Item Description

Displays if a fault in the Type 1 EFC component has occurred.

Type 1

Pressure

Setpoint

0.1 to 100 psi

Displays the programmed column head pressure setting in the

active method.

Actual Pressure 0.1 to 100 psi

Displays the actual column head pressure at the 3800 GC.

Column Flow Displays, in ml/min, the column flow rate calculated from the

column head pressure, column temperature, and column

parameters (carrier gas, column length, and internal diameter).

Linear Velocity Displays, in cm/sec, the column linear velocity calculated from the

column head pressure, column temperature, and column

parameters (carrier gas, column length, and internal diameter).

Total Flow Displays, in ml/min, the total flow rate through the system.

Split State On or Off.

Displays the current split state of the 1079/1177 injector method.

Split Ratio 1 to 10000

Displays the current split ratio of the 1079/1177 injector method.

The split ratio is defined as the Column Flow + the Split Flow / the

Column Flow.

Type 3 Injector EFC Flow/Pressure Status:

Item Description

Ready Yes or No.

The Type 3 Injector EFC component is Ready (Yes) if the

setpoints have been achieved and stabilized. The Type 3

Injector EFC component is Not Ready (No) if readiness to

start a run has not been achieved or if, during a run, the

EFC becomes not ready or goes “out of tolerance”. Some

reasons the GC may go Not Ready during a run are: the

temperature program is too aggressive, the oven door is

opened, the coolant runs out, the power line voltage drops,

etc.

Fault Yes or No.

Displays if a fault in the Type 3 EFC component has

occurred.

Type 3 Flow

Setpoint

0.1 to 100 ml/min

Displays the programmed column flow rate setting in the

active method.

Actual Flow 0.1 to 100 ml/min

Displays the actual column flow rate calculated from the

measured head pressure and column parameters (carrier

gas, column length, and internal diameter).

Pressure Displays, in psi, the measured column head pressure.

Linear Velocity Displays, in cm/sec, the column linear velocity calculated

from the column head pressure, column temperature, and

column parameters (carrier gas, column length, and internal

diameter).
