  • Page 5 Given that the absorption of a compound strictly depends on the wavelength of the incident light beam, a narrow spectral bandwidth should be selected as well as a proper central wavelength to optimize measurements. The optical system of Hanna's C 99 & C 200 multiparameter photometers is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

    TIPS FOR AN ACCURATE MEASUREMENT TIPS FOR AN ACCURATE MEASUREMENT TIPS FOR AN ACCURATE MEASUREMENT TIPS FOR AN ACCURATE MEASUREMENT TIPS FOR AN ACCURATE MEASUREMENT The instructions listed below should be carefully followed during testing to ensure best accuracy. • Color or suspended matter in large amounts may cause interfer- ence, therefore, these should be removed by treatment with active carbon and by prior filtration.
  • Page 11 • Proper use of the powder reagent packet: (a) use scissors to open the powder packet; (b) push the edges of the packet to form a spout; (c) pour out the content of the packet. • It is important that the sample does not contain any debris. This would corrupt the readings.
