CHRONECT® Quantos

Importance of the Topic

The accurate and automated dosing of powder samples is a critical step in many analytical workflows. Manual handling can introduce errors, variability and slow down high-throughput environments. By automating this step, laboratories achieve greater precision, reproducibility and operational efficiency, supporting quality assurance and advanced research in pharmaceutical, chemical and materials analysis.

Aim and Overview

This product information describes the development and functionality of CHRONECT® Quantos, an integrated system for fully automated powder dosing. Developed in collaboration by Axel Semrau®, METTLER-TOLEDO GmbH, Jüke Systemtechnik GmbH and Trajan Scientific and Medical, the system extends CHRONECT® robotic sample preparation with precise dosing and weighing. The overview covers system components, operating principle and configuration options.

Methodology and Instrumentation

The CHRONECT® Quantos platform combines a CHRONECT Bionic robot with the METTLER-TOLEDO Quantos Powder Dosing System and CHRONECT Robotic XYZ autosampler. Key components include:

• CHRONECT Bionic cooperative or industrial robot for vial handling
• Quantos Powder Dosing System with a dosing module and integrated precision scale
• CHRONECT Robotic XYZ system featuring a PAL autosampler by CTC Analytics
• CHRONOS control software for seamless orchestration of dosing, weighing and liquid handling

The workflow begins with CHRONECT Bionic placing the target vial under one of up to 32 dosing heads. The Quantos module dispenses a preprogrammed powder mass directly onto the scale, verifies the weight and returns the vial for subsequent liquid handling or analysis.

Main Results and Discussion

Implementation of CHRONECT Quantos demonstrated:

• High-precision powder dosing with automated verification reduces variability compared to manual preparation
• Seamless integration with existing robotic platforms extends the automated workflow without manual intervention
• Modular design supports cooperative or high-speed industrial robots to meet different throughput requirements

The described figures illustrate the sample handling sequence and robot configurations, confirming reliable performance and flexibility across laboratory settings.

Benefits and Practical Applications

Key advantages of the fully automated powder dosing system include:

• Elimination of manual weighing errors and contamination risks
• Increased sample throughput by automating time-consuming steps
• Compatibility with standard XYZ robotic workstations and autosamplers
• Robust investment with scalable configurations for R&D, QA/QC and production environments

This solution is particularly relevant for pharmaceutical development, formulation studies, environmental analysis and material science, where reproducibility and traceability are essential.

Future Trends and Opportunities

As laboratories advance towards fully digital workflows, future developments may include:

• Integration of artificial intelligence for adaptive dosing strategies
• Expanded dosing head chemistries for challenging powders
• Enhanced connectivity with LIMS and cloud-based data analytics
• Miniaturization for microdosing and single-particle analysis

Such trends will further streamline sample preparation, enable predictive maintenance and support complex multi-step assays.

Conclusion

CHRONECT Quantos represents a major step in laboratory automation by combining precise powder dosing with established robotic sample handling. This integrated solution enhances accuracy, throughput and operational robustness, meeting the evolving demands of analytical laboratories.
