BWB Flame Photometers have always been renowned for a highly stable and accurate lithium measurement. This winning formula has been developed further with specific adaptation and optimization of the proprietary BWB optical array detection systems.
​
A well-earned thank you to Dr. Richard Roman of the University of Mississippi for his invaluable assistance on this Lithium specific FES.
​
The BWB Li uses multiple lithium detection channels. This latest configuration has been exclusively designed to specifications laid
out though consultation with our customers.
​
The BWB Li is the first of it’s kind. Engineered with a single purpose,
the BWB Li is the most accurate and advanced lithium flame photometer
(FES) ever manufactured!
