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, reducing 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.
