SSI Binary Gradient Pump Modular Simplicity
Ideal Gradient Characteristics Modular design Small foot print Easy Maintenance Compatible with stand alone control & Data systems 1 l to 5ml/min flow range with 1% resolution
Integrated Binary Gradient Pump Small footprint Integrates fluidics Simple control Low dead volume High precision
Easy Maintenance Modular design Simple seal changes Self flush is standard Pumps are on pull out drawers Each pump is independently serviceable
Fluid Path Fully Accessible Easy Set up –Connect inlet lines –Connect line to Injector –Prime pump 200 l Delay Ez Prime in head PPV
Simple Front Panel Control Can select and set –Flow –Max pressure limit –Low pressure limit Allows monitoring –Pressure –Flow Start or stop the pump
EZ Prime Allows each head to be primed independently Can prime head while other pump is running
High Performance Dead volume is minimized 0.001ml/min flow resolution Out gassing effects minimized since mixing is on high pressure side of pump Precise digital control of each solvents flow Use data system interface for control or keypad controller
Low Delay Volume 200 l Delay Flow 0.5ml/min step at 3.0 min
Millivolts Minutes 2% Gradient Steps at 0-10%
Millivolts Minutes Fast Gradients at 3 mL/min 100%A for 2 minutes 0-100%B in 1 min, 3 min
Linear and Step Binary Gradient Profile, 250 L/min; Two Runs Superimposed 100%A for 2 min; 0-100%B over 25 min. Gradient Accuracy was determined to be 1% absolute (of set value)
Easy System Configuration Add a detector Choose a manual injection valve or Autosampler Choose a column Choose your data collection system Begin
Wide Variety of Controllable Detectors FluorescenceUV/Vis –Single Channel –Multi Channel –Diode Array Conductivity Evaporative Light Scattering
Works With All Analog Detectors Use EZ Chrom SI with 35900E A to D box Use a keypad controller and a strip chart recorder
