Surface characterization of ceramic materials. [LEED, AES, XPS, ion scattering spectroscopy, secondary ion mass spectroscopy]

Description: In recent years several techniques have become available to characterize the structure and chemical composition of surfaces of ceramic materials. These techniques utilize electron scattering and scattering of ions from surfaces. Low-energy electron diffraction is used to determine the surface structure, Auger electron spectroscopy and other techniques of electron spectroscopy (ultraviolet and photoelectron spectroscopies) are employed to determine the composition of the surface. In addition the… more

NH/sub 3/ preconcentrator/integrator instruction manual. [Measured 10 parts per billion of ammonia in room air]

Description: Microwave rotational spectrometry is a very selective analytical technique for polar gaseous compounds. For some selected molecules (e.g., HN/sub 3/, H/sub 2/CO, SO/sub 2/, etc.) concentrations as low as 100 ppB can be detected by continuously flowing the analyzed gas mixture through the absorption cell. However, some form of preconcentration of the desired species is required for detection limits below 100 ppB. Initial work with various trap materials for ammonia suggests using chromatographic… more

Rapid analysis of hay attributes using NIRS. Final report, Task II alfalfa supply system

Description: This final report provides technical information on the development of a near infrared reflectance spectroscopy (NIRS) system for the analysis of alfalfa hay. The purpose of the system is to provide consistent quality for processing alfalfa stems for fuel and alfalfa leaf meal products for livestock feed. Project tasks were to: (1) develop an NIRS driven analytical system for analysis of alfalfa hay and processed alfalfa products; (2) assist in hiring a qualified NIRS technician and recommend c… more

Selective spectroscopic methods for water analysis

Description: This dissertation explores in large part the development of a few types of spectroscopic methods in the analysis of water. Methods for the determination of some of the most important properties of water like pH, metal ion content, and chemical oxygen demand are investigated in detail. This report contains a general introduction to the subject and the conclusions. Four chapters and an appendix have been processed separately. They are: chromogenic and fluorogenic crown ether compounds for the sel… more
