Markes International has extended its Centri® automated sample extraction and enrichment platform to include additional functionality and the ability to increase or decrease the level of automation. The modular Centri platform can now be configured in a more user-defined way than before and makes trap-enabled preconcentration, extraction and enrichment available to a wider range of laboratories. The new capabilities include smart microchip technology for headspace, SPME and SPME-Arrow sampling accessories. The chip automatically loads parameters such as syringe/fibre type, provides details on minimum and maximum recommended conditioning temperatures and records start of usage when installed, providing improved reliability, traceability and ease-of-use. Liquid handling (e.g. addition of derivatisation reagent or internal standard) enables automated, unattended sample preparation. It supports trap-enabled SPME-Arrow, expanding the portfolio of extraction and enrichment techniques available. Automated GC inlet injection, replacing this normally manual step frees up the user’s time. Intelligent diagnostics for automated system self-checking, including valve operation and leak isolation along the flow path. The ability to identify where a leak is enables rapid corrective action, in some cases without the need for an engineer to be available, decreasing instrument downtime.
