MultiPurpose Sampler - MPS XL for GC - Specifications

Importance of the Topic

The adoption of automated, multipurpose samplers for gas chromatography (GC) is crucial for modern analytical laboratories. By combining high throughput, precision and flexibility, systems like the MultiPurpose Sampler (MPS XL) eliminate manual variability, accelerate sample preparation and improve data quality, supporting applications across environmental monitoring, food safety, pharmaceuticals and industrial QA/QC.

Study Objectives and Overview

This whitepaper presents a concise overview of the MPS XL for GC, outlining its configurations, performance specifications and accessory options. The goal is to highlight how the platform addresses diverse sample introduction needs—liquid injection, headspace, solid phase microextraction (SPME)—and integrates sample handling modules to streamline analytical workflows.

Methodology and Instrumentation

The MPS XL is built around an XYZ robotic arm carrying a syringe‐only concept. Key instrumentation features include:

• Sample Trays: Up to four thermostated trays (4…200 °C) holding various vial sizes (1 mL to 100 mL).
• Injection Modules: Interchangeable modules for liquid, headspace and SPME sampling, each with dedicated syringe options and temperature control.
• Agitators/Incubators: Multiple designs support vial agitation or incubation (10…200 °C) at speeds up to 1 500 rpm, with peltier or liquid cooling options.
• Wash Station: Configurable with 2–4 solvents and reservoirs (10…1 000 mL) for automated needle cleaning.
• Additional Accessories: Dilutor module, fiber bake‐out station, automated SPE, dynamic headspace (DHS), thermal desorption and liner exchange options.
• Control Software: GERSTEL MAESTRO ensures intuitive method setup, context‐sensitive help and advanced routines (sandwich injection, standard addition, multiple prep‐ahead).

Main Performance Results and Discussion

Under standard conditions, the MPS XL achieves:

• Liquid Injection Precision: < 0.8 % RSD and carryover < 0.08 % across volumes 0.12…1 000 µL.
• Headspace Sampling Precision: < 1.0 % RSD with carryover < 0.05 % for volumes up to 2 500 µL.
• Flexible Volume and Speed: Injection and fill speeds from 0.05…500 µL/s (liquid) and 10…1 000 µL/s (headspace), supporting large‐volume and sandwich techniques.
• Wide Environmental Tolerance: Operating at 10…40 °C and up to 95 % humidity, with global voltage and EMC certifications for reliable use in diverse laboratories.

Benefits and Practical Applications

The MPS XL significantly enhances laboratory productivity by reducing manual handling and enabling unattended operation. Practical advantages include:

• High Throughput: Hundreds of samples per tray with automated prep and injection sequences.
• Method Flexibility: Seamless transition between liquid, headspace and SPME analyses without hardware reconfiguration.
• Reproducibility: Tight control of temperature, volume and cleaning steps minimizes variation and contamination.
• Custom Workflows: User‐definable routines and accessory integration support niche applications like multiple headspace enrichment or automated SPE.

Future Trends and Potential Uses

Emerging directions for multipurpose samplers include tighter integration with data analytics and AI‐driven optimization, further miniaturization of sample volumes for green chemistry, and expanded automation of preparative steps such as derivatization and inline cleanup. Integration with laboratory information management systems (LIMS) and cloud platforms will also support remote monitoring and predictive maintenance.

Conclusion

The MultiPurpose Sampler MPS XL for GC represents a versatile, high‐performance platform that addresses the evolving demands of modern analytical laboratories. Its modular design, broad temperature and volume capabilities, and robust software control deliver unmatched flexibility and reproducibility, positioning it as a valuable asset for diverse GC applications.
