Purospher STAR RP-8 endcapped, 5µm, 120Å, 250mm x 4.6mmID, LiChroCART HPLC ColumnPurospher™ STAR RP-8 endcapped columns are suitable for a wide range of applications. As the sorbent is less hydrophobic than Purospher™ STAR RP-18 endcapped, analytes will typically elute faster on the C-8 phase. Hence, the column provides enhanced selectivity for positional isomers, and symmetrical peak shapes for strongly basic and less hydrophobic compounds.
ADVANTAGES Of Purospher™ STAR RP-8 endcapped HPLC columns
Excellent peak symmetry for acidic, basic and chelating compounds
Excellent resolution due to high separation efficiency
Excellent stability from pH 1.5 to 10.24NOTE - END FITTINGS:
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.
