Summatic Integrator 1502
New UNISCAN® 900 TLC chromatogram scanning more accurate and convenient • Source and detector combined in a single monolithic unit • Source and detector move while sample surface stays stationary • Dual beam optics used in visible mode • Plug-in optical and electronic modules for single, double beam scanning, UV fluorescence and anti-log conversion • Interfaces with Model 1502 Summatic Digital Integrator and any recording or data logging equipment • Accommo dates TLC plates, paper and gel chromatograms and pho tographic films up to 8 χ 8".
• The Summatic Integrator is a new tool to automatically compute and present on printed tape, in digital form, peak areas which are a function of mass, concentration or struc ture. • Wide dynamic range 0 to 1 volt • Accuracy and precision exceed requirements for all analytical instruments • Full compliment of optional accessories including Base line Compensation, Time Printout, Log-Linear Adapter, and Tape Punch System • Unique peak detection system that provides for adjustable elimination of baseline noise without reducing slope sensitivity.
