Optimizing the Stack Configuration
Two Stack Configuration
In case the autosampler thermostat is added to the system, a two- stack
configuration is recommended, which places both heavy modules (1290
Infinity pump and thermostat) at the bottom of each stack and avoids
high stacks. Some users prefer the lower height of this arrangement even
without the autosampler thermostat. A slightly longer capillary is required
between the pump and autosampler. (See Figure 10 on page 37 and
Figure 11 on page 38).
