Shimadzu - Model GC-8A -Single Detector Gas Chromatograph
Economical and Rugged: The GC 8 is a single inlet, single detector, gas chromatograph. It`s very simple yet robust design makes it perfect for a teaching lab or for a dedicated application in a QC environment. Its all metal construction provides for a GC that is very rugged and can easily withstand the rigors of an industrial QC setting. This system offers a choice of three packed column detectors: FID, ECD or TCD.

Large-capacity, cubic oven
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.
Two-stage overheat prevention for protection of columns
If the temperature exceeds the programmed (preset) temperature by 30°C, the heater will be automatically turned off. If the temperature reaches about 420°C, the heater will be automatically turned off.
Temperature control offers excellent stability and response
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.
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.
All GC-8AP series instruments incorporate an internal temperature controller for digital temperature settings.
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.
Adding the optional CLH-800 capillary column holder allows simple mounting of the capillary column for both split and splitless sample injection.
