Abstract
The disclosure describes methods and devices with which to process and analyze difficult chemical, biological, environmental samples including but not limited to those containing bulk solids or particulates. The disclosure includes a cartridge which contains a separation tube as well as one or more valves and cavities for receiving raw sample materials and for directing and containing various fluids or samples. The cartridge may contain a separation fluid or density medium of defined density, and structures which direct particulates toward defined regions of the cartridge. Embodiments can include a rotational device for rotating the cartridge at defined rotational rates for defined time intervals. Embodiments allowing multiple assays from a single sample are also disclosed. In some embodiments, this device is used for direct processing and chemical analysis of food, soil, blood, stool, motor oil, semen, and other samples of interest.
