Beschreibung
Zusammenfassung:	Disclosed herein is an apparatus comprising: a valve system configured to supply first and second samples of a solution successively to a single container, the first sample having a temperature which is different than that of the second sample; and a spectral analyzer configured to: make a first measurement of transmission of ultraviolet light at a selected wavelength through the first sample of the solution present in said container; make a second measurement of the transmission of ultraviolet light at said selected wavelength through the second sample of the solution present in said container; and determine a concentration of a halogen in the solution using the results of the first and the second measurements.
