and physiology to aquaculture, marine spatial planning and conservation.

Elemental analysis

To determine the quantity of compounds and elements within an organism or environmental sample, we have a wide range of analytical equipment. 

Elemental analysis is used to determine the percent composition of each element present in an organic chemical compound, typically carbon, hydrogen and nitrogen. A small sample of compound is burned in a pure oxygen atmosphere, and the amount of carbon dioxide and water that is formed determines the percent composition of carbon and hydrogen is the sample.

We also have a facility for atomic absorption spectroscopy (AAS), a common technique used in many analytical chemistry protocols, as well as applications requiring a high degree of precision and accuracy,  including environmental sampling. Atomic absorption spectrometers may be used to analyze the concentration of over 70 different elements in a given sample solution. 

Our viscometer has mainly been used to measure the viscocity of oils, important contaminents of the marine environment. It also has the capacity to measure flow behaviours of other fluids. 

We have a range of spectrophotometers, measuring transmittance and/or reflectance of UV/UVF and Infra-red in samples.
