than 10 µL of sample. For monoamines and metabolites a dual-channel HPLC/ECD system has been developed with detection limits as low as 0.2 fmol

New Upchurch Scientific® PEEK™-Lined Stainless Steel Tubing
IDEX Health & Science introduces new Upchurch Scientific® PEEK™-Lined Stainless Steel (PLS) Tubing.  The metal-free, all-PEEK fluid path withstands pressures to 15,000 psi (1,035 bar), making it the ideal choice for biocompatible UHPLC applications. Coupling the chemical compatibility of PEEK with the strength of stainless steel, other innovative design features of PLS tubing also assures better overall dimensional tolerances (±5-15 µm, depending upon the inner diameter) over traditional PEEK tubing or stainless steel
LC Columns for Biomolecule Separations
Analytical and nano scale Thermo Scientific™ Accucore™ 150-C18 and 150-C4 columns are rugged and easy to use.  The 150 Å solid core phases offer superb biomolecule separations at low backpressures.Learn more
Absolute Molecular Weight Detector
The miniDAWN® TREOS™ is a multi-angle (three-angle) light scattering detector that can be coupled to any liquid chromatograph (HPLC/GPC/SEC/FPLC) or used off-line in a "micro-batch" mode for determining the absolute molecular weights and sizes of polymers or biopolymers directly, without resorting to column calibration or reference standards.

Editors' Series: Turning up The Heat: Optimizing Temperature in Liquid Chromatography
Tuesday, November 27, 2012
9:00 AM EST; 15:00 (GMT + 1)
The use of high temperature in HPLC is very limited because of a general feeling that;
  • Stationary phases are not stable at elevated temperatures.
  • Compounds will thermally degrade at elevated temperatures.
Editors' Series: Gas Chromatography with Single- and Triple-Quadrupole Mass Spectrometry: Principles, Potential, Limitations, and Applications
Tuesday, November 27, 2012
11:00 AM EST
In this web seminar, we will describe and critically compare the use of comprehensive two-dimensional (2D) gas chromatography (GC×GC) with a single-quadrupole mass spectrometer (MS), against one-dimensional GC in combination with a triple-quadrupole (QQQ) mass spectrometry instrument. The benefits and disadvantages of each methodology will be discussed, illustrated by examples from the field of food analysis. Also, the combination of GC×GC with a triple-quadrupole mass spectrometer will be discussed, along with a series of significant applications. The emphasis will not only be devoted to the potential of GC×GC-QQQ MS, but also to the following question: Does such a combination make sense?
Increasing the Scope of Your Analytical Toolbox with UltraPerformance Convergence Chromatography UPC²
Wednesday, November 28, 2012
9:00 AM EST; 15:00 (GMT + 1)
Do you know what your next sample will be? Could it be hydrophobic, hydrophilic, volatile, nonvolatile or chiral? Are you being challenged to reduce toxic solvent waste and go green? Which technique will you choose from your analytical toolbox to get the best possible separation? In this webcast series, we will be discussing how analytical laboratories can benefit from UltraPerformance Convergence Chromatography UPC² a new category of separation science that provides an exponential increase in performance and selectivity to the chromatographic laboratory.
