900 Laboratory TOC Analyser
900 Lab TOC Analyzer optimizes both specialized and general purpose TOC measurements and meets or exceeds the most common pharmaceutical and USEPA regulatory requirements in force today.
The Sievers 900 Laboratory Total Organic Carbon (TOC) Analyzer enhances productivity for laboratory TOC measurements. Automated calibration and validation procedures, fast analysis time, automated reagent adjustment, and the high-capacity 900 Autosampler combine for an unequalled level of efficiency, flexibility, and ease of use.
The 900 Laboratory Analyzer enables complete unattended operation with an Autoreagent feature that calculates and applies the appropriate reagent flow rate for any sample without requiring user intervention. The optional Autosampler, featuring random access capability and up to 120 sample positions, further enhances productivity.
The 900 Laboratory was engineered for ease of use and cost-effective operation. It needs no external reagents or gas supplies and typically requires only a few hours of preventive maintenance per year. Twelve-month calibration stability frees analysts to perform other critical tasks. A large, color touch-screen display provides an intuitive menu to quickly establish operating parameters. A space-saving 19.2-cm (7.6-in) wide profile efficiently uses valuable bench space.
The UV/persulfate oxidation method and patented Membrane Conductometric Detection Technology deliver unmatched accuracy and precision across the 900 Laboratory Analyzer’s 0.03 parts per billion (ppb) to 50 parts per million (ppm) operating range. The 900 Laboratory Analyzer optimizes both specialized and general purpose TOC measurements and meets or exceeds the most common pharmaceutical and USEPA regulatory requirements in force today. It is ideal for routine analysis of TOC samples, and is also well suited for testing laboratories that analyze a variety of sample matrices and concentrations.
