Pulse Damper

Pulse Damper
  • A system for accurate and stable analysis with elimination of pulsating flow of the pump from liquid chromatograph and FIA.
  • Inner capacity of the damper is designed in small size for ease of exchanging reagent.

Damper Use Sample

Pulsating flow is radically reduced down to 1/50 with the use of the damper.

  • Pump used : uf-7002SZ (Single Plunger Pump)
  • Damper used : PD0235P
  • Flow rate : 400μl/min
  • Ave. Pressure : 0.5MPa
  • Chart speed : 15mm/min
