Abstract:
PCT No. PCT/AU97/00603 Sec. 371 Date May 15, 1998 Sec. 102(e) Date May 15, 1998 PCT Filed Sep. 16, 1997 PCT Pub. No. WO98/12541 PCT Pub. Date Mar. 26, 1998A spectrophotometer including a light source (1) operative to emit a beam of light (15), an optical system for directing the light beam (15) to a sample (8) to be analyzed, and a detector (9) which detects the intensity of the light beam after the beam interacts with the sample (8). The light source (1) is operative to emit bursts of light separated by an interval during which no light is emitted. By way of example, a xenon tube may be used for that purpose. The spectrophotometer measures the intensity of the light beam generated by each burst of light after that beam interacts with the sample. Each such light beam may be divided into first and second parts (5 and 4) prior to interaction with the sample (8), and the optical system is arranged to direct the first part (5) to the sample (8) and to direct the second part (4) to a second detector (7) for conducting a reference measurement. A dark signal measurement may be conducted immediately before or after each burst of light.
