Abstract: In at least one embodiment, the inventive technology relates to in-vessel generation of a material from a solution of interest as part of a processing and/or analysis operation. Preferred embodiments of the in-vessel material generation (e.g., in-vessel solid material generation) include precipitation; in certain embodiments, analysis and/or processing of the solution of interest may include dissolution of the material, perhaps as part of a successive dissolution protocol using solvents of increasing ability to dissolve. Applications include, but are by no means limited to estimation of a coking onset and solution (e.g., oil) fractionating.

Abstract: At least one embodiment of the inventive technology relates to a frozen environmental sample temperature control system that comprises a frozen formulation having water in an amount from substantially 87% to 78% by weight of the formulation, and salt in an amount from substantially 13% to 22% by weight of the formulation, the system further including at least one container containing the frozen formulation; and a cooler having insulating material disposed between an outer wall and an inner surface that defines an inner chamber into which the at least one container and the at least one frozen environmental sample may be placed for storage and/or transport. Various embodiments may incorporate specific types of insulating material and/or adaptations to an inner surface of the cooler to enhance the insulation effected thereby.

Abstract: A soil sampling system is provided that allows headspace screening of soil samples at spaced intervals along a soil sample liner without disturbing the soil samples to be collected and shipped to a laboratory for further testing. The soil sample liner includes a plurality of cylindrical liner sections positioned end-to-end in a linear array, with each liner section having a sidewall and open ends. A shrink-wrap material covers the liner sections and holds the liner sections together as an assembled unit. Some of the liner sections have access openings formed in a sidewall thereof for providing access to the soil samples contained therein. The liner sections having access openings are interspersed between other liner sections that do not have access openings. The access openings are used by piercing the shrink-wrap material covering the access opening, and inserting a probe tip through the access opening into a headspace to measure contamination.
