Injected mass
WebbGenerally one would reduce the mass injected by factors of 10 (or 2 for trace analysis) until the retention time and peak symmetry stabilize. When moving from one column to another with different surface area and pore volumes, one can use the following approximation (eqn. 1) for the phase ratio of a packed bed (ratio of silica surface to … Webb9 okt. 2024 · The injected mass of small molecule radiopharmaceuticals on classical PET–CT tomograph are normally in the range of 0.1–10 µg. Assuming a fivefold increase in scanner sensitivity, administered radiotracer masses in the picogram range would be thus routinely achievable.

WebbWithin this radius, we inject mass and energy using a Gaussian kernel with 1D dispersion σ = 0.1R kernel, weighted by the cell masses and truncated at R kernel. This kernel mass was chosen so that R kernel is always larger than R E ; this means some energy will be injected outside the cooling-disabled region and will be lost rapidly, but the amount so …
