Elements and isotopes

Overview

Elements and isotopes

Our researchers can help analyse your materials and samples using the cutting edge technologies in our elements and isotopes laboratory.

Our laboratory houses an array of top-end instruments for chemically analysing a wide range of gas, liquid and solid samples, down to parts per trillion in some cases. In the lab, researchers are able to analyse:

  • carbon, nitrogen and sulfur (CNS) content of various materials
  • methane, carbon dioxide and nitrous oxide concentrations in gases
  • elemental and isotopic composition of gases, liquids and solids.

Additional analytical chemistry equipment includes instruments for:

  • sample preparation
  • spectroscopy
  • mass spectrometry.

Most samples need to be crushed, powdered, extracted or diluted without process contamination into a form that can be analysed by the instrument. We can assist with preparing samples as required.

Research applications

  • Earth science - dating of mineral grains in rocks and sediments to determine the Earth's history
  • Environmental studies - measuring atmospheric greenhouse gases; analysing all elements from lithium to uranium, in a wide range of samples, such as soils, sewage sludge, additives in oil, cement, slag, and electronic components and parts; measuring compounds in liquid samples, such as river, lake, ocean, wastewater and industrial samples
  • Process engineering - quantifying target chemicals in a production line to meet strict standards

Typical projects

  • Dating minerals in sandstones to understand the ages and sources of sediments contributing to the sandstone
  • Measuring trace metals in soil and sediments to investigate how this affects ecosystems
  • Quantifying trace elements in vegetables and fruit flies and the relationship between them to aid in crop protection
  • Examining the effect of fertilisers on grassland
