AE—Automation and Emerging Technologies: Design Modifications to a Remote Biological and Chemical Luminescence Analyser

Initially employed for clinical analysis, the biological and chemical luminescence application was extended to food, agriculture, veterinary medicine and the environment. Several authors have described the use of optical fibres as optical transducers connected to the light detector of a luminometer within the context of bio-sensor development. This paper seeks to improve remote biological and chemical luminescence analyser design by evaluating remote versus local mode when modifying light collection and transmission. In spite of specific design, light losses were high, with a transmission of only approximately 20%. Further improvements are feasible: straight alignment of the optical fibre bundle without a mirror could reduce light losses, and an integration time increase could compensate for them.
