Flow Cell Guidelines: Flow Cell Guidelines: Flow Cell Guidelines: Flow Cell Guidelines: Flow Cell Guidelines:
Do not exceed pressure specification of flow cell.
Strictly follow established operating procedures from regulatory or governing
bodies.
Avoid trapped gas in flow cell especially on the measuring sensors.
Maintain a constant flow rate.
Freeze protection is required if flow cell is left unattended.
If flow cell and probe is used in direct sunlight it is advised to cover flow cell
with foil or other material after determining sensors are free of gas bubbles.
