Abstract: A crescent PLOT column is disclosed, including a capillary column having an inlet, an outlet, a bore, and an inner surface surrounding the bore and extending between the inlet and the outlet. A layer of particles is localized on a radial portion of the inner surface. The layer of the particles includes a radial thickness decreasing from a center of the radial portion to a periphery of the radial portion, forming a crescent shape in a radial frame of reference. A method for preparing the crescent PLOT column is disclosed, including loading the capillary column with a fluid including a carrier and particles such that the fluid is contained within the capillary column. The capillary column and the fluid contained within the capillary column are subjected to a centrifugal force. The carrier is removed, and a layer of the particles is localized on the radial portion of the inner surface.

Abstract: A high aspect ratio vacuum air sampling assembly is disclosed including a first canister module. The canister module includes a high aspect ratio conduit having an aspect ratio of at least 30:1, an inlet disposed at an inlet end of the conduit, and an outlet with an outlet valve disposed at an outlet end of the conduit. The outlet is in fluid communication with the inlet through an internal volume of the conduit. An air sampling train is attached to and in fluid communication with the inlet, and includes an inlet valve, a precision orifice, and a flow controller. The inlet valve and the outlet valve are configured to isolate the internal volume of the conduit from fluid communication with an external environment when the inlet valve and the outlet valve are closed. The assembly may further include a second canister module or more in sequence.
