Subject: [ISOGEOCHEM] Offline Exetainer Flushing
Has anyone developed an off-line method for flushing a full batch (96) of exetainers? I am unsure of the cost of a stand alone CTC Analytics PAL autosampler. It would be great to free up the Gasbench-IRMS for only measurements and let the exetainers/tubes be prepped separately. Any thoughts?
