The Hyperflux Velocimeter Story
Operating the Hyperflux Velocimeter
A small sample of particles or cells suspended in a liquid (Figure 1) enters the unique stopped-flow sample cell (Figure 2). These are the components of the integrated, user-friendly Hyperflux Velocimeter (Figure 3) with its unique long-working-distance dark-field microscope and special magnetic gradient that propels particles or cells at constant velocity in the stopped-flow sample cell. All operations are controlled by software.
The histograms and plots are smooth, because the Hyperflux Velocimeter analyzes some 50,000 events in a typical measurement. This is achieved by three unique software packages consisting of:
IKOVision is a real time image capturing microscope which serves as the backbone of the data acquisition phase of the Hyperflux process. A sophisticated high resolution camera is calibrated to the needs of each experiment, capturing motion images of the target material for data analysis. Any number of experimental runs can be produced during this process, each with varying magnification and frame rate options, allowing for sophisticated data analysis.
Cytotest is the data processing arm of the Hyperflux process. Experiments captured by IKOVision are processed by Cytotest’s sophisticated image processing engine to produce high-quality particle tracking data sets. Operator selected gating parameters enable a high-quality culling process to be applied to the experimental data using pre-set limits or taking advantage of the unique capabilities of the human eye. Once particle selection is complete, the tracking process traces each particle over the duration of the stored video record and outputs a CSV formatted data set for analysis by Magex or for export to other analysis packages.
Magex is a sophisticated data analysis tool made available at no additional charge to Hyperflux customers. Track by track and frame by frame analysis of all Cytotest produced data enable the operator to directly observe particle movement through the re-played experimental run (Figure 5). Per frame fluidic particle measurements include Average, Median & Standard Deviations for many particle properties, and direct particle tracking enables determination of additional information such as sedimentation rate, track linearity and cell size-related properties.
