ARE UNMATCHED! The Techtron Premixed Burner-Atomizer Assembly is the most efficient and versatile available for atomic absorption and flame emission. It is designed inte grally from the bench up, and is not a compromise concoction of existing components. Audibility is com fortably low, with flame noise reduced to a minimum. Performance for all elements is maximized through simple, rapid interchangeability of burners that pro vide for the most efficient fuel and support gas mix tures. Burners available for AA: AB-40 AB-41 AB-42 AB-43 AB-44
Nitrous Oxide/Acetylene Air/Acetylene Air/Propane Air/Hydrogen Air/Acetylene (three-slot Boling type)
Also for Flame Emission: Techtron Flame Emission Burners are easily inter changeable with the AB Series, and used in conjunc tion with a simple chopper assembly, provide excel lent flame emission results. T h e complete burner assembly is readily adaptable for use on instruments of other major manufacturers.
