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

Alterate selectivity for increased MS/MS identification of peptides and sequence coverages.
