Chemical analysis of soils and associated materials

The Data Science Revolution Data comes from many sources: from the results of water analysis to the time, date and location of a customer complaint. The ability to turn data into information is determined by: the skill of wrangling data (also making sure the data is in an appropriate electronic format that can be used in the first place!) checking the data is not random and maximising its value; and delivering the findings in a format that is accessible and can be clearly underst...

Increasingly stringent legislation in the European Union has driven down SO2 emissions on many processes from the 100's mg.m-3 to the 10's mg.m-3, or in some cases even lower. Consequently, the measurement challenge to accredited providers of compliance measurements and EN 14181 QAL2 calibrations has become increasingly difficult, and meeting legislative uncertainty requirements far from a trivial matter. We take stock of current capability for measuring this important pollutant and present s...

Regulatory update on the Industrial Emissions Directive, including the Best Available Techniques Reference document (BREF) for Large Combustion Plant, and also the requirements of the Medium Combustion Plant Directive.

This eLearning session is for anyone analyzing residual solvents or interested in quantitative GC-Headspace analyses.         GC-Headspace is a powerful technique for the analysis of volatile compounds in neat samples or in a variety of matrices. A major use of GC-Headspace is the analysis of pharmaceutical drugs, as well as intermediates and excipients for the presence of residual solvents that may be left over from the manufacturing process. The sample that is analyzed by this t...

We present a detailed description and experimental results for a new gas emission survey method that remotely detects and maps the locations of multiple gas emission sources distributed across an extensive area. Our method, which we call LightSource, not only localizes but also estimates the mass emission rates of each of the detected sources. The approach is generally applicable to any airborne contaminant that is passively transported and conserved during transport within the area of intere...

Tunable diode laser spectroscopy (TDLS) is an important measurement technology for gas detection, offering both high sensitivity and specificity to the target gas. With this technique, much of the engineering requirement and achievable field performance is attributable to the gas cell in which the light interacts with the target gas. We present two new technologies for gas cells, each with different attributes, used for methane detection in different applications.  The first technology ha...

Laser Dispersion Spectroscopy (LDS), is a new gas sensing technique that applies a novel approach to tuneable diode laser spectroscopy. Established laser absorption techniques depend on measuring detected intensity to derive concentration. This significantly impacts measurements in "dirty" environments where detected intensity of the transmitted light is bound to fluctuate. MIRICO's LDS-based instrument derives concentration using the phase of light. This makes it highly immune to intensity f...

In 2014 the US Department of Energy's ARPA-E program initiated MONITOR, a 45M US$ investment in methane detection technologies. The eleven technologies funded under the program are reaching the end of their second development year and beginning field testing. Initial testing has been performed at the Methane Emissions Test and Evaluation Center (METEC) at Colorado State University, which reproduces emissions behavior at oil & gas (O&G) wells, small compressor stations, and underground gas gat...
