"First published in Water Science the newsletter of the RSC Water Science Forum"


The WSF was delighted to support this event with awards for the best student oral presentation, best student poster and best runner up student poster.

The winner of the best oral presentation was Cornelius Brombach from the University of Aberdeen who present his research “New Speciation Method for Mercury in Water and Biological Samples by Selective Pre-concentration and Subsequent Analysis via HPLC-CV-AFS”.

After receiving the award Cornelius said:

"My research wouldn't be possible without the support of my supervisors W.T. Corns, B. Chen, E. Krupp and J. Feldmann. A special "Thank you" to them. I want to say a huge "Thank you" to the WSF of the Royal Society of Chemistry for donating the award. Winning the award is a nice acknowledgement of my research and I am grateful for it".

LN061201 - PR - Mercury in the Petrochemical Industry - Applications for Liquefied Natural Gas (LNG)

For many years P S Analytical has been at the forefront of developments relating to the measurement of mercury in the Petrochemical Industry.

P S Analytical's measurement systems are based on the PSA 10.525 Sir Galahad atomic fluorescence instrument. The Sir Galahad is a very flexible system, and using a combination of hardware and software, the PSA Research and Development team have been able to configure the Sir Galahad to accommodate a wide range of sample types. Natural Gas and Syn Gas (containing high levels of hydrogen sulphide) have been regularly measured in both online and offline applications. Recently we have worked with a commercial company to provide a unique measurement system for liquefied natural gas. A fully automated system for the application has been operational for a number of years providing vitl data to control the function of the plant. The Sir Galahad was developed with the Petrochemical industry in mind. Initially working with the Institute Français du Petrold (IFP) methods were developed to provide reliable measurements in natural gas streams. P S Analytical and the IFP have been providing analytical expertise in this area since that time. (See more...)
