Thermo Scientific Dionex UltiMate 3000 Series Autosamplers WPS-3000PL (RS) and WPS-3000FC

Importance of the Topic

High-performance liquid chromatography (HPLC) remains a cornerstone of analytical chemistry for pharmaceutical, environmental, and biotechnological applications. Reliable, automated sample introduction is essential for achieving high throughput, precision, and reproducibility. The Thermo Scientific Dionex UltiMate 3000 Series WPS-3000PL (RS) and WPS-3000FC autosamplers offer versatile configurations for full-loop, partial-loop, and microliter pick-up injections, as well as multidimensional fraction collection and biocompatible operation. These instruments enhance laboratory productivity and method robustness in research, quality control, and industrial analytics.

Aims and Overview of the Study

This document provides a detailed guide to the WPS-3000PL (RS) and WPS-3000FC autosamplers, covering:

• System layout and major components
• Safety precautions and intended use
• Instrument installation and integration with Chromeleon and DCMSLink software
• Preparation, operation modes, and maintenance procedures
• Troubleshooting and preventive service

It aims to support end users in setting up, configuring, and maintaining their autosampler for optimum performance.

Methodology and Used Instrumentation

The autosamplers employ a pulled-loop injection principle controlled by an external syringe valve and Cheminert switching valves. Key hardware elements include:

• Syringe valve with programmable draw and dispense speeds
• Injection valve (6-port) and, for WPS-3000FC, a fractionation valve (6-port)
• PEEK or stainless steel fluidics for standard, biocompatible, and high-pressure applications
• Biocompatible PAEK valves and nanoViper capillaries for biomolecule analysis
• Integrated wash port, leak sensor, and carousel accommodating up to 216 vials or three well plates
• Optional temperature control (4–45 °C) for sample cooling or heating

Software control is provided via USB 1.1 connectivity to Chromeleon (Timebase Class 1, Fraction Collection licenses) or DCMSLink, enabling both direct and automated operation.

Main Results and Discussion

Extensive performance testing has demonstrated:

• Injection precision: RSD < 0.4 % for 1 µL full-loop and < 1 % for 200 nL partial-loop (caffeine in water)
• Linearity: correlation coefficients > 0.9995 in low-µL range
• Zero sample carry-over (< 0.02 % with external needle wash)
• Rapid cycle times: < 30 s per 1 µL injection
• Reliable leak detection, vial/plate recognition, and needle overload protection
• Predictive wellness monitoring for consumables and service intervals

These features support robust, unattended operation and consistent data quality.

Benefits and Practical Applications

Key advantages include:

• Flexibility for routine HPLC, nano-LC, and biocompatible analyses
• Automated fraction collection for multidimensional workflows
• Reduced downtime via easy maintenance and predictive performance alerts
• Enhanced sample integrity through temperature control and inert fluidics
• Full integration with Chromeleon and other data systems for batch-wise or sequence-driven analysis

Industry applications span pharmaceutical formulation, proteomics, QA/QC testing, and environmental monitoring.

Future Trends and Potential Applications

Emerging developments likely to shape autosampler use include:

• Integration with artificial-intelligence–driven method optimization
• Miniaturized, microfluidic sampling for single-cell and ultra-low-volume analyses
• Enhanced connectivity to laboratory information management systems (LIMS)
• Expanded multidimensional fractionation strategies with real-time spectral decision making
• Remote monitoring and cloud-based maintenance prediction

Such advances will further automate workflows, improve data reliability, and extend analytical capabilities.

Conclusion

The Thermo Scientific Dionex UltiMate 3000 WPS-3000PL (RS) and WPS-3000FC autosamplers deliver high precision, flexible injection modes, and advanced fraction collection in a robust, user-friendly package. Combined with Chromeleon control, they enhance throughput and data quality across diverse HPLC applications. Strategic maintenance and firmware management support long-term reliability, while upcoming software and hardware innovations will continue to elevate chromatographic automation.
