Performance Characteristics and Specifications
4.1
Range
10 to 299mmol/l Chloride.
4.2
Accuracy
Results will be within ±2mmol/l (at the 100mmol/l level) of the values obtained by
standard wet-chemical methods after allowing for pipetting errors.
4.3
Linearity
Results will be within ±1mmol/l in the range 10 to 299mmol/l or ±1% concentration
value whichever is the greater.
4.4
Reproducibility
The values obtained from 20 consecutive titrations of a nominal 100mmol/l solution
will give a coefficient of variance of ≤ 1.5%.
4.5
Stability
The calibration level (mean of five titrations of a standard solution) will change by less
than ±2 Least Significant Digits over the life of any silver anode.
4.6
Response Time
A stable reading will be displayed within 26 seconds of pressing the 'titrate' button, at
a concentration level of 100mmol/l.
4.7
Measurement Capacity
Twenty samples at 100µl or 20µl sample volume, per reagent change.
4.8
Samples
Type
Chloride in solution, having low ionic strength, neutral pH and free of silver halides,
silver reactive constituents (other than chloride), solid matter and high levels of
dissolved solids.
Presentation
By pipette directly into the beaker of Nelson Jameson Combined Acid Buffer.
Volume
100µl or 20µl – user selectable.
