Abstract: A chemiluminescence analyzer determines the level of chemiluminescence of a specimen. The chemiluminescence analyzer includes a light detection chamber for containing the specimen to be analyzed. The light detection chamber includes a chamber access device, for allowing the positioning of the specimen within the light detection chamber, and a shutter device. The shutter device and the chamber access device are configured to each have an open position and a closed position. A light detector is positioned behind the shutter device. When the shutter device is in the open position, the light detector detects light within the light detection chamber. An interlock assembly is interfaced with the shutter device and the chamber access device, such that the interlock assembly prevents the shutter device and the chamber access device from being simultaneously opened.

Abstract: An oxygen sensor contains an indicator whose change in absorption is a function of the concentration of oxygen in a sample bathing the indicator. Light transmitted and reflected through the indicator of the sensor undergoes an absorption that is characteristic of the concentration of oxygen. The indicator is a viologen whose absorption returns to a steady-state value after it has been subjected to a pulse of short-wavelength light. The rate at which the absorption returns to the steady-state value is a function of the concentration of oxygen bathing the viologen indicator. A measurement system for use with the pO.sub.2 sensor causes a short-wavelength flash to be sent to the sensor and thereafter monitors the time-varying absorption of the sensor to measure the oxygen content of the sample bathing the viologen indicator.
