CAT NO: DIDACTICNLE-Export-132003
Designed for use in routine or research work
in various application-medicine, Agriculture, Industry and others. An
accurate and sensitive instrument, it can be operated without special
skill of training. Fluorescence is basically the instantaneous emmission
of light from a molecule ( or atom) which has absorbed light. When a
solution containing has molecules of interest is irradiated with light
of a selected wavelength. The radiation is given off at all angles but
is usually collected at right angles to the primary light beam to reduce
the efforts of scatter from the sample. This energy is passed through a
narrow bandpass filter and allowed to fall on a sensitive
photodetector. The electrical output of the photodetector is amplified
and fed into a moving coil meter. Calibration is performed on
a comparative basis against standards of known concentration, (Details
