Trace element variation during magmetic differentiation of tholeiitic rock sample from Tasmania - chlorine and fluorine in hydroxyl lattice sites
Organic cyanine dye for detection of protein in trace amounts - dye reaction mechanism, methods of eliminating inorganic compound reaction with dye, and detection of humic acid
Sorbent material and platinum and palladium catalyst testing for development of Apollo spacecraft trace contaminant removal system
Methods for separating inorganic compounds from organic materials in investigation of trace proteins in soils
Properly programmed combination of advanced chemical and physical analytical techniques characterize critically all trace contaminants in both the potable and waste water from the Apollo Command Module. This methodology can also be applied to the investigation of the source of water pollution.
Trace amounts of hydrazines in aqueous solutions can be determined by using polythyleneimine /PEI/ in conjunction with the gas chromatographic column. The PEI specifically retains water without altering the separability or elution order of the hydrazine and associated constituents.
Trace contaminant identification using microwave double resonance spectroscopy
Trace elements in sporulation of bacteria and germination of bacterial spores
Diffusion of Freon and helium trace gases for detection of leaks in aerospace systems
Mass spectrometric method for rapid identification of trace volatile metabolites of respiratory atmosphere contained in isolated incubation flask
Ray tracing in ionosphere, calculating position coordinates and time delay for plane stratified plasma
Method for isolating metal ion traces from sodium matrices consists of two extractions and an ion exchange step. Extraction is accomplished by using 2-thenoyltrifluoracetone and dithizone followed by cation exchange.
Special analytical column having in series two separate absorption sections charged with beads of porous polymer and a sample of gas detects traces of hydrocarbons. New method requires only 15 minutes for execution.
Computerized optical system ray tracing study for solar simulator optimization through defocusing
Development and design of isotope heated catalytic oxidizer trace contaminant control system
High frequency radio wave propagation research using Alouette 2 topside sounder data and digital ray tracing techniques
Techniques for use in mass spectrometry of gaseous trace contaminants
Hydrothermal investigation of Ge trace quantity distribution between metal, silicate and sulfide phases at controlled oxygen partial pressure by oxygen buffer techniques
