IntegraFrit™ Sample Trap Inserts by New Objective

Description

Optimized for Proteomics
IntegraFrit Sample Traps combined with Upchurch Scientific® Fittings are a perfect combination for concentrating and separating samples for mass spectrometry. Integrated with a titanium frit, the key to the sample trap is the 360 µm OD fused-silica tubing packed with one of our outstanding chemistries.

• Trap column IDs of 75 µm, 100 µm, and 150 µm
• Place in injection loop for sample prep
• Use as nanobore guard column
• Column length of 2.5 cm
• Ideal for rapid sample analysis
• Combine with an ultra-low volume (<2 nL) IntegraFrit as an outlet frit
• Custom packing for other column IDs or user-supplied materials

Sample Trap Efficiency

Matching trap and analytical column sorbents result in improved peak resolution, higher overall loading capacity, and improved pep-tide recovery.

A 300 fmol BSA digest sample was prepared and run using two separate sample trap/column configurations:

-Right, top - Run using an IntegraFrit sample trap and a PicoFrit analytical column both packed with ProteoPep II C18 5 µm 300 Åchemistry.

-Right, bottom - Run using an IntegraFrit sample trap and a PicoFrit analytical column each packed with different chemistries.

Robust and Reliable

Like our PicoFrit and IntegraFrit columns, IntegraFrit sample trap columns are fabricated from 360 µm OD, polyimide-coated, fused-silica tubing. The ends of the precision cut 2.5 cm column of the fused-silica column is polished flat to ensure a clean connection.The chromatography bed is packed behind the frit.
