Dispensing systems for individual syringes preparation are preferably based on direct radioactivity determination using dose calibrators: in this case the dose calibrator is the critical component, whose calibration status need to be verified during OQ (see below).
The human permeability data are based on direct in vivo determinations in the human gastrointestinal tract with a single-pass perfusion system.
A very simple and quick analytical method, based on direct aqueous injection, for determination of halogenated solvents in refinery water and wastewater, is described.
Estimates of total cell mass based on direct microscopic counts and DCW determinations revealed that the average mass of a cell in − N was 81% of that in + N, confirming that the change in TAG was independent of changes in DCW.
The first approach provides to use models for the estimation the landfill gas production, whereby the second and the third approach are based on direct measurement campaigns on the landfill surface: for the determination of the methane concentration or for the direct measurement of the odour concentration, respectively.
The specific activities are based on direct [H]-dThd phosphorylation activity measurements and on determinations of STK1 protein levels using immunoaffinity/Western blotting analyses.
A novel and sensitive label-free aptasensor has been developed based on direct electrodeposition of gold nanoparticles (AuNPs) on NH2-reduced graphene oxide (rGo-NH2) modified electrode for the determination of adenosine triphosphate (ATP).
A novel method for the simultaneous determination of 3-nitrotyrosine (NT) and 3-chlorotyrosine (CT) in human plasma has been developed based on direct analysis in real time tandem mass spectrometry (DART MS/MS).
Fourth, all patients underwent serological determination of thyroid autoantibodies based on a direct Anti-TPO radioimmunoassay kit for quantitative determination of anti-TPO autoantibodies (Immunotech, Prague, Czech Republic).
