PHOTOchem PHOTOchem offers a major improvement in low level organic carbon determinations. Because it utilizes photochemical (ultraviolet) oxidation combined with a unique and highly sensitive detection system. PHOTOchem is the only low level analyzer able to offer an automatic sample introduction system that provides unattended measurement of up to 90 samples in a 24-hour period. And TOC determinations are precise and accurate (and free of interference from
inorganic carbon) in an analytical range of 20.000 ppm down to 50 ppb and lower!
PHOTOchem has very few moving parts, which means greater reliability and lower purchase and operating costs. And, should the need arise for on-site use. PHOTOchem is easily transportable. For complete information or a demonstration, call or write Barnstead Company. Division of Sybron Corporation. 225 Rivermoor Street. Boston, Mass. 02132. Telephone (617) 327-1600.
The photochemical oxidation process eliminates sparging, sample boats, ovens, combustion gasses, graph interpretation and, most importantly, the operational complexity found in conventional equipment. Both volatile and non-volatile organic components are measured simultaneously, without special procedures or auxiliary modules.
