When the result was below the minimum detection limit for the assay, the minimal detectable concentration was used for the analyses.
Where congeners were detected in < 70% of samples, the minimum detection limit was set at zero.
Human FN ELISA Kit (Abnova Co., Taipei, Taiwan), with a minimum detection limit of 0.31 ng/mL, was used to detect FN in serum.
Human PEPD ELISA kit (Cusabio Biotech. Co., LTD, China), with a minimum detection limit of 93.75 mU/mL, was used to detect PEPD in serum.
If a congener was detected in > 70% of the sample population, the minimum detection limit substitutions were made.
Minimum detection limit was determined to be ∼6.6 μM.
This indicated that the minimum detection limit of AgNP-based substrate for carmine is about 10−8 M.
The minimum detection limit (MDL) of this Micro-XRF spectrometer was 9 ppm for the Fe-Kα.
The new system achieved a better linear response (R2= 0.9995) in concentration range from 300 to 2000 ppmv, and achieved a minimum detection limit (MDL) of 630 ppbv.
Preliminary results indicate that a minimum detection limit for chlorine impurity of about 71 mg/L is achievable for an integration time of 30 min.
The minimum detection limit for 3,5-DNSA was 10 nM in 4- 2-hydroxyethyl -1-piperazineethanesulfonic acid (HEPES)–CH3CN (8:2; pH 7.4- 2-hydroxyethyl -1-piperazineethanesulfonic
