Abstract: A UV absorption spectrometer includes a housing, a controller, and a sensor unit including an ultraviolet light source, an analytical area in an analytical cell or in running water or gaseous medium, and an UV wavelength separator including a UV detector. An ultraviolet light in a wavelength range of 200-320 nm emits from the light source through the analytical area to the wavelength separator, and the controller transforms output signals from the UV detector into absorbance values or optical densities for two or more wavelengths in the wavelength range, calculates differences of said absorbance values or optical densities, determines a concentration of a chemical in the solution with calibration constants found for a known concentration of the chemical and said differences of said absorbance values or optical densities.

Abstract: A container for holding a sample and a system and method for a handheld spectrometer using the container is disclosed. In one embodiment, the container includes a vial with an optical window at the base of the vial. A sample may be placed in the vial. A hollow plunger may be slidably inserted into the vial which seals the gap between the plunger and the walls of the vial. The plunger includes a filter element. When the plunger is inserted into the vial, the sample is forced against the optical window and the filter element vents liquid and/or gas that is in the vial into the hollow plunger. A portable or handheld system for detecting, for example, biothreat agents makes use of the container in order to determine a spectrum of the sample. The optical window of the container is preferably substantially transparent to photons illuminating the sample and to photons produced due to the interaction of the illuminating photons and the sample.
