Centri PAL3
Sample automation robot for GC–MS
Centri PAL3 is a sample preparation robot for streamlining the preparation of liquid, solid and gaseous samples ready for GC–MS analysis of VOCs and SVOCs.
Integrating with Markes’ Centri sample automation and concentration platform, Centri PAL3 enables unattended, rapid and efficient extraction, preconcentration and injection of VOCs and SVOCs into the GC–MS system.
By minimising manual intervention, Centri PAL3 enhances the efficiency of a variety of sampling techniques, including headspace, liquid injection, SPME and SPME Arrow, aiding the production of accurate, reproducible results.
Why use Centri PAL3?
- Fully automated: Centri PAL3 enables you to deal with a variety of sample types without manual intervention.
- Streamlined workflows: By handling the whole process from extraction through to GC injection, Centri PAL3 shortens sample turnaround times in high-throughput environments.
- Reliability: Because it’s built on the industry-leading PAL3 platform from CTC Analytics (which has over 40,000 systems installed globally), Centri PAL3 can be relied on to deliver robust automation, for consistent results every time.
- Adaptability: Because of its modular design, you can expand the capabilities of Centri PAL3 as your needs evolve, by adding more tools and functionalities.
Centri PAL3 features
- Automated mode switching: Centri PAL3 enables seamless, unattended switching between liquid injection, headspace and SPME applications, enhancing sample extraction versatility.
- ‘Smart’ consumables: ‘Smart chips’ in consumables provide traceability, enabling you to track usage data and helping you achieve reliable, high-quality results over time.
- Range of sample prep options: From liquid extraction to headspace analysis and beyond, Centri PAL3’s extensive sample preparation capabilities reduce or eliminate manual sample processing.
- Modular and upgradable: The system’s modular design allows you to add or upgrade features, ensuring your setup can adapt to future demands.
- Compatibility: Centri PAL3 integrates with:
- Centri 90: Offering preconcentration onto backflushed multi-bed traps for headspace, SPME and SPME Arrow
