Sample Requirements

Thermo Scientific Orion 2120XP Calcium Hardness Analyzer User Guide
Additional information is listed in the Appendix, Specifications section.
Sample inlet connection – 1/4" NPTF. If particulate matter is present in
the sample, pre-filtration is necessary. The 60 micron stainless steel filter
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 40 °C.
Calcium level – Calcium levels are read directly in ppb or ppm, when
calibrated with Thermo Scientific Orion calcium standards 1 and 2.
Sample alkalinity – Sample alkalinity should be less than 250 ppm CaCO
equivalent. For higher sample alkalinity, contact Technical Support.
