Flow Cell Label

One or more flow cell labels are present on the flow cell, which contain information such as flow cell type, part number, and serial number.

Flow Cell Identification Chip

An identification (ID) chip on the flow cell stores information, including the flow cell type and the serial number of the flow cell. The ID chip also stores data during operation, such as the exposure time to the light.

When the flow cell is installed, the detector reads the data from the chip and transfers the flow cell data to the chromatography data system.

Heat exchanger

Standard flow cells and semi-micro flow cells are equipped with a built-in heat exchanger.

The heat exchanger helps to adapt the temperature of the mobile phase to the flow cell temperature before the mobile phase enters the optical flow path within the flow cell. Note that the volume of the heat exchanger and inlet capillary influences the retention times and peak widths.

Flow Cell Types

The detector is shipped with a diagnostic cell. Replace the diagnostic cell with a flow cell that is appropriate for your application. Depending on the application needs, different types of flow cells are available for the detector.

For flow cell ordering information, see Optional Accessories.

For the flow cell specifications, including, for example, materials in the flow path and pressure limit, see Flow Cell Specifications.
