≤ 1% Coefficient of variation (C.V.) for 20 consecutive samples
using 10ppm Na set to read 50.0.
Readings taken at 20 second intervals.
N.B. C.V. is defined as: the sample standard deviation X 100
And sample standard deviation as:
Where x is the reading, x is the mean readings of the series and n is
the number of readings.
Better than 2% when concentration of 3ppm Na and K and 5ppm Li
are set to read 100.
Interference from Na, K and Li when equal in concentration to the
test element will be less than 0.5%.
Better than 2% over 5 minutes when continuously aspirating 10ppm,
sample set to read 50.0.
Zero drift better than 2% per hour.
N.B. Note warm up requirement.
Between 2 and 6ml/minute.
Nominal 1.00 volt for readout of 100.0.
The flame must be alight for at least 15 minutes to ensure
achievement of the above stated specifications.
Electrical:
90-125V or 190-250V @ 50/60Hz.
