Column Assembly

How does it work?

  • SIELC provides an end-piece (A), which includes a 150-mm long narrow bore
    PEEK capillary with permanently installed stainless steel sleeve
    and with 0.05-mm thick SS frit.
  • Assembly (B) includes a connection of the end-piece (A) with empty PEEK capillary column and
    compressing the sleeve by our specialized tool (D).
  • The axial forces produced by the tool compresses the end of the sleeve within the anvil
    to form a tight permanent connection of the sleeve to the column body (C).
  • Fully assembled ready for packing capilary column is also available from SIELC
