PARTICLE SAMPLE PREPARATION WITH FILTRATION

A liquid transfer line receives a liquid having particles suspended therein and transfers the liquid to a capillary tube. A support tube secures the capillary tube therein. The support tube is substantially airtight except at a designated position. An optional securement secures the capillary tube within the support tube. A discharge end of the capillary tube is spaced from, and receded into, a discharge end of the support tube. A chuck is positioned below the support tube and is operable to open and to close to seal the designated position of the support tube. A sample substrate filters the liquid introduced through the liquid transfer line. Yet further, the sample preparation system comprises a pump that draws a vacuum that exhausts portions of the liquid that are not retained on the sample substrate.
