Abstract
An apparatus for identifying analytes of a first type in a fluid sample having a plurality of types includes a closed flow cell. The flow cell includes a sample inlet, a sample outlet. A flow path, between the inlet and outlet, passing through an interrogation region and at least a portion extending from immediately upstream to immediately downstream of the interrogation region is bounded by a flow cell well to form a continuous closed flow path. The apparatus also includes a spherical element having a center point coincident with the interrogation region. A hydrodynamic focusing element upstream of the interrogation region creates a core-in-sheath flow along a flow axis of the flow path as it passes through the interrogation region. Further, the apparatus includes a concave, ellipsoidal collector element having a first focal point disposed in the interrogation region of the flow path. A plurality of beams of electromagnetic energy converge non-axisymmetrically at the interrogation region, each of the plurality of beams orthogonal to the flow axis.
