Acquisition of automated peripherals for the Stable Isotope Laboratory, University of New Mexico

该提案的资金将用于升级该部的稳定同位素实验室。地球和行星科学，新墨西哥州大学。 为了增加通量并最大限度地增加用户数量，我们将购买用于沃茨、碳酸盐和顶空气体的自动进样器（CombiPAL自动进样器）和自动连续流接口（Finnigan GasBench II）。 自动进样器将允许我们测量顶空气体（d15N），大气蒸汽（？D）、碳酸盐（d13C？18O）和沃茨（？18O）在非工作时间自动运行。 升级的第二部分是在我们的质谱仪上安装一个差分泵装置，以便？17O测量可以在连续流动条件下进行。 当全面实施时，我们应该能够对陨石进行现场测量，这是我们与UNM陨石研究所合作的一部分。

EAR-0233689SharpFunding from this proposal will be used to upgrade the stable isotope laboratory in the Dept. of Earth and Planetary Sciences, University of New Mexico. In order to increase the throughput, and maximize the number of users, we will purchase an automated autosampler for waters, carbonates and head-space gases (a CombiPAL autosampler) and an automated continuous flow interface (Finnigan GasBench II). The autosampler will allow us to measure head-space gas (d15N), atmospheric vapor (?D), carbonates (d13C & ?18O) and waters (?18O) automatically during off-hours. A second part of the upgrade is to install a differential pumping unit on our mass spectrometer so that ?17O measurements can be made in continuous flow conditions. When fully implemented, we should be able to make in situ measurements of meteorites as part of our collaboration with the Institute of Meteoritics, UNM.***
