10.4 Performance characteristics
10.5 Environment
10.6 Process
10.7 Mechanical construction
In accordance with ISO 15839
The performance characteristics have been determined in accordance with ISO 15839, Annex B. 300 μ l sample were
metered into the TOCII (CA72TOC-B1A0B1) per measurement. This resulted in a measuring range from 4 to 800 mg/l.
The following data refer to this device.
Slight deviations should be factored in if applying the performance characteristics to other measuring ranges.
LOD (limit of detection) 0.75 % of end of measuring range
LOQ (limit of quantitation) 2.5 % of end of measuring range
Short-term drift 0.5 %/day
Repeatability precision at 20 % of the measuring range 0.4 %
Resolution limit at 20 % of the measuring range (LDC) 1.1 %
Systematic measured value deviation at 20 % of the measuring range (BIAS) 0.4 %
Repeatability precision at 80 % of the measuring range 1.6 %
Resolution limit at 80 % of the measuring range (LDC) 4.6 %
Systematic measured value deviation at 80 % of the measuring range (BIAS) 2.4 %
Ambient temperature
range 5 to 35 °C (41 to 95 °F)
Humidity 10 to 90 %, non-condensing
Degree of protection IP 54
Sample temperature 0 to 40 °C (32 to 104 °F)
Sample flow rate 20 ml/min (0.32 US gal/hr)
Sample feeder volume 90 ml (3 fl.oz)
PA-2, PA-3 and PA-9 are available for selection as sample preparations.
Sample consistency Aqueous
Flammable substances should not occur in combustible concentrations - sample dilution is
then necessary.
Sample supply Non-pressurized infeed to the analyzer from sample preparation.
