A superb optical system combines tradition and modern production techniques.

A highly stable and sensitive double beam system with 8 μΙ quartz flow cells and a detection capability between 0.001 and 2 A.U. permits the selection of precise wavelengths re­ quired to match the absorption characteristics of compounds separated by high or low pressure liquid chromatography. With the Schoeffel SPECTROFLOW SF 770 a band of fre­ quency between 200 and 630 ηπ\ at full sensitivity and without photodecomposition can be obtained. Accurate analyses at absorption maxima are now quickly possible. Limitation to work on or near absorption minima or on the shoulder of a spectral emission line or to detect via the intervening step of derivatization has been eliminated. Send today for com­ plete technical literature.

SCHOEFFEL A pleasure to use. Designed specifically for the chemical m i c r o s c o p i s t , m i n e r a l o g i s t a n d petrologist.
