Abstract
Aspects and embodiments of the instant disclosure provide a particle and/or intracellular organelle alignment agent for a particle analyzer used to analyze particles contained in a sample. An exemplary particle and/or intracellular organelle alignment agent includes an aqueous solution, a viscosity modifier, and/or a buffer. Embodiments also encompass systems, compositions, and methods for analyzing a sample containing particles. Particles such as blood cells can be categorized and counted by a digital image processor. A digital microscope camera can be directed, for example using certain focusing techniques, into a flowcell defining a symmetrically narrowing flowpath in which the sample stream flows in a ribbon flattened by flow and viscosity parameters between layers of sheath fluid. Blood cell images can be collected and analyzed using dynamic range extension processes and systems.
