Don't turn your back on Flame Photometry! UNTIL YOU TRY UNICAM If you think that Flame analysis is too limiting for your work, reserve judgment until you see the new Unicam SP-900 Flame Spectrophotometer. The Unicam is not an "attachment" or compromise instrument, but a complete Spectrophotometer, d e signed specifically for emission work. Now you can consider flame analysis for elements other than the Alkali Earth Metals. Manganese, Copper, Boron, Magnesium, Silver and many others are being done routinely on the SP-900. Unicam's unique burner and atomizer design, coupled with superior electronics, gives stability and repro ducibility never before seen with a flame instrument. Permits use of new addition and buffer techniques for the elimination of mutual interferences.

The SP-900 has other noteworthy features. Standard readout is with a spot galvanometer and the addition of any 10 mv external recorder makes the SP-900 a full recording flame spectrophotometer. So don't sacrifice the inherent speed and accuracy that is possible with flame photometry until you try the Unicam SP-900. Write today for the Unicam SP-900 Bulletin and to arrange a demonstration of this startling new instru ment.
