A method of forming a column ( 100 and 200 ) for use with an analytical chemical instrument. The method includes placing a frit ( 102 and 202 ) in proximity to a distal end ( 110 and 210 ) of a tube ( 104 and 204 ) having an internal bore ( 106 and 206 ) adapted to receive packing material ( 108 and 208 ) for selectively interacting with an analyte of interest in a sample. The method further includes laser welding the frit to the tube and inserting packing material within the internal bore of the tube. A column formed in accordance with this method.
