what is the difference between system precision and method
precision?
Answer Posted / pratima bhandarkar
The system precission is checked by using standard chemical
substance to ensure that the analytical system is working
properly.In this retention time and area of six
determinations is measured and % RSD should be calculated.
In method precission, a homogenous sample of single batch
should be analysed 6 times. This indicates whether a method
is giving consistent results for a single batch.In this
analyse the samplesix times and calculate known, unknown
and total impurities in the sample calculate the %RSD.
