Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

Question

#19 & 23

Question 23
Which of the following is INCORRECT?
O Calibration determines the relationship between the analytical response and the
concentration of analyte.
O The range in the calibration curve between the relationship of analytical response
and concentration of analyte is the concentration interval over which linearity,
accuracy, and precision are all acceptable.
O The detection limit (DL) or also known as the limit of detection (LOD) is the
smallest concentration that can be reported with a certain level of confidence.
O In external standard method, the signal (SA) is inversely proportional to the
concentration of analyte (CA). Therefore, the formula is SA=KACA where the k is
method's sensitivity.
