6 Components of Sample Introduction Systems

• Peristaltic Pump or Syringe Drive

• Nebulizer

• Spray Chamber

• Torch

• Cones / Interface

• Tubing

Peristaltic Pumps / Syringe Drives • The method timings for uptake delay, stabilization delay, and rinse will depend on peristaltic pump and/or syringe drive performance

• Peristaltic Pumps

• More common, usually variable speed • Require Peristaltic Pump Tubing • Peristaltic Pumps can cause the sample flow rate to pulsate • Syringe Drives • Usually used with a peristaltic pump and switching valve • Push the sample at a more constant flow rate
