| Specifications: |
| Heated Devices |
Five heated zones standard: Two detectors, Two inlets,
one auxiliary
Methods stored: Two |
| Split/Splitless
Capillary |
Range to 400°C in 1°C increments
Back-pressure design permits independent adjustment
of split flow rate without affecting column flow
Septum purge built in at 3 ml/min
Accepts columns up to 1.2-mm od
Multimode design includes split and splitless injection
Splitless purge time variable in 0.01-min elements |
| Electronic Pressure
Control |
Pressure Control
> Programming: Three ramps, 0.1-99 psi/minute
> Pressure Range for inlets: 1-100 psi
> Flow range for inlets: 0-450 ml/min
> Constant Flow Mode (Standard): Inlet pressure
is adjusted real time to maintain constant volumetric
flow at column outlet.
> Maximum Channels: Two inlet channels to control
column head pressure, Four auxiliary channels to
control split vent flow (Gas Saver EPC), makeup
gas, fuel gases, or external devices (general-purpose
EPC)
Precision and Accuracy
> Pressure Setpoint Accuracy: +/- 0.1 psi
> Flow Setpoint Accuracy: +/- 0.001 ml/min
> Average Linear Velocity Accuracy: +/- 0.1 0.001
cm/sec. |
