LiChrospher® 100 DIOL LiChroCART®

Inner Diameter (I.D.): 4 mm
Length: 250 mm
Package Contents: 10 Pieces
 
 
LiChrospher® 100 DIOL provides both polar and hydrophobic properties, thus can be used as a less polar alternative 
to LiChrospher® Si 60 in normal phase applications or as a less hydrophobic alternative with some limitations to 
LiChrospher® RP-8 in reversed-phase applications. The combination of weak hydrophobic interactions and polar 
interactions enables successful separations of complex samples. In addition, LiChrospher® DIOL is also suitable for 
exclusion chromatography.
 
With LiChroCART® cartridges the user works with re-usable endfittings which fit different cartridge lengths. 
Since these cartridge holders may remain in the system and the capillary connections do not need to be detached, 
the cartridges may be changed within the shortest possible time. Changing a separation cartridge from a length 
of 125 to 250 mm and back presents no problems. Furthermore, the adaptation of internal diameter (3 mm or 2 mm) 
to the analysis problem is possible within a few minutes. The endfittings are designed to allow the cartridges to be 
hand-sealed at normal working pressures of 150 to 200 bar without the need for any tools. Only at higher pressures 
may further tightening with a wrench become necessary.
