Columns with a new outer design and with a new chemistry inside.
Available diameters: 2.1, 3.2, and 4.6 mm.
Available length: 50, 100, and 150 mm.
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:
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.
