Cole-Parmer Cyano Guard Cartridges, 5 µm, 10 mm L x 2.1 mm ID; 4/PK

The cyano columns are less retentive than C18 and C8 in reverse-phase applications. Applications include the retention and separation of strongly basic analytes and fast elution of hydrophobic molecules. Use in normal phase systems to retain and separate polar analyte compounds. It is ideal for the separation of aromatic alcohols, pesticides, and broad ranges of pharmaceuticals, including steroids and analgesics.

Columns come in 316L stainless steel (SS) tubing hardware. A SS female end fitting with a SS and PEEK frit system keeps the stationary phase in place and packed bed from disturbance. The SS end fitting accepts a male 10-32 threaded nut with standard 1/16" OD tubing.

Use the guard cartridges to maintain chromatographic integrity. They ensure erroneous materials are kept out of the more important and expensive analytical columns, leading to more accurate results. Simply match the sizes to select the correct guard cartridge for your column; guard cartridge holder 16470-89 is required to use the guard cartridges. In-line filters are available for your UPHLC and HPLC columns—order separately.
