Impact Beads for Atomic Absorption Spray Chambers
The atomization system determines the analytical performance of a flame AA spectrometer. The spray chamber promotes intimate mixing of the nebulized aerosol with fuel. Proper spray chamber design ensures minimal carbon build-up, plus reduced burner blockage and volatilization interferences.
The Agilent flame AA spray chamber has an adjustable glass bead positioned in front of the nebulizer venturi, which breaks up the aerosol droplets and provides the operator with control over the aerosol concentration. Removable twin-head mixing paddles twice reverse the direction of aerosol rotation, promoting further mixing and large droplet removal. This ensures a fine aerosol, which reduces burner blockage and noise, and improves long-term signal stability..

Product Details
Features
- Impact beads are compatible with the current Mark 7 and earlier Mark V and Mark VI atomization systems used with Agilent flame AA instruments
- Adjusting the impact bead position during optimization of the flame AA provides control over sensitivity, noise, interference effects, calibration linearity and working range, and potential for burner blockage
- Optional inert PTFE bead available for use with samples that have high concentrations of dissolved solids, or hydrofluoric acid which can etch or chemically attack the standard glass impact bead
