Learn how to double sample-throughput in analytical testing laboratories using a dual-tower autosampler

This technical note illustrates the effectiveness of a dual-tower autosampler in meeting high-throughput demand for analytical testing laboratories.

Thermo_doubling_sample_throughput_appA confident automation of liquid sample injection in a GC or GC-MS through a robust, reliable, and easy-to-use autosampler is what a high-throughput testing laboratory needs to respond to a heavy workload. The enhanced usability of the Thermo Scientific AI/AS 1610 liquid autosampler makes this platform the fit-for purpose solution, combining operational simplicity with injection mode flexibility. In order to support analytical testing laboratories facing high sample throughput demand, the dual-tower AI/AS 1610 Gemini configuration allows for simultaneous injection on two channels, doubling the throughput achievable on a single GC system, or confirming the same sample on two simultaneous runs.

This technical note summarizes the main features of the Gemini configuration in combination with the Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS) version 7.3, describing the different ways of operations.

The Gemini configuration provides a simple and cost-effective solution to increase laboratory throughput. The simultaneous injections in two channels for unattended analyses of up to 310 samples are achieved with easy-on/off set up and connectivity thanks to the usage of a single, multi-purpose connection between each autosampler and the GC. High-throughput mode or Confirmation mode are easily enabled through Chromeleon CDS, which facilitates the monitoring of multiple parallel sequences on the same GC as well as multiple systems within the same laboratory.

Additional usability features and benefits of AI or AS 1610 liquid autosamplers in single tower or Gemini configuration, in combination with the TRACE 1600 Series GC are key to streamlining daily operations and providing what is required in a high-throughput laboratory for liquid sample injection automation.
