Simultaneous injection of the same sample onto three columns with a 14 port valve

Two position valve application

The 14 port valve permits a variety of plumbing arrangements. This one loads the same sample onto three sample loops for injection onto three different columns. This is used primarily by column manufacturers for QA since samples are injected simultaneously. It has also seen use in labs to perform different parts of the same analysis.
