Microcomputer controlled chemical and radiochemical separations and analysis

Creator:

Bennett, Casey Wayne

Abstract:

An automated radiochemical flow analysis (ARFA) system was developed which integrates chemical and radiochemical techniques into one system through the use of a microcomputer. The operator, through the microcomputer, controls valves and pumps to transfer sample and reagent solutions to counting loops, ion exchange columns and holdup reservoirs. A Ge(Li)...

Development of trace enrichment techniques for trace metals in natural waters using high pressure liquid chromatography

Creator:

Ambrose, Arthur Sigurd

Abstract:

An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...

Design, construction and application of an instrument for simultaneous measurement of molecular fluorescence, absorbance and chemiluminescence

Creator:

Yappert, Marta Cecilia

Abstract:

An instrument was constructed to measure molecular fluorescence (FL) or chemiluminescence (CL) and absorbance (ABS) simultaneously. The lower, middle, and upper portions of the test solution are probed to obtain ABS, FL, and CL data. Optical fibers are used extensively. The ABS and FL or CL spectra are acquired in...
