2012 Student Awards and SIMSUG
This week I'll be attending the Stable Isotope Mass Spectrometry User Group (SIMSUG) meeting at Lancaster University:
SIMSUG 2011, Lancaster University, 23rd and 24th November 2011
To coincide with the meeting we are announcing our 2012 Student Research Awards competition. Hopefully, I will get to meet some of our customers in Lancaster but you don't have to be at the meeting to enter the competition as the details are below.
The closing date for entries is 31st January 2012. Good luck to everyone that applies.

Student Placements During the Summer
This June we welcomed one of our customers to the lab to gain first hand experience of stable isotope analysis. Dr Irene Maier recently took up a post doctoral position in the Quaternary Geology and Climate unit of the Norwegian Geological Survey (NGU), Trondheim. Under the direction of Dr Jochen Knies, Irene is being supported by an EU Marie Curie award to work on their Changing Arctic and Sub-Arctic project.
During her visit to the laboratory Irene gained practical experience of preparing marine sediments for carbon and nitrogen isotope analysis. This involved; decarbonating the sediments in preparation for organic carbon isotope analysis, removal of organic nitrogen from the sediments and preparation of the different sediment fractions for analysis on the mass spectrometer systems. By doing this, Irene now has an understanding of the processes involved in stable isotope analysis which should come in useful when she receives data for future samples that we will be measuring for NGU.

In July we were joined by a second student for a summer placement. This time it was Charlotte who had just completed the first year of her degree course in environmental sciences at Manchester University. Charlotte spent a couple of weeks with us gaining practical experience of common laboratory techniques which included; centrifuging, pipetting, ion-exchange chromatography and using 5 place balances to weigh and prepare samples in tin capsules ready for isotope analysis.

The Lab continues to be very busy
It was around this time last year that we started to see an increase in the demand for analysis of samples. That demand has remained in place and I can safely say that our lab has never been busier. This is good news and not so good news. Good news because it is very encouraging to see that so many of you are increasing the amount of research that you are using stable isotopes for. The not so good news is that the increased number of samples that we have been receiving has meant that the lead time for analysis has increased for most sample types.
In order to meet the increased demand, we did two things in the first quarter of this year. First off, we re-furbished and upgraded one of the mass spectrometers that was under-utilized. This has given us extra capacity for high temperature continuous flow - IRMS and extra capacity for deuterium measurements. Secondly, we recruited another person for the technical support staff, Joanna Bruce. Joanna has already been trained up to prepare samples and is now doing so on a day to day basis alongside the rest of the team (Anne, Margaret and Sharon).
Even with this extra capacity in place the lead times for analysis are still longer than they used to be and what we would like them to be. We apologize to you for that but would also like to thank all of our customers for your patience. All samples that arrive at our facility are logged in, in the order that they are received and join the queue behind orders that have already arrived. We think and hope that this is the fairest way for all of our customers.
It is good to know that people are willing to wait a bit longer because of the quality of the service that we provide.

Row for Heroes
On Wednesday 12th May 2010, two Army Doctors, Nick Dennison and Hamish Reid, set out to Row around Great Britain in order to raise money for Help for Heroes and the Army Benevolent Fund. In doing so they will enter the record books by being the first pair to complete this Herculean task.
The charity rowers wanted to monitor their energy expenditure during the challenge. So we at Iso-Analytical volunteered to help out by providing them with a doubly labelled water kit which they could use during the trip. The kit consisted of doubly labelled water drinks, collection containers for urine samples and everything needed to keep records of the sampling times:
On their return we will measure the two sets of urine samples that they will have collected from two study periods. Measuring the differential loss of deuterium from the body (only lost as water) and oxygen-18 (lost as water and carbon dioxide) allows us to calculate their total energy expenditure over study periods as long as two weeks. We're expecting Nick and Hamish's energy expenditures to be somewhat higher than normal!
To find out more about the challenge, track their progress and the charity they are supporting, please visit their website: Row for Heroes

Iso-Analytical Student Award Provides a First for Deuterium Analysis
Unravelling complexities in benthic food webs using a dual stable isotope (hydrogen and carbon) approach.
Peter Deines, Matthew J. Wooller and Jonathan Grey, Freshwater Biology (2009) 54, 2243-2251.
In the journal article above the authors provide preliminary evidence to suggest that hydrogen and carbon isotope values in macroinvertebrates may be used to distinguish between methane formation pathways and help to explain inter-depth and inter-specific differences between co-existing chironomid species found in the same lake.
Peter Deines of the Max Planck Institute for Limnology, Plon, Germany used his Iso-Analytical Student award to send samples to our laboratory for analysis. Samples of chironomid larvae collected from German lakes were measured for their deuterium abundance. As far as the authors are aware this is the first study to use deuterium as a second biochemical marker in combination with carbon-13 (measured in their own laboratory), to unravel linkages between microbial fauna in sediment and macroinvertebrate consumers.
