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...

A fast and reliable characterisation of biodegradable organic matter (BOM) is essential to ensure efficient pollution removal by wastewater treatment plants (WWTP) along with a necessary reduction of the environmental footprint resulting from treatment process operation (energy and raw material consumption, greenhouse gas emission). Biochemical Oxygen Demand (BOD) is a worldwide used indicator for assessing the BOM content of wastewater. The BOD measurement rests on a 100 years old analytical...

Whatever your requirement is with regards to monitoring your water data it is undoubtedly true to say the quicker that you receive the data back the more efficient and effective you can be at responding to it in the right location. With potentially vast pipework networks in place its often the case that you can only react when there is already an issue, not proactively to prevent potentially unacceptable levels of change. The movement of the 'Internet of Things' seeks to change this by mon...

Engineered silver nanomaterials (AgNM) have become an essential part of our daily life. Being used as antibacterial mean in numerous products such as e.g., deodorants, cleaners or sportswear, AgNM finally end up in the environment, where their behavior and fate is still widely unexplored mainly due to the lack of available analytical techniques and methodologies for their determination at trace levels in complex matrices. In this presentation, the hyphenation of Asymmetrical Flow Field-Flo...

Traditionally, water chemistry has been measured by taking spot samples, either manually or using autosamplers, transporting to a laboratory where the samples are then analysed. In situ analysis removes the logistical problem of transporting samples, meaning larger data sets can be obtained. The quality of data can be higher by removing the risk of sample deterioration or contamination. Furthermore, it raises the possibility of large scale networks of sensors deployed on moorings and auton...

Affinity Water's 36 Ml/d output karstic groundwater site in Hertfordshire abstracts from four boreholes which are then blended and treated at the works. All four sources contain metaldehyde, some at a constant low level and others at highly variable and rapidly changing concentrations. Affinity Water and Anatune Ltd have developed an application of an Agilent Technologies Triple Quadrupole GCMS instrument with GERSTEL automated sample preparation and sampling to take quasi real-time sample...

The UKAS perspective including special reference to the SCA Inorganics and Metals working group

This presentation will aim to summarise the recent work carried out across three distinct working groups covering the organics subcommittee as well as the ad hoc groups responsible for production of guidance documents on both sample stability and uncertainty of measurement estimations for regulatory drinking water analysis. The work of the organics subcommittee has been at the core of SCA since its inception in 1972 and it's fair to say that the technological advances made in this area in...
