2 The NGC Instrument
The NGC™ instrument ships preassembled with the components necessary to
perform gradient separations. The modular components slide into slots in the
system known as bays. Some modules fit into single-wide bays while others require
double-wide bays. Bays can be converted from one size to the other by adding or
removing a center divider.
Each module has a unique electronic ID that enables the system to recognize its
function when the module is placed into a bay
. For example, the system can
distinguish between a sample inject valve module and a sample inlet valve module
even though they each occupy a single-wide slot.
The position of the module on the system can be changed to optimize the
placement and minimize the length of tubing, r
educing the system swept volume.
The physical location of a module can be easily identified in the overall flow scheme
required to run the application through the ChromLab™ software. Prior to starting a
run, ChromLab performs a system check to ensure that all the required modules are
physically present on the instrument.
This chapter explains in detail the modules that make up the NGC instrument.
