Abstract
A filter insert, a sample vial incorporating a filter insert, a method of using a sample vial containing a filter insert for chemical analysis, and a sample vial kit including a filter insert. The filter insert includes a cylindrical body having a proximal end, a protrusion extending radially from the proximal end of the cylindrical body and configured to set on the open end of a sample vial, a distal end, a cavity extending longitudinally through the cylindrical body from the proximal end to the distal end, and a filter assembly coupled with the distal end of the cylindrical body.

A sample filter kit, the kit comprising:
- a cylindrical filter body comprising:
- a proximal end,
- a protrusion extending radially from the proximal end of the cylindrical filter body and configured to set on a proximal open end of a sample vial,
- a distal end,
- a cavity extending longitudinally through the cylindrical filter body from the proximal end to the distal end, and
- a protrusion extending from an internal surface of the cylindrical filter body adjacent the distal end toward a center of the cylindrical filter body;
- and
- a plurality of filter assemblies, each of the plurality of filter assembly assemblies comprising:
- a cylindrical ring having an external surface with a recess extending from the external surface into the cylindrical ring, and
- a filter insert disposed within the cylindrical ring adjacent the recess, wherein
- engagement of the protrusion and a recess of one of the plurality of filter assemblies couples the cylindrical filter body with the one of the plurality of filter assemblies.
A sample filter kit, the kit comprising:
- a cylindrical filter body comprising:
- a proximal end,
