During which of the following conditions is the blank correction necessary?
A. If sample concentration rises in linear response region
B. If sample concentration falls in linear response region
C. If sample concentration rises in non-linear response region
D. If sample concentration falls in non-linear response region
Answer:D
During which of the following conditions is the blank correction necessary?
A. If sample concentration rises in linear response region B. If sample concentration falls in linear response region C. If sample concentration rises in non-linear response region D. If sample concentration falls in non-linear response region
Explanation: The blank correction is necessary if sample concentration falls in non-linear response region. This is the constant background for all measurements.
