Precision, accuracy and robustness are key words and essential parameters to determine the effectiveness of any analytical application. Surveyors, refinery, and QC labs must determine the Nitrogen and Sulfur content with fewer personnel while the number of samples keep increasing and the time to report is under pressure. Moreover, all these analyses must be done in compliance with a variety of test methods, such as the ASTM D5453, ASTMD4629 and ASTM D6667. All these factors are pressing on...
Application of the Chemcatcher passive sampler for monitoring acidic herbicides in two UK river catchments
Acidic herbicides are used to control broad-leaved weeds. They are stable, water soluble, and with low binding to soil are found frequently in surface waters, often at concentrations above the EU Drinking Water Directive limit of 0.10 µg L−1. This presents a problem when such waters are abstracted for potable supplies. Understanding their sources, transport and fate in river catchments is important. We developed a new Chemcatcher® passive sampler, comprising a 3M Empore™ anion-exchange...
Taste and Odour challenges and the world's most sensitive detector
Improved GC/MS identification rates for untargeted waste water screening due to advanced deconvolution tools
For medium to complex matrices, it is well know that GC/MS deconvolution is probably one of the most important and critical steps to get reliable identifications for screening assays. The ultimate task is to obtain best estimated spectra for the pure components present in the sample. Besides deconvolution, the identification algorithm used to match unknown spectra with a spectral library also can have big impact on the final identification results, especially for components at low to very low...
Exploring the advantages of automated Sample Preparation and GC-TOF for SVOC & Pesticide Analysis in Environmental Waters
Recent advances in the sensitivity and selectivity and modern GC-MS instrumentation combined with the development of laboratory robotic systems have made it possible to miniaturise and automate traditional sample preparation methods without compromising compound limits of detection. In particular the application of fully automated Dispersive Liquid/Liquid Microextraction (DLLME) shows great promise for the extraction of a very wide range of organic pollutants from aqueous matrices. Combinatio...
Implementation of the Medium Combustion Plant Directive and Specified Generator regulations, the monitoring requirements and how they will be regulated
Presented at AQE 2018 Conference in Telford. Implementation of the Medium Combustion Plant Directive and Specified Generator regulations, the monitoring requirements and how they will be regulated.
Extraction of hydrocarbons within shale oil and gas formations present different technical and environmental challenges when compared to extraction from conventional hydrocarbons formations. The main concern is related to the use of hydraulic fracturing processes to break apart the rock and release the hydrocarbons. One of the primary environmental issues in relation to this process is the underground water supplies which can become contaminated by chemicals used in the fracking process as we...
Nitrogen and phosphorus are essential elements for humans as well as flora and fauna. In addition to their role as a nutrient their presence can also give important information about a sample e.g. the practice of over-fertilization or the likelihood of heavy metals being present in water bound to phosphate. Consequently, the determination of these elements is indispensable for the evaluation of water quality. The analysis of Total Nitrogen (TN) and Total Phosphorus (TP) to estimate such ri...
Ion selective field effect transistors: highly versatile tools for accurate detection of ions in water - WWEM 2018
Presented at WWEM 2018. Nowadays, the tight environmental regulations demand a close control of the water quality in rivers, sea or even in waste waters. The water quality control require a regular monitoring due to continuous changes in several key parameters, such as seasonal water chemistry, overgrowing of plants, industrial waste and other factors. The chemical, physical and biological properties of the water define its quality. Currently, monitoring analytical parameters like the pH, te...
