Recent Developments in Microchip Electrophoresis

Capillary electrophoresis (CE) is routinely used for chemical and biochemical analysis methods, and recently the technique has been implemented on microchips. R. Scott Martin, a professor and chair of chemistry at Saint Louis University, has been investigating ways to improve these techniques for years. He recently spoke to us about his research coupling microchip electrophoresis with electrochemical detection, coupling continuous flow with microchip electrophoresis with valving, coupling microchip CE with microdialysis sampling and electrochemistry, and more.

The Heightened Role of HILIC in Biopharmaceutical Analysis

Valentina D’Atri from the University of Geneva spoke to The Column about the evolving role of HILIC in biopharmaceutical analysis.

Accurate Determination of Methane in Cable Insulation Material by Gas Bag Sampling and Multiple Headspace Extraction Gas Chromatography

By Clive Ji, Jian Zou, Yabin Sun, Changkan Zheng, Grace Yang

A method was developed to address the constraints encountered when measuring methane levels during the degassing process.

Effects of External Influences on GC Results

By John V. Hinshaw

If you understand how your system is affected by outside influences, you can take control of the variables.

New Advice on an Old Topic: Buffers in Reversed-Phase HPLC

By Sharon Lupo, Ty Kahler

A model set of analytes and selected applications are used to demonstrate the effects that buffers can have on the selectivity of a separation and the sensitivity of a reversed-phase analysis when using MS detection.

Analysis of Organic Compounds in Water Using Unique Concentration–Injection Techniques for Portable GC–MS

By Tai V. Truong, Thy X. Truong, Nathan L. Porter, Edgar D. Lee, Milton L. Lee

In this study, a simple method was used for extraction and concentration of trace organic compounds in water, followed by injection using a coiled wire filament and GC–MS analysis. Common semivolatile organic compound contaminants at low parts-per-billion levels were detected in less than 10 min.

Electrophoretic Concentration—A Simple and Green Approach for Sample Preparation

By Alain Wuethrich, Paul R. Haddad, Joselito P. Quirino

We explain the principles of EC and demonstrate its use to enrich anionic pollutants and cationic drugs in environmental samples.

The Use of Extraction Technologies in Food Safety Studies

By Doug Raynie, Changling Qiu

New extraction techniques can improve the accuracy and precision of analytical results and simplify analytical procedures.

The LCGC Blog: Automated Method Development in Liquid Chromatography

By Kevin A. Schug

The ability to rapidly screen stationary phases through column-switching capabilities provides significantly greater efficiency in method development than was previously possible. The approach does require some additional hardware and software. And, while such capabilities may limit the ability to expand one’s literary knowledge during excessive months in the laboratory developing separation methods, real progress to key decision points for method optimization can be realized instead.

The LCGC Blog: Going Back in Time – Ternary and Quaternary Gradients

By Tony Taylor

Until recently, I hadn’t heard of ternary or quaternary gradients being used for many years. They have gained a reputation for being somewhat difficult to reproduce—less robust, if you like.

10 Ways to Break Your LC-MS

If there’s one mantra that’s essential for an LC (or GC)-MS operator it’s “contamination, contamination, contamination”. Keep contamination to a minimum and you’ll enjoy a reliable instrument; don’t take the necessary precautions and instead you’ll enjoy reaching for the vent switch and purchasing lots of spares.
