IntegraFrit™ Columns

Reduce tailing and achieve maximum sensitivity

Like PicoFrit^® columns, IntegraFrit™ columns are fabricated from 360 µm OD, polyimide-coated, fused-silica tubing, but without a tip. The frit end of the fused-silica column has been polished flat to ensure a clean connection to your emitter of choice. Each IntegraFrit column has an integral high-porosity frit, behind which is the packed chromatography bed. The frit virtually eliminates tailing caused by other extra-column frits.

  

• Compatible with ESI-MS and MALDI
• Biomolecule and MS-compatible
• Frit is free of adhesives, binders, and polymers
• Frit adds very little back pressure
• Packed with any of our high-performance chemistries or SCX material
• Short columns (1 or 5 cm x 75 µm) for sample trapping and desalting procedures
• Long columns (10 cm x 75 µm) for nanobore LC
• Custom packing is available for other column IDs (50, 100, 150 µm) or user-supplied materials
