Radial Flow Gas Chromatography

这个探索性项目将建立和测试一个径向流色谱仪，并展示这种新技术的可行性。将建造一个薄饼状的床，直径3英寸，厚度约为1/2英寸。床将填充300目活性氧化铝微粒，在5000 psi压力下压实。床层的色谱响应（在吸附质脉冲的冲击下）将与轴流柱的色谱响应进行比较。这些数据将用于判断大径向流色谱仪的可行性，如果是肯定的，则用于判断大径向流色谱仪的性能。这一创新可能导致(1)紧凑型手持式色谱仪的实际发展，以及(2)用于工业应用的高性能，小尺寸（因此节省了吸附剂和设备成本）色谱仪。

This exploratory project will undertake to build and test a radial flow chromatograph, and to show the feasibility of this new technique. A pancake-shaped bed, 3-inch diameter and approximately 1/2-inch thick, will be constructed. The bed will be packed with 300 mesh fine particles of activated alumina compacted under 5000 psi pressure. The chromatographic response from the bed (upon the challenge of a pulse of adsorbate) will be compared with that from an axial flow column. These data will be used to judge the feasibility and, if positive, the performance of large radial flow chromatograph. This innovation could lead to the practical development of (1) compact hand-held chromatograph, and (2) high-performance, small-size (hence savings in sorbent and equipment cost) chromatograph for industrial applications.
