A recently granted patent (Publication Number: US11819786B2) discloses a novel column design featuring a filter device with multiple components. The filter device includes a first filter, a second filter with a smaller pore size, retaining members for each filter, and a hollow ring-shaped member placed between the filters to maintain a non-contact state. The column body is filled with a filler to separate components in a filtered sample. A cap is mounted to the column body to secure the filter structure in place, ensuring efficient filtration.

Additionally, the patent claims detail specific features of the filter device, such as a ring-shaped contact portion within the hollow ring-shaped member, the thickness of the spacer relative to the pore size of the first filter, and the materials used for the filters and retaining members. The patent also mentions the inclusion of a third filter with a larger pore size upstream of the first retaining member, providing further filtration capabilities. These innovative design elements aim to enhance the efficiency and effectiveness of the filtration process, making it a significant development in the field of column technology.
