A quadratic programming routine for the statistical analysis of gas chromatographic data

Creator:: Elliott, Stanley Claud, Jr
Abstract:: A quadratic programming method was developed for the statistical analysis of gas chromatographic data. The method was applied to three types of flavor extracts, peppermint, hops and brewed tea. The brewed tea data had to be abandoned because of the singularity of its coveriance matrix. In all cases tried the...

Theoretical and experimental factors affecting the accuracy and precision of atomic absorption measurements

Creator:: Bower, Nathan Wayne
Abstract:: A procedure for evaluating the precision of atomic absorption measurements is presented and applied to 21 elements under varying instrumental conditions. The experimental relative standard deviations (RSD's) in absorbance obtained from repetitive measurements made with a high resolution voltmeter and on-line computer, are compared to those predicted by a recently...

Design of a chemiluminescence photometer and its application to trace chromium (III) analysis

Creator:: Hoyt, Steven D.
Abstract:: The design and construction of a chemiluminescence photometer is described. The design is based on a discrete sample system which has a number of advantages over the previously described flow cell system and centrifugal analyzer. The advantages include simple and inexpensive equipment, small sample size, versatile electronic readout system, and...

A study of simultaneous diffusion of Ca²⁺ and Sr²⁺ in alkali chlorides

Creator:: Machida, Hisashi
Abstract:: The simultaneous diffusion of Ca 2+ and Sr 2+ ions in purified single crystals of KC1 and NaC1 was studied over the temperature ranges from 451°C to 669°C in KC1 and from 448°C to 683°C in NaCl. A radioactive tracer technique was used in two types of measurements: diffusion from...

Design, development and optimization of a fluorometric reaction-rate instrument and method of analysis for metal ions

Creator:: Wilson, Robert Loren
Abstract:: The design, construction and operation of a fluorometric reaction rate instrument is described. The instrument is designed for simple operation with maximum versatility. Advantages and modes of operation of the system are discussed in detail. The instrument is used for the kinetics-based determination of trace levels of Ag and Al....

A chemical study of the minerals from L-6 chondritic meteorites

Creator:: Curtis, David Ballantyne
Abstract:: Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

Variations in trace element abundances in small fragments from a single terrestrial basaltic flow : applications to 59 Apollo-17 mare basaltic fragments

Creator:: Rivera, Maria Rita Dacanay
Abstract:: Eleven hand specimen whole rock (WR) samples (25-200 g each) and 33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture Gorge, Oregon were analyzed via instrumental neutron activation analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb, Lu, Hf and Ta). Standard...
