Answer 1

The reproducibility of result is called PRECISION.

INSTUMENT PRECISION also called injection precision, the prodicibility of an instrument reading when the same amount of one sample is introduce repeadetly.

INTRA-ASSAY PRECISION the reproducibility of measurement on a uniform material several time on one person on one day with the same equipment

INTERMEDIATE PRECISION also called ruggedness, the reproducibility of measurements by different peoples on different days, on different places of equipmet within the same labarotary.

INTERLABORATRY PRECISION the reproducibility of a measurement from the same sample by different people b in different laboratories.

REAGENT BLANK a blank sample containing all component except for analytet that has been not subjected to the steps of the chemical analysis.

DYNAMIC RANGE concentration interval over which there is measurable responce to the change in analyte concentration.

RESULTS quantities repoerted upon complete of statistical analysis of the data.

FIELD BLANK a blank sample exposed to the environment at the sample collection site and transported in the same manner as other sample back to the lab.

RAW DATA Is individual measurements.

LINEAR RANGE Concentration interval over which the change in detector response is propotional to the analyte quantity.

RANGE Concentration interval ove which linearity, accuracy and precision meets specifications.

METHOD BLANK a blank sample containig all the components except analyte that has been carried through all steps of the chemical analysis including sample preparation.

TREATED DATA amount of concentration determined by using callibration method.

WITHIN- RUN PRECISION the reproducibility of measurements for the sample during the course of single run of an assay.

INTRALABORATORY PRECISION The reproducibility of an instrument reading during a single day, over several runs.

DAY TO DAY PRECISION The reproducibility of measurements on a uniform material over several days.

INEROPERATOR PRECISION The reproducibility of measurements by different people, on the same sample using the same method.

INTERLABORATORY PRECISION The reproducibility of a measurement from the same sample and method by different people in different laboratories.
