Key Features of Welch Preparative Chromatography Systems
High-Precision Flow Control
Advanced microprocessor-driven pump technology ensures exceptionally accurate flow delivery across low and high flow rates. Multi-point flow calibration and solvent compression compensation maintain consistent performance from low pressure to high pressure operations.
Ultra-Low Pulse Pressure
Cam-curve compensation and real-time pulse monitoring significantly reduce pressure fluctuations. This minimizes baseline noise, improves detector stability, and ensures cleaner peak shapes during gradient or isocratic runs.
Flexible Gradient Programming
A high-pressure binary pumping system allows creation of unlimited gradient profiles. Whether for fast method development or high-resolution separations, users can optimize gradients to achieve excellent results while minimizing solvent consumption.
High-Sensitivity Dual-Wavelength Detection
The system is fully controllable via both workstation software and an integrated touchscreen panel. Operators can easily adjust flow rate, pressure, wavelength, and collection parameters — simplifying routine workflows.
