Operation
5. Determine whether the manifold is for a heated chemistry. A heated chemistry
manifold board will have a hole to route the tubing from the heater to the manifold.
For heated chemistries, locate the union connector that holds the two ends of the
tubing needed for the method. Refer to the QuikChem method to determine which
length is needed. Thread both ends through the hole in the manifold. Make both
connections according to the manifold diagram in the QuikChem method. Refer to
section 5.5 on page 55 for more information.
Note: Heater mandrels are available in four prewrapped lengths: 175 cm, 650 cm, 825 cm and
1200 cm. Each prewrapped mandrel is labeled with the length of tubing it carries.
