The sample flow-through volume of liquid or gas is adjustable and unlimited.
2.4 0.6 5.8 1.8 7.0 1.0 6.0 1.0 5.3 V/V 0 indicates the ratio of the total groundwater flow-through volume to the packer volume of the sampling intervals in the boreholes.
The concentrations of PM2.5 and PM10 at our sampling site were estimated by the net weight of each sample (average weight of the two PM2.5 samples) divided by the 23 h flow-through volume per sampling day (to avoid microbial contamination, samples were not kept under 45% relative humidity at 20 °C as typically required for PM measurements).
For GPC a Dionex HPLC, equipped with a UV-detector (Dionex PDA 100, detection wavelength 230 nm) and a 14C-detector (Raytest Ramona Star, flow through, cell volume 200 µl) connected in series was used.
The solution was run at 1 mL/min through a low volume flow-through cuvette (Hellma Analytics, Germany) and adsorption was measured at 405 nm using a UV VIS spectrophotometer (Genesys 10S, ThermoFisher, USA).
In order to investigate the transport of manufactured nanoparticles through small saturated rock columns, a simple and inexpensive laser nephelometer was developed which incorporates a low volume flow-through cell in order to provide a continuous record of the elution of particles from the column.
The platform comprises a cooled microautosampler, an integrated system for microcolumn HPLC, and a capillary reversed-phase column that is interfaced to matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS) system via a low internal volume flow-through microdispenser.
The protocol is based on magnetic coupling of mRNA and retaining the nucleic acid in low volume flow-through columns for greatly simplified handling.
Current flow through the film volume was normal to the film substrate.
The power Doppler images at peak enhancement were analyzed to determine percentage area of the tumor with flow (PAF) and color-weighted flow area (CWFA), representing relative blood volume flowing through the unit volume of the tumor in the image plane [22], [23].
In this controlled field study, nitrate-rich, site groundwater was treated by Fe0 in large-volume, flow-through columns to monitor the changes in chemical and hydraulic parameters over time.
