Lower-limit temperature

When INJ and DET temperature is 300°C, room temperature + 15°C

When INJ and DET temperature is 150°C, room temperature + 10°C

Additional cryogenic equipment is required for controlling at lower temperatures than those above.

Cooling speed

Approx. 9 min to reduce from 399°C to 100°C with room temperature of 25°C.

Approx. 14 min for reducing from 399°C to 50°C with room temperature of 25°C

Sample injection port unit (Either one of the following units is provided)

Single injection port unit:         For packed glass column, combination type of glass

insert and on-column injection,          1 flow line

Dual injection port unit:           For packed glass column, combination of glass insert

and on-column injection,                    2 flow lines

Injection port unit for                Exclusive injection port for capillary analysis

Overheat protection circuit

3 circuits

1.       450°C-fixed independent protection circuit.

2.       Protection circuit for which the upper- lirnit temperature can be set via key operation.

3.       Overheat protection circuit by CPU abnormality detection

Combination of Detectors

1.       Four detectors at maximum from among TCD, FID, ECD, FPD, and FTD can be simul­taneously installed to the detector oven of the GC main body. Two TCD detectors cannot be set simultaneously.

2.       Only two types of detector controllers (except FTD) can be installed simultaneously to the control section of the GC. Another unit should be applied for installing three or more detector controllers, or FTD.
