Gemini Mode

This is an instrument configuration consisting of two autosamplers attached to a single GC. The two samplers inject simultaneously from different sample positions into a separate flow path (inlet, column and one or more detectors) of the GC, thus doubling the sample throughput. Depending on the autosampler and the GC type, either one or two sequences can be run in parallel. For two sequences to be run in parallel, the GC must support dual operation.
