For as long as people have done HPLC they have used the same column format, the same method of attaching the column to the HPLC, and they have  experienced the same problems:

  • Clogging at the tube-column junction
  • Leakage around the high pressure solvent connections
  • Installation problems with tubing to achieve zero dead volume
  • Selecting the proper tube length and ID
  • Sorting through many available high pressure fittings


To address these issues  a new column design was developed. This column and corresponding adapter entirely eliminate the need
for any high-pressure fittings or tubing as well as minimizing all possible dead volumes. Furthermore, if a leak ever occurs in the high-pressure column inlet, the mobile phase is contained within the column adapter (no external leakage).
You need to install a column adapter once on your HPLC. Then without any tools you can install a column which never leaks, it is easy to replace and can be changed in seconds.  The column hardware was  designed specifically to be used in any HPLC instrument. It can be installed in most column heaters as well.
