Markes Centri 90 Sample Enrichment Platform

Markes Centri 90 Automated Sample Enrichment Platform is designed to maximize sensitivity for high-throughput GC-MS Analysis of VOCs / SVOCs in solids, liquids, and gases.

The Markes Centri 90 Automated Sample Enrichment Platform is an automated platform for routine sampling and enrichment by headspace, SPME and SPME Arrow, with additional chromatographic performance provided by trap-based pre-concentration.

Along with advanced options for water management, Markes Centri 90 provides excellent analytical performance across a wide analyte range, and especially for early-eluting VVOCs. This is due to its world-leading, cryogen-free back-flush trapping capabilities.

Conventional GC injection modes remain available, allowing you to maintain existing workflows while also evaluating the benefits of pre-concentration using the focusing trap.

Built-in Multi-Gas capabilities in the Centri 90 allow a choice of carrier gases (helium, hydrogen, and nitrogen) to be used, enabling cost-savings and future-proofing your lab.

Features

Centri 90 can purchased as a base unit (used in conjunction with existing third-party PAL3 Series II, and compatible PAL3 Series I rails, with or without automatic tool changing capability) or with robotics
Sample extraction from a variety of sample matrices using a range of dedicated sampling tools:
- Headspace (HS) and HS–trap.
- SPME and SPME–trap.
- SPME Arrow and SPME Arrow–trap.
When configured, a tube autosampler (optional upgrade to Centri 180 configuration), enables analysis of:
- Thermal desorption tubes.
- HiSorb™ high-capacity sorptive extraction probes.
Integrated inlet for injection/desorption of HS, SPME and SPME Arrow samples to the focusing trap. Centri 90 is designed for dual carrier gas compatibility.
Electrically-cooled, cryogen-free focusing trap enables analysis of compounds over a wide volatility range, including reactive and labile species:
- Simultaneous analysis of VVOCs, VOCs and SVOCs.
- Quantitative recovery of labile compounds.
- Quantitative recovery of high-boiling compounds up to n-C44.
Sample stacking and enrichment: Combine multiple vial extractions onto the focusing trap prior to injection to the GC. Inert, uniformly heated flow-path ensures complete recovery of analytes throughout the analytical system. Use of automated tool-change robots allows optimum unattended sequencing of HS, HS–trap, SPME, SPME–trap, SPME Arrow, SPME Arrow–trap and any other robot capability configured.
Direct sampling from vials placed in vial tray with HS–trap and SPME Arrow–trap using Centri 90 methods only.
Supports PAL3 standard and custom scripts, allowing flexible sequencing with Centri 90 methods, including liquid handling for addition of internal standard and derivatizing agent. Liquid injection and PAL3 scripts, such as HS, SPME and SPME Arrow, can be performed directly to the GC inlet (80 cm, 120 cm, or 160 cm rail only).
