A system for analysis of H<sub>2</sub> and Ne in polar ice core samples
Abstrak
<p>This paper describes instrumentation and procedures developed to measure H<span class="inline-formula"><sub>2</sub></span> and Ne in polar ice core samples. Gases are extracted from ice core samples by melting under vacuum. Measurements are conducted by gas chromatographic separation with detection by a pulsed helium ionization detector (He-PDD). The analytical system was developed for field analysis of ice core samples immediately after drilling. This minimizes the potential for exchange of these highly permeable gases between the ice core and the modern atmosphere. The design, operation, and performance of the instrument are discussed using data from the initial deployment to Summit, Greenland. The results demonstrate the feasibility of ice core analysis of H<span class="inline-formula"><sub>2</sub></span> and Ne with precision of 8.6 % and 10.2 % (1<span class="inline-formula"><i>σ</i></span>) respectively.</p>
