Mixer LEDs

The mixer module is fitted with LEDs.

A left green LED indicates the flow is from system pump A.

A right green LED indicates the flow is from system pump B.

Both LEDs light when both pumps are running.

Blinking green LEDs indicate the line to plumb using the Point-to-Plumb

feature.

Detectors

All NGC systems include a detector module that contains a conductivity monitor

and either a single-wavelength UV detector or a multi-wavelength UV/Vis detector.

The single-wavelength UV detector and conductivity module can be replaced with a

multi-wavelength UV/Vis detector and conductivity module and vice versa. Some

configurations include a pH detector module. The pH detector module can be

added as an upgrade to systems that do not offer it as a standard module.

UV Detectors and Conductivity Monitor

The UV detectors measure the UV absorbance of biomolecules as they elute

through the column. The conductivity monitor measures the ionic strength (salt

concentration) of buffers.
