Abstract: A gas and vapor analyzer system and method of detecting a gas or vapor sample are provided. An FTIR spectroscopy system of an analyzer system comprises an interferometer adapted to modulate an excitation signal. A gas cell is adapted to receive the modulated excitation signal and focus the modulated excitation signal within the gas cell via an input lens. An off-axis multiple reflection geometry is adapted to receive the focused modulated excitation signal and pass the focused modulated excitation signal through a gas or vapor phase specimen via a plurality of beam paths skewed relative to a longitudinal axis of the cell to generate an optical sample signal. An exit lens is adapted to direct the optical sample signal from the gas cell to an IR radiation detector, and a controller is adapted to identify a detected gas and vapor sample based on the optical sample signal.

Abstract: A device and method for preparing a sample for solid-liquid or liquid-liquid extraction are provided. In one embodiment, a device includes a sealed container including an opening for receiving a solid sample and a reservoir. The reservoir includes a solvent or is adapted to receive a solvent. The solid sample and the solvent are mixed in the reservoir and to concentrate at least one component of the sample into the solvent within the reservoir. The concentrate is settled into a solvent layer within the container. The solvent layer is sampled via a port. A method includes introducing a solid sample to a solvent; creating a solution by mixing the solid sample with the solvent; allowing the solvent solution to settle into at least one layer; and sampling within at least one layer.

Abstract: A method for determining an amount of polar substance in a non-polar media includes adding a surfactant to increase a dispersion of the polar substance in the non-polar media and to increase the optical absorbance of the polar substance in the non-polar media to create a sample, passing an initial optical spectrum through the sample, measuring a resultant optical spectrum exiting the sample, relating the resultant optical spectrum to a predetermined quantitative calibration, and determining a concentration of the polar substance in the non-polar media based on the relation of the resultant optical spectrum to the quantitative calibration.
