Sampling and analysis
Sampling mechanisms
The sample probe (SPP) aspirates sample from the dilution tray (DTT) and dispenses it
into reaction tray (RRV) cuvettes for analysis, according to specified conditions. The
sampling pump (SP) handles the aspiration and dispensing functions.
Sampling operation
At initialization, the SPP moves (in the up position) to the RRV cuvette, then stops above
the wash port. The pumps stop when the SPP is positioned over the RRV cuvettes.
Each sampling cycle consists of these steps:
1. The SPP moves to the aspiration position of the DTT and aspirates the sample.
2. The SPP moves back to the wash port, where deionized water washes the SPP’s
outside surface.
3. The SPP moves to the RRV and dispenses the sample into a cuvette.
4. The SPP returns to the wash port, where degassed water washes the inside and
outside of the SPP.
The SPP is now ready for another cycle.
