Optimal technical solutions
for development of a spectrophotometric detector are discussed. A technique
for measuring absolute optical density in small diameter circular capillaries
is offered. To this end, a notion of light beam filling factors is introduced
and formulas for correction of experimental results are given. The calculations
and recommendations for estimation of these ratios from the experimental
data for various adjustments of the optical system are presented.
