摘要
In an analytical photometer, in particular multi-channel, for the simultaneous analysis of a multiplicity of samples, the light source provided is a flash tube for producing light pulses in which a permanent preionization discharge is maintained and the light energy is derived by optical fibres to be sent to optical systems where the beam is divided into an analysis beam which travels through the sample and a reference beam, both finally delivered to photodetectors. Both the divided beams pass through identical filtering systems for selection of a narrow spectral band of relevance for analytical purposes.
