Mark VI spray chamber for use with early model Agilent AA instruments.

• Simple-to-use twist and lock assembly makes for easy cleaning and routine maintenance
• Flexible operation with the capability to tune performance using the externally adjustable impact bead
• Fit mixing paddles for better precision and reduced burner blockage with the nitrous-oxide flame
• When fully optimized, it provides long operating times even when analyzing solutions with high levels of dissolved solids in a fuel-rich nitrous oxide-acetylene flame
• Can be adjusted for maximum sensitivity when analyzing solutions with low absorbance
• Inert construction makes spray chamber suitable for use with aqueous and organic solutions
• Fit organic resistant O-rings to ensure organic compatibility

The atomization system determines, the analytical performance of a flame AA spectrometer. The spray chamber promotes intimate mixing of 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.
