Trajan CB Emitters

Boost throughput – reduce downtime from emitter clogs

In proteomics labs, every minute of instrument downtime slows results and reduces throughput.  That’s why Trajan CB Emitters are engineered to resist clogs, reduce downtime, and keep LC-MS workflows running without interruption.

Unlike pulled emitters, Trajan CB Emitters feature a constant bore design that maintains a uniform internal diameter (ID) to the tip – reducing clog risk and delivering consistent performance across extended runs.

Key Benefits

• Reduce downtime and sample reruns
  Constant bore design resists clogging – reducing downtime and reruns while boosting sample throughput.
• Achieve high sensitivity
  Precision-cleaved, zero dead volume (ZDV)-compatible ends paired with optimized tip geometry – delivers high sensitivity and deep proteome coverage.
• Ensure accurate and precise quantification
  Optimized tip geometry delivers efficient, stable spray for enhanced peptide detection and reproducible performance across runs.
• Achieve high reliability through low variability
  Tight manufacturing tolerances and rigorous quality control ensures emitter-to-emitter reproducibility – reducing the need for reruns after emitter changes.
• Run any sample
  Chemically inert fused silica supports all sample types – including phosphorylated samples – avoiding adsorption associated with stainless steel

 

Three coating variants for MS source compatibility

Trajan CB Emitters are manufactured in-house to ensure consistent quality and process control. They are available in three coating options to suit a
range of MS source configurations, and each variant comes in 10 µm and 20 µm inner diameters – giving scientists flexibility to balance sensitivity and
robustness for their workflow.

 

Uncoated (UC)
For source configurations where voltage is applied at the liquid junction rather than the emitter, these emitters deliver reliable performance without the need for a conductive coating.

Gold Tip Coated (GTC)
For source configurations where voltage is applied directly to the emitter body through its conductive coating, these emitters deliver enhanced spray stability
and efficiency – providing greater sensitivity and reproducibility in non-FAIMS applications.

Gold Distal Coated (GDC)                                                                                                                                                                                                                                                                                                                                      Ideal for FAIMS configurations, these emitters feature a non-conductive tip that eliminates arcing associated with stainless steel. This allows the emitter to be
positioned closer to the source, improving spray efficiency and stability.
