Trajan CB Emitters. No clogs, just uptime

In proteomics and LC-MS workflows, even a small disruption can have a big impact. Emitter clogging, unstable spray, and inconsistent performance don’t just interrupt your runs, they reduce throughput, compromise data quality, and lead to costly reruns. Over time, this can significantly delay results and strain lab productivity.

Boost throughput, reduce downtime from emitter clogs

Trajan CB Emitters are engineered to address these challenges head-on. Unlike traditional pulled emitters, they feature a constant bore design, maintaining a uniform internal diameter all the way to the tip. This innovative approach dramatically reduces clogging risk and ensures consistent, reliable performance across extended LC-MS runs. 

Switching to Trajan CB Emitters delivers measurable improvements across your lab operations:

• Reduced downtime and reruns
  Constant bore design keeps instruments running longer and minimizes interruptions. 
• Enhanced sensitivity
  Precision-cleaved, zero dead volume (ZDV)-compatible ends paired with optimized tip geometry provides stable spray and improved peptide detection. 
• Accurate and precise quantification
  Consistent spray performance ensures reliable results across runs and between emitters. 
• High reliability and low variability
  Tight manufacturing tolerances guarantee reproducibility and reduce costly reruns. 
• Compatibility across sample types
  Chemically inert fused silica supports a all samples, including challenging phosphorylated compounds, without adsorption issues.

Three Coating Variants

Every lab setup is different, which is why Trajan CB Emitters are available in three coating options to suit your MS configuration:

• Uncoated (UC) - Ideal when voltage is applied at the liquid junction
• Gold Tip Coated (GTC) - Provides enhanced spray stability and sensitivity for non-FAIMS applications
• Gold Distal Coated (GDC) - Designed for FAIMS workflows, enabling improved positioning and efficiency

Each variant is available in multiple inner diameters (10 µm and 20 µm), giving you the flexibility to balance sensitivity and robustness for your specific application.
