BackgroundAt the present time, optimization of dietary and fitness practices are inadequately addressed in the clinical setting, and poorly documented through research studies investigating response to surrogate disease markers. Identifying and quant

Emerging chemical threats to homeland security challenge the specificity of sensor-based chemical detectors. As the number of chemicals to detect increases, the false alarm rates of these sensor-based systems tend to increase and the usefulness of th

We have designed and tested a spectral infrared emissivity device (SIRED) for studying the FT-IR emission spectra of solid surfaces. The cell, which is commercially available, can be used from near room temperature to 400°C. Emissivity results obtai

The feasibility ofusing JR mapping microspectroscopy to locate and identify a neuroanatomicalprobe in brain tissue has been demonstrated. Frequency specific IR maps were generated from a latexnanosphere injection site in brain tissue. The 2240 cm1 vC

A novel geometry for internal reflection elements is described. These elements have been found most useful in the FT-IR analysis of samples by attenuated total reflectance (ATR). Both single and multiple internal reflection elements are described. Th

An instrument is described for the rapid mixing of solutions. Gas presure, controlled by electronically operated solenoid valves, is used to eject solutions from microsyringes into a stirred solution. It can be used to initiate and quench enzymatic r

This paper reports on the first spectra obtained using a microscope apparatus to perform FT-Raman spectroscopy. It is considered desirable to use a standard FT-IR microscope for these measurements, since this approach may lead to the attainment of bo

The Kubelka-Munk relationship is the equation most commonly used to describe the reflectance from a scattering medium. This equation breaks down, however, in several important situations in the mid-infrared. Most notably, the relationship does not ac

The practice of microspectroscopic analysis now spans the complete optical spectrum. The most recently popular of these measurements is the mid-infrared region where transmission, specular reflection and diffuse reflection measurements are performed

Diffuse reflectance has become one of the simplest technics available to the researcher for the FT-IR analysis of powdered samples with a minimum of sample preparation. However, it is still not used widely as a quantitative tool. Papers have appeared
