located after inlet valve will remove moderate amounts of particulates.
Flow rate – 40 mL/minute (nominal).
Pressure – 8 to 100 psig. Consult Technical Support for details on sample
handling if the pressure is outside of this range.
Temperature – Temperature must be between 5 and 35 °C.
Chloride level – Chloride levels are read directly in ppb or ppm, when
calibrated with Thermo Scientific Orion 29,600 ppm high level chloride
standard.
Sample alkalinity – Sample alkalinity should be less than 50 ppm CaCO
equivalent. For higher sample alkalinity, contact Technical Support.
