carbon in water?
total organic carbon volatile organic carbon total carbon Dohrmann's DC-50 organic analyzer makes all of these measurements accurately and rapidly. Based on proven methods, it avoids interferences and undesirable pyrolysis reactions that historically have resulted in significant errors. Here's why the DC-50 is the complete solution for the analysis of carbon in water: D I R E C T READOUT. Four-digit presentation shows carbon content directly in mg/liter or ppm. No recorder needed.' D I R E C T M E A S U R E M E N T . A single sample injection gives either Organic Carbon or Total Carbon content directly, not by difference. INDEPENDENT MEASUREMENT. Volatile Organics are determined separately from Total Organics to aid in source identification. RELIABLE M E A S U R E M E N T S . Determines important, lightweight volatiles such as low molecular weight alcohols and ketones, normally lost by acidification and sparging. FAST: 5 minutes per determination A C C U R A T E : repeatability of ± 1 m g / liter or ± 2r/< W I D E R A N G E : 1 to 2,000 mg/liter (ppm) without dilution P R I C E : $7,500, including start-up assistance and operator training EPA EVALUATED: Newsletter #15 Oct. 1972 AQCL, N E R C , E P A Cincinnati, Ohio 45268 Contact: D O H R M A N N Division, Envirotech Corporation, 1062 Linda Vista Ave. Mountain View, CA 94040 (415) 968-9710

U.S. Instrumentation Exhibition in Sweden The U.S. Department of Commerce will sponsor an exhibition of Instruments for Physical/Chemical Measurement, March 11-15, 1974, at the U.S. Trade Center for Scandinavia in Stockholm, Sweden. Marketing surveys show an increased demand for advanced instruments in Scandinavian instruments. Among the instruments with high sales potential are test instruments, gas chromatographs, ultraviolet spectrophotometers, mass spectrographs, densitometers, refractometers, spectrometers, and electronic data processing equipment. This will be the 69th specialized trade show held at the Center which was established in 1965 to help U.S. manufacturers increase their sales in Nordic markets. For more information, contact Edward Leslie, Country Specialist, DIBA-224, U.S. Dept. of Commerce, Washington, D.C. 20230. 202-967-4461
