LiChrospher® 100 NH2 LiChroCART®
Inner Diameter (I.D.): 4 mm
Length: 250 mm
Package Contents: 1 Cartridge
LiChrospher® 100 NH2 provides polar and hydrophobic properties and can be used for normal phase chromatography,
reversed-phase chromatography and ion exchange chromatography. Typical applications are the separation of
carbohydrates (mono-, di- and oligosaccharides) with reversed phase chromatography or the separation of nucleotides
with LiChrospher® NH2 as weak anion exchanger.
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.
