1.1 Outline of Chromaster 5310 Column Oven
(5) Enhancement of Data Reproducibility by Means of
Optimum Preheating
A preheating method developed by Hitachi (FACTS: Flow
Adapted Column Temperature Stability) is employed.
This preheating method makes it possible to provide a
stable peak retention time even if the ambient temperature
varies and to minimize a dead volume for reducing possible
peak diffusion.
(Minimum preheating capacity: 0.63 μL in use of piping
0.1 mm in diameter)
NOTE: This instrument is designed on the presupposition that
preheating is performed before analysis. Be sure to
carry out preheating before proceeding to analytical
operation with this instrument. Otherwise, accurate
analytical results may not be attained.
