The invention provides a cuvette apparatus having two cavities that are in fluid communication with each other. The first cavity is larger than the second cavity an receives a fluid to be studied. The second cavity holds the fluid for analysis and is bounded by at least two thin walled windows that allow superior transmission of UV waves.

A system and method for detecting a substance using x-ray fluorescence is disclosed. The detected substances may be explosives or controlled substances that have a specific chemical fluorescent signature. An energy source transmits an x-ray beam at a target. The target may be in a container or under a surface. The beam interacts with the target to produce fluorescent energy. An x-ray detector is at an angle relative to the energy source and gathers the fluorescent energy. The angle differs according to the physical configuration of the system. A portable embodiment will have a different angle than a stationary embodiment. A cooling mechanism cools the x-ray detector. The fluorescent energy is analyzed and processed by a multichannel analyzer and a computer. The computer determines whether the fluorescent energy from the target matches known fluorescent energies of specific substances. If the substance is detected, appropriate indications are made to prevent damage or acceptance of the substance.
