5.3 Assembling of Pre-heating Tubing
Chromaster 5310 column oven has a pre-heating section for
preliminary heating (Appended Fig. 1-8). The pre-heating
section has nine grooves (lines) for accommodating the pre-
heating tubing, and the optimum number of grooves to be used
varies depending on the flow rate for the analysis to be used.
Make optimum pre-heating, referring to Table 1 shown below.
