Abstract
A method of performing liquid chromatography (LC) with an LC system including an LC column and an analyzer includes delivering a transport liquid to an open port interface (OPI) of a sample receiving circuit, wherein the sample receiving circuit includes a sample transfer chamber. A sample is ejected from a sample holder into the OPI with a non-contact ejector. The transport liquid and the sample are received in the sample transfer chamber. The sample transfer chamber is decoupled from the sample receiving circuit. A solvent is delivered to the analysis circuit. The sample is pushed from the sample transfer chamber with the solvent. The sample and the solvent is passed through the LC column to produce an eluent. The eluent is analyzed with the analyzer.
