Examples of popular phases: |
|
|
|
Monitor C18 is a top-quality phase,
providing excellent stability and reproducibility, and minimal
secondary interaction. Monitor is a perfect choice for reversed
phase separations requiring thoroughly base-deactivated
columns, and excels in challenging pharmaceutical and peptide
separations. |
Manufacturer: Column Engineering, Inc.
Particle Size: 3µm, 5µm
Pore Size: 100 Å
Carbon Loading: 17.5%
Surface Area: 350 m2/gram
pH Range: 1 - 9.5
Advantages:
-Improved peak shape for basic and acidic compounds
-Very reproducible results
-Low back pressure for longer column life |
|
KROMASIL C18 |
|
Kromasil C18 is a popular material
for pharmaceutical/bioscience applications. Kromasil offers
excellent chemical and mechanical stability. |
Manufacturer: Eka Nobel
Particle Size: 3µm, 5µm
Pore Size: 100 Å
Carbon Loading: 17.5%
Surface Area: 300 m2/gram
pH Range: 2 - 9.0
Advantages:
-Low back pressure
-Cost-effective for scale-up
-Good peak symmetry for basic compounds |
|
RELIASIL C18 |
|
Reliasil is an oligomerically derivatized silica gel. It
is preferred by many chromatographers for its chemical stability
and effectiveness in the reversed phase separation of peptides,
pharmaceuticals and derivatized amino acids. |
