Sentence examples for neat standards from inspiring English sources
Six lots of blank biological matrices were extracted each in triplicates and postspiked with the aqueous standard at the mid-QC level and compared with neat standards of the same concentration in alternate injections.
The efficiency of carbinoxamine enantiomers and IS extraction from human plasma was determined by comparing the responses of the analyte extracted from six reproduce QC samples with the response of analyte from neat standards at equivalent concentrations by a liquid-liquid extraction process.
