There is nothing like the
MicroSolv Cogent Diamond
Hydride™ HPLC columns
for LC-MS and HPLC. Made
from TYPE-C™ silica, they
are the perfect choice for very polar and many nonpolar compounds.
Used with MS-friendly mobile phases, these columns
are routinely employed for metabolites, bioanalysis, and other
compounds. Different from HILIC columns, TYPE-C phases
have a slightly hydrophobic surface without a water layer.
Therefore they equilibrate rapidly, even after gradient runs, and
offer fantastic precision and robustness. www.mtc-usa.com
