The Sievers 900 Portable TOC Analyzer, weighing only 12.5 kg and measuring 35.6 x 22.3 x 46.5 cm, is the first portable TOC analyzer of its kind, bringing the lab to the field. It can be hand-carried anywhere for on-line measurement, used for grab samples, or connected to an autosampler for high volume applications in a laboratory. It requires no external reagents or gas supplies and boasts a four-minute analysis time and a 0.03 to 50 ppb measurement range. The Sievers 900 Portable's color touch-screen display provides an intuitive menu to quickly establish operating parameters, such as setup and automated calibration procedures, and to graph historical or real-time data. A USB drive enables easy data transfer. The Analyzer was engineered for ease of use and cost-effective operation, requiring no external reagents or gas supplies. It typically needs only a few hours of preventive maintenance annually. The Sievers 900 Portable won Instrument Business Outlook's 2005 Gold Award for Best Portable Analytical Instrument Industrial Design.
