Flow-through-needle injector

Flow-through-needle injector
Topic LCI-USG-0030, Last Updated 11/08/2024

The FTN mechanism facilitates the transfer of LC methods and improves injection accuracy.

The sample manager's FTN mechanism aspirates a sample and holds it in the sample needle, prepared to inject the sample onto the column. The needle serves as part of the injection flow path when the sample is pushed onto the column.

The FTN mechanism decreases cycle time for small-volume injections and does not require learning new injection modes. Mobile phase gradients pass through the needle during injection, ensuring complete sample recovery.
