Columns and cartridges for gas, ion, HPLC, low-pressure LC, and flash chromatography; includes pre-packed and open columns, packing, guard columns and accessories, and other supplies for flash chromatography.
Astec™ CYCLOBOND™ I 2000 RSP chiral HPLC column is basically comprised of native and derivatized β and γ cyclodextrins. It has been used for numerous chiral separations via selectively trapping the organic molecules in the cyclodextrin cavity.
No. 15 Ace-Thred at top and 2 mm bore, solid-PTFE stopcock-plug (tapered 1:5) at bottom. Supplied with nylon and FETFE™ O-ring for connecting 12.5 to 14 mm O.D. tube to column, and with tubing connector.
Use a glass column for applications where high inertness is required, such as for the analysis of active analytes. All glass columns undergo a proprietary high temperature silanization to ensure inertness.
The LC-CN phase is often used as a substitute for silica because it offers the advantages of a bonded phase (such as quick equilibration, and less sensitivity to small changes of the water content in the mobile phase).
