Digital Update
The Virtual Environmental Mass Spectrometry conference (VEMS 2009) will take place online at analyticalmethodology.co.uk in March–April 2009 and is designed to act as a precursor for the "real" EMS 2010 conference, provisionally proposed for 2010.
The themes for the meeting have yet to be finalized. However, abstracts (< 50 Kb) for Applications of Environmental Mass Spectrometry (single A4 without images or tables) can be submitted for inclusion in the forum page as individual fora to PeterBaugh682@hotmail.com or peter@analyticalmethodology.co.uk
Presentations in short PowerPoint format (< 5 Mb) or as pdf will be subsequently required for uploading to the documents page under the category Virtual EMS 2009 (or VEMS 2009 exhibition) for company manufacturer and service industry display uploads.
Please note that on application as a delegate, presenter or exhibitor you will be supplied with a user name and password to register and to enable you to log in for the VirtualEMS2009 conference. If you wish to register directly click on Register with Us in the LHS menu of the Home page at analyticalmethodology.co.uk and the documents page for viewing and uploading of presentations.
The conference is being organized by the Environmental Mass Spectrometry Special Interest Group (EMSSIG).

The Chromeleon 6.80 Extension Pack V2.0 which is free to Version 6.8 users — includes Sequence, Query, and Report templates that allow customers to quickly and easily perform and report common tests that can otherwise take a considerable amount of time.
With the Extension Pack, it is possible to calculate and report molecular weight averages and distribution in gel permeation chromatography (GPC)/size exclusion chromatography (SEC) directly in Chromeleon. EP and USP content uniformity testing has also been made easy. The templates calculate and report content uniformity results for up to three peaks and two experimental stages instantaneously. The evaluation of dissolution experiments for conventional release dosage forms according to EP and USP is complete in minutes with the new extension pack templates. Results for up to three peaks and three experimental stages are compared against specifications and presented graphically.

Modern HPLC Strategies: Improving Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Reliable Separation and Efficient Group-type Quantitation of Total Petroleum Hydrocarbons (TPHs)
September 11th 2024Petroleum contamination from leaking underground storage tanks, for example, is a significant concern for both the environment and human health. Thorough characterization of the contamination is required to form appropriate risk assessments and remediation strategies, but until now, the determination of total petroleum hydrocarbons (TPHs) in soil has typically involved a convoluted and labour-intensive process. In this article, the analysis of TPH in environmental media is simplified using flow-modulated GC×GC–FID with quantitation based on pre-defined compound groupings. This approach overcomes the drawbacks of conventional solvent fractionation approaches, by eliminating the need for sample fractionation and automating data processing workflows.
The Reality Behind Column Insertion Distance
September 10th 2024Column insertion distance is critical to good chromatography. What happens if the column is installed too low in the injection port? Is insertion distance more important when performing split injection or splitless injection? Does the position of the column in the injection port impact reproducibility?
