The need to look beyond the conventional target pollutants when assessing the hazards of chemicals to human health and to ecosystems is now generally recognised as a priority issue in all environmental policy areas at both the European level and national level in the various countries. All EU Member States are struggling now to develop the...
This talk will summarise many of the successful projects carried out in Anatune's application laboratories over the last year or so, with an empahsis on the automation of sample preparation and injection. Applications to be discussed include:
The automated analysis of metaldehyde in water (both in the lab and in the field)
Fully...
Is there still room in the chromatography laboratory for selective detectors, or is mass spectrometry the only way to go?
This paper explores the current state of the art of the XSD and PFPD selective detectors and their applications in the laboratory for consumer products, food and petrochemical samples.
In 2009, Jones Environmental became the first UK laboratory accredited to perform soil gas analysis using passivated canisters. The instrumentation employed for this task (the Entech 7150 Preconcentrator), has many unique characteristics - not least the ability to acheive very low limits of detection. This new capability enables us to perform a...
Due to its high toxicity and as a tell-tale sign of industrial activity, cyanide analysis is routinely performed in many analytical labs, including environmental laboratories on both water and soil samples. Due to the complexity of cyanide chemistry, it is both a challenging analysis that can lend itself to interferences and a time consuming...
GC-Olfactometry (GC-O) is a valuable method for the selection of odor components from a complex mixture. In particular, GC-O in combination with MS (GC-O/MS) allows not only evaluation of the odor compounds, but also identification with mass spectral information. However, many key odor compounds can occur at very low concentrations. Therefore,...
Gel Permeation Chromatography (or Size Exclusion Chromatography) has been around for several decades, and is used routinely for polymer analysis and for sample cleanup. In this application development, citrus based essential oils are cleaned up by GPC prior to pesticide residue analysis in order to get rid of the main matrix. The results prove...
The rapid, accurate and reproducible analysis of developing products in support of performance enhancements is a key aspect in delivering new and/or improved technologies to our customers. The presentation will discuss how the GERSTEL Headspace/MPS2/SPME system interfaced to an Agilent GCMS was developed to enable these demands to be met for a...
Alcoholic beverages and especially distilled spirits represent a relatively clean matrix and it is possible to avoid costly sample preparation by proper choice of suitable GC sample introduction techniques.
The sample introduction technique can be selected to match the volatility of the target analytes. Sample introduction techniques in...
