Quality control measures included analysis of initial and continuous calibration verification standards, procedural blanks, duplicate samples, and spiked samples.
Quality control measures included initial and continuous calibration verification standards, procedural blanks, duplicate samples, spiked samples, and the National Institute of Standards and Technology Standard Reference Material for trace elements in water (NIST SRM 1643d).
Quality control measures included: analysis of initial calibration verification standard, continuous calibration standard, procedural blanks, and duplicate samples.
Quality control measures included: analysis of initial calibration verification standard, continuous calibration standard, procedural blanks, duplicate samples, spiked samples, National Institute of Standard and Technology Standard Reference Material (NIST SRM) 1643e-trace elements in water and NIST SRM955b-lead in blood.
Calibration verification samples were analyzed prior to analyzing samples.
ought to be organised in continuous calibration with those practices.
The calibration, verification, and validation of calcium (Ca), chloride (Cl), and sulfate (SO4) module of the Lake Okeechobee Environment Model (LOEM) was completed.
In particular, a systematic calibration, verification and validation procedure of the implementation of a solid propellant constitutive model was developed.
Sensitivity of the method was examined by establishing the limit of quantitation (LO Q, the half limit of quantitation (1/2 LOQ), and the introduction of the initial calibration verification standards (ICV) in the calibration curve standards.
It is shown that the model based on REV size agrees well with the experimental results over the entire migration period including calibration, verification and validation processes.
Quality control (QC) measures included analysis of the initial calibration verification standard (National Institute of Standard and Technology Standard Reference Material 1643e, trace elements in water; Gaithersburg, MD, USA), a 1-ng/mL mixed-element standard solution, continuous calibration standards, and a procedural blank.
