FARRAND announces the Spectrofluorometer that gives you all you will ever need • • • fully corrected • • • double - beam fluorescence Our basic Μ Κ 1 Spectrofluorometer can be pro vided w i t h any or all of the f o l l o w i n g modules — now, or as a future add-on:
CORRECTED EXCITATION - 200 to 700 nm using a spectrally flat thermopile CORRECTED EMISSION - 250 to 650 nm by means of a precalibrated f u n c t i o n generator DOUBLE-BEAM D I F F E R E N T I A L FLUORES CENCE ( A - B ) — useful over entire spectral range in corrected or uncorrected modes DOUBLE-BEAM ABSORPTION and DOUBLEBEAM RATIO FLUORESCENCE (A/B) available shortly This • • • •
unique instrument offers you: Sensible cost Simplicity of operation Corrected excitation down t o 200 nm Corrected emission to 900 nm w i t h a red sensitive photomultiplier tube • Long-term reliability • A system that does not require time consuming calibration
;·
Applications for this Double-Beam Spectrofluorometer are numerous: Elimination of Blank - permits the use of lower grade, less expensive solvents; eliminates Ra man peaks
Complex Biological Samples - time-consuming chemical separations and purification to elim inate background can be avoided Quality Control — samples can be compared di rectly w i t h a standard, for example, pharma ceuticals and drugs
FARRAND T H E FINEST IN
FLUORESCENCE FOR OVER 30 YEARS
Sample vs. Sample — similar samples can be compared to accentuate minor spectral dif ferences Matching Samples - for example, oil spills can be compared to various sources FARRAND OPTICAL CO., INC/COMMERCIAL PRODUCTS DIVISION Booths 134-136 at the Pittsburgh Conference CIRCLE 79 ON READER SERVICE CARD
