Importance of Rapid Separation LC

In modern analytical laboratories, rapid separation liquid chromatography (RSLC) addresses the growing demand for high-throughput and high-resolution analyses. By combining ultrafast gradients, optimized hardware, and advanced data processing, RSLC systems significantly reduce analysis time while maintaining or improving separation efficiency. This capability supports critical applications in pharmaceutical development, quality control, environmental monitoring, and food analysis, where fast turnaround and confident identification of analytes are essential.

Study Objectives and Overview

This document presents the design, capabilities, and performance of the Thermo Scientific UltiMate 3000 RSLC systems. It highlights system components, flow-pressure footprints, and integration with Chromeleon chromatography data system software. Practical examples illustrate speed gains, resolution improvements, and flexible workflows including dual-pump configurations, automated method scouting, and multidimensional LC.

Methodology and Instrumentation

• Pumping Modules: Binary, quaternary, or dual-gradient RS pumps enabling pressures up to 100 MPa and flow rates up to 8 mL/min.
• Sample Handling: In-line split-loop for 15-second cycle times and well-plate sampler accommodating up to 500 µL injections.
• Column Compartment: Thermostatted unit (5–110 °C) supporting up to 12 columns; zero-dead-volume Viper fingertight fittings.
• Detectors: Diode array (up to 200 Hz), variable wavelength, fluorescence, charged aerosol, electrochemical, and MS interfaces.
• Columns: Range of UHPLC columns (Accucore, Hypersil Gold, Syncronis, Acclaim RSLC) with particle sizes down to 2.2 µm.
• Software: Chromeleon CDS for instant data processing, method transfer, automated method scouting, and integrated reporting.

Main Results and Discussion

• Speed and Resolution: Up to 50× faster than conventional HPLC with retention of high peak capacity; example separation of 10 analytes in 10 seconds at 100 °C and 3.7 mL/min on a 30×2.1 mm, 1.8 µm C18 column.
• High-Throughput Examples: Analysis of sweeteners and acids in soft drinks in under 40 seconds; baseline separation of 29 pesticides in less than 9 minutes; UHPLC and conventional LC performance compared for retention time and area reproducibility (RSD < 0.4 %).
• Small Particle Columns: Use of 2.2 µm particles achieves 2× speed with 96 % of original resolution retained; van Deemter curve analysis underscores efficiency gains at higher linear velocities.
• Dual RSLC Configurations: Parallel and tandem LC doubling throughput; automated switchover extends operation into nights and weekends, maximizing instrument utilization.
• Automated Method Scouting: Ultrafast screening of columns, buffers, solvents, and temperatures with automated execution and evaluation; bubble-chart visualization aids quick selection of optimal conditions.
