TOC-L laboratory total organic carbon analyzers from Shimadzu Scientific Instruments are suitable for analyzing ultrapure to highly contaminated samples of wastewater, brine water and drinking water. In PC-controlled and stand-alone versions, they have a sample range of 4 μg/L to 30,000 mg/L and use the 680 degree C combustion catalytic oxidation method. They have automatic sample acidification and sparging and automatic dilution that reduces sample salinity, acidity and alkalinity. They can be combined with the SSM-5000 solid sample combustion unit to analyze large particles, solids, soils and sludge. 800/477-1227; www.ssi.shimadzu.com.
