title: Practical aspects of quantitative microphotometer system.
abstract: The parameters, characteristics and modifications of standard equipment, also operational methods, are discussed in the context of reading errors. The principal errors are identified: photocell and lamp filament temperatures--internally scattered light--sample position and orientation. The application of the instrument to a specific problem (corrosion of dental amalgam) is illustrated.
