PFASs (per- and polyfluorinated alkyl substances) are a class of almost 10.000 organofluorines. These man-made compounds - also designated «forever chemicals» – are highly persistent and at least some of them tend to accumulate and biomagnify in the environment. For that reason, more and more of these compounds are declared toxic as they pose a risk to human and environmental health. In a joint eLearning session, Theresa Steurer and Iris Reber from Metrohm International Headquarters,...

In this eLearning session we describe the specific gravity measurement in the whole refining process- from upstream to downstream. We introduce the theoretical background to the technique, the advantages of digital measurement over traditional approaches and introduce the broad equipment solutions from Anton Paar. We place a particular focus on the practical aspect of this parameter in the daily routine to ensure full compliance with ASTM D4052, D5002, D7777, D8188 & ISO 12185. Our densi...

Gas chromatography (GC) is one of the most important analytical technologies, but its power relies on the availability of sensitive detectors, able to quantify a range of analytes as extensive as possible. This webinar will show the Pulsed Discharge Detector (PDD) to meet this demand by combining true universality in detection, with a broad dynamic range, and sensitivity down to the ppm and ppb range. After setting the PDD in relation to other detectors for GC, generally regarded as univer...

This eLearning demonstrates how to consolidate routine analysis of multiple parameters on a modular platform. Increasing numbers of samples, multiple parameters to be determined, mandatory compliance with national and international standards – water works, bottlers of mineral water and some sectors of the process industry all face the same challenge: How to cope with more analytical tasks while human resources in the laboratory are limited? In this eLearning session we demonstrate how...

Biofuels, mainly derived from vegetable oils or the fermentation of plant material, have gained importance over the last few decades as more sustainable and environmentally friendly alternatives to fossil fuels. However, the production of raw materials for biofuel production has led to significant deforestation and competition for agricultural farmland with traditional crops used as staple food for humans and animals. To mitigate effects, new sources like algae have been developed for biofuel...

At our recent Air Quality and Emissions event, Dr. Lesley Sloss of the International Centre for Sustainable Carbon gave a 20-minute presentation outlining emerging approaches to the global challenge of monitoring mercuring. Dr. Sloss addresses: The global spread of mercury pollution Contemporary and historical regulation of mercury emissions Alternatives to direct, fleet-based monitoring Cutting-edge modelling software for the estimation of emissions

At our recent Air Quality and Emissions event, David Graham of Uniper gave a 30-minute presentation outlining current standards for the quality assurance of mercury around the globe. Mr. Graham discusses: The similarities and differences between quality assurance procedures in the United States and Europe Type-testing requirements and measurement uncertainty Alternatives to current conventions in performing linear calibration The most effective methods for performing certifi...

At our recent Air Quality and Emissions event, Dr. Johannes Pfingsten of VDZ gave a 10-minute presentation comparing methods for the monitoring of mercury emissions. Dr. Pfingsten discusses: The advantages and disadvantages of the prevailing reference method, EN13211 Different methods for reducing the limit of quantification Prospects for the wider utilisation of sorbent-trap methods Controlling breakthrough at different concentrations

At our recent Air Quality and Emissions event, Shawn Wood of Ohio Lumex gave a 20-minute presentation comparing methods for the monitoring of mercury emissions. Mr. Wood considers: The prospects of emerging sorbet-trap technologies A range of reliable means for cement and power plants to achieve compliance The state of plant regulation in the United States Notable emissions limits for power and cement plants

Crude oils contain as many as 45 elements, many of which can have adverse effects on petroleum refining and product quality. These effects can include poisoning of the catalysts used during the refining process or corrosion to the process equipment. The determination and quantification of these trace elements can be particularly challenging because of the high viscosity of many crudes and the presence of large particulates. This requires time-consuming sample preparation, such as ashing and w...
