1-2 Overview
Waters Prep series
The Waters Prep Series offers these features:
• Two pump configurations:
–150-mL
flow rate with 500-µL pump heads at 4000 psi
–300-mL flow rate with 1000-µL pump heads at 2000 psi
Tip: Fitted with 1000-
μ
L pump heads, the PrepLC or Delta-Prep system
can operate at twice the flow rate of a 500-
μ
L pump head system,
permitting separation of larger sample loads.
• Four-solvent gradient capability (Auto
•Blend™ method)
• Pump purge valve to facilitate priming and purging of solvent lines
• Plunger wash with integral pumping system
• Single keypad control of PowerLine™ system and/or gradient conditions
• Ability to configure the system to recall certain default conditions
• Methods storage that lets you access previously created gradient, event,
and detector tables
• Preprogrammed gradient profiles
• System control of external PowerLine detectors and autoinjectors is
through an IEEE-488 interface
• RS-232 serial communications interface for connecting to an optional
data workstation or integrator
• Shelf unit to house system modules in an integrated assembly that
optimizes the volume of interconnecting tubing
PrepLC system
The PrepLC system performs both analytical and preparative scale
chromatography. Use its pump with either 500- or 1000-µL volume heads. The
500-µL pump heads allow flow rates of 1 to 150 mL/min and the 1000-µL
heads a rate of 4 to 300 mL/min.
The PrepLC system uses 0.040-inch ID tubing, which accommodates large-
and small-scale operation. To optimize system performance, you can change
critical tubing in the flow path to 0.009-inch ID or 0.040-inch ID, depending on
flow rate and backpressure.
