Abstract: Dimethylmercury permeation devices are described, as well as methods of forming the devices and methods of utilizing the devices, e.g., in calibration of an analysis device. The permeation devices are loaded with methylmercury and formic acid that react to form pure phase dimethylmercury in a supersaturated solution. The dimethylmercury will equilibrate at an equilibrium vapor pressure in the headspace and diffuse at a temperature controllable rate out of the permeation device for use.

Abstract: Sampling devices for sampling an aqueous source (e.g., field testing of ground water) for multiple different analytes are described. Devices include a solid phase extraction component for retention of a wide variety of targeted analytes. Devices include analyte derivatization capability for improved extraction of targeted analytes. Thus, a single device can be utilized to examine a sample source for a wide variety of analytes. Devices also include an isotope dilution capability that can prevent error introduction to the sample analysis and can correct for sample loss and degradation from the point of sampling until analysis as well as correction for incomplete or poor derivatization reactions. The devices can be field-deployable and rechargeable.

Abstract: A first pair of semicylindrical frame basket retainers are hingedly affixed to a horizontal platform in spaced relation and open in opposite directions. A linking device is mounted on the platform between the first pair of basket retainers and is pivotally coupled to each of the retainers at distances above the platform for rotating the retainers about their hinges under the control of a user. A latch device mounted on the platform between the first pair of retainers releasably secures the retainers in positions of inclination relative to the platform. A second pair of semicylindrical frame basket retainers are affixed to the platform in a manner whereby the first basket retainers and second basket retainers are paired to form a pair of cylindrical trash can retainers, each pair of trash can retainers having a basket retainer of the first pair and a basket retainer of the second pair.
