Need Different Wavelengths, Spectral Scans, Peak Ratios? The New EM SCIENCE/Hitachi* Model L-3000 Multi-Channel Photodiode Detector is capable of all these functions. ' P 1$S9&lw3iiK95flgBwnni wmflftftorThe maximum absorption of all samples. SPECTRAL SCANS — determine the absorp tion spectrum of each peak for identification. PEAK RATIOS — for the determination of peak purity, ratio two different wavelengths as a single output. The L-3000 Multi-Channel Photodiode Detector will function as a free-standing detector or in concert with other EM SCIENCE/Hitachi HPLC modules. For additional information on the L-3000 or to arrange for a demonstration, call or write: To c o m p l e t e your m o d u l a r E M S C I E N C E / H i t a c h i H P L C S y s t e m s , request additional information o n : • Pumps • U V Detectors • Semi-Micro Systems
