Halo Labs HORIZON® is a membrane-based particle analysis system designed for fast, reliable particle characterisation using advanced image processing. The system first captures a background image of the membrane, then re-images the same membrane after vacuum filtration has captured particles. The sample image is precisely aligned to the background and processed pixel-by-pixel to eliminate membrane texture, producing high-contrast particle images with strong reproducibility and minimal interference from membrane imperfections.

The HORIZON® platform is supplied with VUE software, an intuitive analysis suite that provides automated particle characterisation outputs including Equivalent Circular Diameter (ECD), aspect ratio, circularity, and more. Individual particle images can be reviewed, and interactive scatter plots and histograms support rapid visualisation of size distribution, variability, and other key statistics. :contentReference[oaicite:1]{index=1}

This Halo Labs application note (Rev C, 2020) describes a straightforward verification procedure for particle sizing accuracy on the HORIZON® system using certified, ready-to-use microsphere standards traceable to the National Institute of Standards and Technology (NIST). The note recommends Thermo Fisher COUNT-CAL™ polystyrene bead standards (precise sizes spanning 5–30 µm, with a tight size distribution specification of <3%) and outlines storage and handling guidance (store at 2–8°C, never frozen, mix by gentle inversion).

Key workflow steps described in the note:

• Select and prepare the NIST-traceable size standard.
• Configure VUE software settings for sizing verification (use the “HaloLabs Recommended” particle detection profile and set appropriate custom size bins; use cumulative bins for reporting).
• Acquire background images, load samples onto the HORIZON® plate, and perform measurement.
• Analyse singlet beads only (exclude aggregates via bin selection) and calculate an average singlet size from the median particle and its two neighbours.

Case study results reported in the note (8 wells per bead size) showed sizing within 2.2% of the vendor-certified specifications. Reported examples:

• 5 µm standard: certified diameter 5.01 µm (SD 0.04); HORIZON® measured ECD average 4.9 µm (SD 0.06)
• 10 µm standard: certified diameter 10.0 µm (SD 0.08); HORIZON® measured ECD average 10.0 µm (SD 0.15)
• 15 µm standard: certified diameter 15.02 µm (SD 0.15); HORIZON® measured ECD average 15.0 µm (SD 0.12)
• 30 µm standard: certified diameter 29.75 µm (SD 0.56); HORIZON® measured ECD average 29.4 µm (SD 0.28)
