The devices can be found in-home and must be kept within a validated phase having an linked maintenance and servicing plan; the sole supplemental costs are those with the extras required for sampling.
Summary of methodology for Diffusive Uptake Level (UTR) experiments. C is concentration in ng/L or nL/L and m is volume adsorbed on tube in ng or nL. These are subscripted Along with the time period as well as a or P, which means active or passive tube form.
