©2026 Biological and Chemical Oceanography Data Management Office.Particle size analysis, particle size measurement, or simply particle sizing is the collective name of the technical procedures, or laboratory techniques which determines the size range, and/or the average, or mean size of the particles in a powder or liquid sample.

|---|---|---|
| Bulk and AA d15N values for ala, glu, and phe from phytoplantkon and grazers grown in lab chemostats | The reactors were monitored daily for 12-15 days to ensure constant conditions, thus minimizing predator: prey isotopic mismatch, and samples were taken for cell abundances and biovolumes using an Elzone counter and epifluorescence microscopy. | Elzone counter |
| EV and Viral-Like Particle Abundances and Size Distributions by NTA from CTD Water Samples on R/V Atlantis Cruise AT50-08 | The ZetaView Evolution system was used for nanoparticle tracking analysis (NTA) to quantify particle size distributions and concentrations based on Brownian motion tracking in a video microscopy platform. The instrument supports measurement of particle concentration (typically 10⁵–10⁹ particles mL⁻¹), size distributions over an approximate range of 10–1000 nm (depending on sample and optical configuration), and zeta potential (−500 to +500 mV) across a pH range of 1–13. The system includes fluorescence NTA (F-NTA) capabilities with up to four excitation lasers and multiple detection channels, enabling detection of labeled particle subpopulations with sensitivity below ~20 AF488-equivalent fluorophores. Available excitation wavelengths include 405, 488, 520, 640, and 660 nm. The instrument also supports colocalization NTA (C-NTA), allowing simultaneous detection of two fluorophores on individual particles, which is particularly useful for characterizing heterogeneous EV and viral populations in complex environmental samples. | ZetaView Evolution Nanoparticle Tracking Analyzer (Particle Metrix, Germany) |
