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.

共享的质谱仪具有支持生物学创新研究，环境和地质研究的复合能力：稳定的同位素研究与环境研究具有较大的相关性，其中许多研究构成了理解澳大利亚陆地和海洋系统的主干。比通过大量方法获得的化合物特异性同位素分析所产生的信息要多得多。问题是分离是劳动密集型和使用复杂的湿化学。新方法减少了足够的负载，以使化合物特异性研究成为可能。在碳同位素的情况下，新的液态色谱技术消除了对稀释自然信号的衍生作用的需求，并且可能使其无法使用。
