Maximize reproducibility with tight-tolerance fused-silica and smooth surface finishes
After a long process of modelling and experimenting, Trajan managed to develop their new robust nESI-emitters. Trajan tapered nanospray emitters are designed for those seeking maximum reproducibility, reliability, and sensitivity in their ESI-MS workflows. Available in a wide range of lengths, inner diameters, and coating options make Trajan’s tapered emitters suitable for most source configurations.
Features & Benefits:
- Manufactured in certified ISO 9001 environment to ensure premium quality and assurance of supply.
- Constant inner diameter, with tapered outer diameter for added robustness and reduced propensity to clogging.
- Ultra-fine tip geometry for greater ionization efficiencies.
- Precision cleaved for low dead volume connections.
- Customization available with integrated PEEK sleeve to promote easier installation and more reliable connections.
- Available in various IDs, ODs, and lengths to suit a variety of MS sources and platforms.
- Uncoated, tip-coated, and distal-coated emitter configurations available to accommodate various source configurations and voltage application methods.
