Application Column

Newcrom B

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.

Select options
Application Analytes:
Benzoquinone
Chloranil
Chlorothalonil
Hydroquinone
Pentachlorophenol
Tetrachlorohydroquinone

Dewetting Study in Aqueous Conditions

September 18, 2003

Most reversed-phase HPLC columns, such as C18, are incompatible with 100% aqueous mobile phases due to dewetting (collapse) of the stationary phase. Primesep columns combine reversed-phase with polar functional groups which eliminate the problems of dewetting. The Primesep 100 column in this application with an acetonitrile (MeCN, ACN) shows a retention time of 2.5 minutes. In 100% water, the retention time is 3 minutes even after sitting 24 hours in the water mobile phase. On a C18 phase, the analyte retention would have been lost and elution at the void (1.5 minutes) would have resulted.

Condition

Column Primesep 100
Mobile Phase MeCN/H2O
Buffer No
Flow Rate 1.0 ml/min
Detection UV, 270 nm
