Column Oven
Large-capaci ty, cubi c ove n
Almost cubic in shape, the column oven opens entirely at the
front, making changing columns simple and easy. The column
oven's door opens and closes by a simple one-touch operation.
The lightweight door moves extremely smoothly.

If the temperature exceeds the programmed (preset)
temperature by 30°C, the heater will be automatically turned
o. If the temperature reaches about 420°C, the heater will be
automatically turned o.
Rapid he at ing and cool in g
ch aracteristi cs
Rapid heating and cooling characteristics of the column oven
are also important for a gas chromatograph. Fig. 4 shows that
heating from 100°C to 350°C requires just 12 minutes, while
cooling takes less than one minute and re-stabilizing at the
initial temperature takes about three minutes.

Excellent temperature control of the column oven is essential
for a gas chromatograph. Fig. 2 shows the response and stability
when the column oven's temperature setting is changed from
100°C to 101°C. It shows that the oven responds rapidly to a
changed temperature setting and is able to immediately achieve
stable temperature control.

Sample Injection Ports
Easy-to-use on-column sample
injection ports
The standard injection ports are on-column type. Since sample
solution is directly injected into the head of a glass column, the
decomposition and adsorption of sample components are
minimized.

Capillary column adapter
Adding the optional CLH-800 capillary column holder allows
simple mounting of the capillary column for both split and
splitless sample injection.
