Introduction
Dennis C. Krueger is an accomplished inventor based in Richmond, TX (US). He has made significant contributions to the field of environmental monitoring and fluid sampling. With a total of 2 patents, his work focuses on enhancing the accuracy and efficiency of dosimetry and sampling devices.
Latest Patents
One of his latest inventions is the "Thermally Desorbable Passive Dosimeter." This device features a structurally reinforced sorbent wafer designed to monitor a worker's exposure to ambient aromatics such as benzene, toluene, ethylbenzene, and xylenes. The wafer is created by pressing 4 mg of sorbent material between two pieces of 100 mesh stainless steel wire gauze, resulting in a thickness of about 1 mm. This innovative design significantly reduces background noise during gas chromatographic analysis, allowing for the detection of lower concentrations of air contaminants compared to other passive dosimeters.
Another notable patent is the "Negative Pressure Gas Sampling Device." This apparatus is designed for collecting fluid samples and includes a sealable container with an opening and cover. It features an inlet that communicates with the environment outside the container and a sample vessel that can be filled and sealed when samples are drawn. The device allows for selective evacuation and pressurization, enabling the vessel to alternate between filling with fluid and emptying its contents.
