HPLC guard column (analytical), NUCLEOCEL DELTA S, 5 æm, len

NUCLEOCEL DELTA Cellulose-modified silica phases for HPLC enantiomer separation Features Base material silica with chiral selector cellulose tris-(3,5-dimethylphenylcarbamate) USP L40 S versions with 5 μm particle size for higher resolution, allowing shorter columns (150 mm) for faster separations Pressure stability up to ~150 bar (2000 psi) Phases for normal phase applications Eluent in column n-heptane – propanol-2 (90:10, v/v) Typical eluents are heptane – propanol mixtures RP versions for reversed phase applications Eluent in column acetonitrile – water (40:60, v/v) Designed for use either in polar organic mode or with eluents containing high concentrations of chaotropic salts such as perchlorate Similar phases: Chiralcel® OD-H (normal phase, NP), Chiralcel® OD-RH (reversed phase, RP), Kromasil® CelluCoat™, Eurocel® 01, Lux™ Cellulose-1 Cellulose Recommended application: pharmaceutically active compounds, chiral pollutants (e.g., herbicides, PCB), chiral compounds in food (dyes, preservatives), chiral catalysts and bioorganic compounds
