Figure 2-23 shows the flow paths through the sample syringe valve ports
for the two valve positions:
•
In the needle position, flow is between ports A–B, C–D, and E–F.
•
In the flush position, flow is between ports A–F, B–C, and D–E.
Figure 2-24 shows the fluid connections to the sample syringe, flush
reservoir, sample prep syringe, and reagent reservoirs when the sample
prep option is installed.
