LC-MS: 4-Methylmidazole in Cola and Instant Coffee
LC-MS: Methylmidazole isomers
LC-MS: Sulfonic acids and sulfuric acids
Sodium alkyl sulfates (SAS)
LC-MS: Perfluoroalkyl acids (PFAA)
LC-MS: Ionic Lquid (1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide)
The Scherzo SM-C18 and Unison UK-Amino columns successfully separate the small, polar ascorbic acid related compounds in normal phase mode.
The Unison UK-Phenyl column separates surfactants of different lengths better than a standard C18 column.
The Scherzo SW-C18 column is able to retain compounds with multiple amine functionalities.
The Scherzo SM-C18 and SS-C18 show excellent resolution of these small molecules, which normally coelute on a standard C18 column.
Both Presto FF-C18 and Intrada WP-RP can elute this large protein. Intrada WP-RP shows sharper peaks, meaning it can better recognize its structural components than Presto FF-C18.
LC-MS analysis of phosphorus-containing amino acid type herbicides and their metabolites
Aromatic carboxylic acids
Levulinic Acid, Lactic Acid and methyl Esters
Malachite Green and Metabolite
PEG can be separated by both reversed phase and normal phase chromatography. Reversed phase using the Cadenza CW-C18 column gives baseline resolution as well as better run time.
The Cadenza CW-C18 column effectively separates triarylmethane ink dyes because of chelating properties.
Positional Isomers on CL-C18
Separation Properties of Polycyclic Aromatic Compounds on CL-C18
The reverse phase separation of the hydrophillic organic solvent dimethyl sulfoxide (DMSO) is difficult. However, our silica columns make a nonaqueous normal phase separation possible.
