A shared mass spectrometer with compound-specific capabilities to support innovative research in biology, the environment and geology: Stable isotope studies have huge and increasing relevance to environmental studies, many of which form the backbone of understanding Australia's terrestrial and marine systems. Compound-specific isotope analysis yields much more information than is available through bulk methods. The problem has been that the separations were labour-intensive and employed complex wet chemistry. New methods reduce the work-load enough to make compound-specific studies possible. In the case of carbon isotopes, new liquid chromatographic technology removes the need for derivatisations which dilute the natural signal and can render it unusable.

具有特定化合物功能的共享质谱仪，可支持生物学、环境和地质学方面的创新研究：稳定同位素研究与环境研究有着巨大且日益密切的相关性，其中许多研究构成了了解澳大利亚陆地和海洋系统的支柱。化合物特异性同位素分析产生的信息比通过批量方法获得的信息多得多。问题在于分离是劳动密集型的并且采用复杂的湿化学。新方法减少了工作量，足以使特定化合物的研究成为可能。就碳同位素而言，新的液相色谱技术消除了衍生化的需要，衍生化会稀释自然信号并使其无法使用。
