Thermo Scientific Orion 2117HL High Level Chloride Analyzer User Guide
The Thermo Scientific Orion 2117HL chloride analyzer software has
default values to accommodate a 0.50 mL addition of standard 1,
three 0.50 mL additions of standard 2 and flow cell volume of
approximately 95 mL.
The operator has the option to use alternate standards by changing, in
the setup mode, the flow cell volume, the standard 1 and standard 2
concentration values and the standard 1 and standard 2 volume values to
be used.
