About Us
Oxy-Anion Stable Isotope Consortium (OASIC) was established by Prof. Huiming Bao in
2001 at 海角社区 (U.S.A). OASIC鈥檚 research and educational activities
are relevant to energy, environment, and human well-being. OASIC is now offering high-quality
stable isotope ratio measurement services to the greater research, government, and
industrial communities.
Research
A common thread of our research has been the use of high-dimensional stable isotope systems to "read" geological, biological, and environmental records, with a special interest in the history of our evolving atmosphere.
The tools that we use include gas-source isotopic ratio mass spectrometry (dual-inlet
and conflo), laser-fluorination systems, vacuum lines, GC, IC, ICP-ES, SEM, XRD, and
wet- and photo-chemistry lab facilities. OASIC has built up a unique stable isotope
laboratory that is specialized in the isotope-ratio measurements of most elements
in water-soluble oxy-anions such as sulfate, nitrate, perchlorate, phosphate, and
hydroxide. OASIC is capable of chemical preparation and measurement of 未D, 未15N, 未18翱,&苍产蝉辫;未17翱,&苍产蝉辫;未34厂,&苍产蝉辫;未33S, and 未36S values of SO42-, NO3-, ClO4-, and PO43-with the best precisions in the community.
