WebA highly sensitive ELISA is critical for early diagnosis and biomarker discovery of various diseases. Although various ELISA technologies have been developed with high sensitivity, they are limited by poor repeatability, high cost, the dependence on complex equipment and/or a prolonged reaction time.
Webating repeatability, only the 624 column was used for calcula-tion of RSD’s. Other configurations using dual FID’s (624 and INNOWax columns) or FID/MSD are also illustrated. The static headspace based method has historically suffered from poor repeatability when analyzing solvents at or below their USP 467 limit concentrations.
