Typical EMC Deviation ±2 µg/L
Light Source
Light Emitting Diode
Light Detector
Silicon Photocell with narrow band interference filter @ 466nm
Method
Adaptation of the ASTM Manual of Water and Environmental Technology,
method D1385-88 for natural and treated water. The reaction between
hydrazine and the liquid reagent causes a yellow tint in the sample.

PRECISION AND ACCURACY

Precision
Precision
Precision is how closely repeated measurements

agree with each other. Precision is usually
expressed as standard deviation (SD).

result to the true value.
Although good precision suggests good accuracy,
precise results can be inaccurate. The figure
explains these definitions.
In a laboratory using a standard solution of
100 µg/L hydrazine and a representative lot of
reagent, an operator obtained with a single
instrument a standard deviation of 3 µg/L.
