Abstract
A liquid sample analyzer includes a flow cell, a light source, and a lamp temperature management system. The flow cell is configured to receive a flow of a liquid sample from a liquid sample source. The light source includes a lamp configured to emit light to illuminate the flow of the liquid sample in the flow cell. The lamp temperature management system includes: an air flow generator operable to generate a turbulent air flow to cool the lamp; a thermally conductive primary housing encapsulating the lamp such that a primary air gap is provided between the primary housing and the lamp; and a thermally conductive secondary housing surrounding the primary housing and configured to deflect the turbulent air flow away from the primary housing.
