Beschreibung

General description

Purospher^® columns Si, 5 µm LiChroCART^™ 4-4 is a guard cartridge that allows the integration into a manuCART^™ cartridge column holder part number 1.51486.0001 for direct, dead volume free connection to an analytical LiChroCART^™ cartridge column with an inner dimension of 2, 3, 4, or 4.6 mm I.D. and a column length of 75, 100, 125, 150 or 250 mm.

For direct connection to Hibar^® RT columns, the Precolumn holder for 4-4 LiChroCART^™ cartridges, part number 1.51487.0001 can be used.

For connection to any other analytical HPLC column with capillary connection, the Precolumn holder for 4-4 LiChroCART^™ cartridges, part number 1.16217.0001 is suitable.

Application

Intended to be used for the separation of aflatoxins, carotenoids, oils, fat-soluble vitamins, lipids, and fatty acids.

Features and Benefits

• Ultra-pure silica (99.999%) for excellent peak symmetry
• High separation efficiency
• Reproducible results from run-to-run and batch-to-batch
• Use with Normal-phase or HILIC conditions (needs to be flushed to HILIC mobile phase)
• Good suitability for LC-MS applications
