INDUSTRY LEADING ULTRA-TRACE COULOMETRIC O 2 ANALYZERS APPLICATIONS • Continuous quality control monitoring • Inert gas control checks for electronics-grade gases • Post-purifier quality certification • Leak detection for electronics grade gases PERFORMANCE Range: DF-550E: 0-20ppb to 0-10ppm DF-560E: 0-1ppb to 0-20ppm DF-550E DF-560E Lower Detection Limit: DF-550E: 200ppt DF-560E: 45ppt Accuracy: ±3% of reading / ±3% of measurement range or ±0.1ppb Zero drift/month: Negligible T90 in seconds: <15 at 0.7 liters/min KEY BENEFITS • Ultra-trace Coulometric sensing saves costs through low maintenance and long sensor life • Recovers quickly from process upsets and compensates for sample and flow rate fluctuations • Industry-leading LDL ensures the best available product purity • Just one analyzer required for O 2 measurements in a range of background gases • Portable option makes the DF-500 range easy to carry around Our DF-500 range of analyzers are verified by independent experts as measuring to the lowest parts-per-trillion (ppt) levels available, providing an ideal solution for the semiconductor industry. Designed to monitor ultra-high- purity (UHP) gases, they deliver the best Lower Detection Limits (LDL) currently attainable. Smart firmware virtually eliminates background noise, enhancing accuracy, while the Coulometric sensor needs minimal maintenance. The highly stable Coulometric sensor delivers a fast response which is unaffected by sample and flow rate changes. This ensures sensitive and reliable process monitoring for UHP electronic gases, even in upset- prone conditions. Two models are available – the DF-550E and DF-560E – each providing the same value-added benefits but optimized for different measurement ranges. The DF-550E measures O 2 from 0-20 parts per billion (ppb) to 0-10 parts per million (ppm), with a highly sensitive 200ppt LDL, while the DF-560E operates in the 0-1ppb to 0-20ppm range and supports the semiconductor sector with an industry-leading 45ppt LDL. The lightweight design also makes the analyzer ideal for semiconductor fabs and analytical carts. An annual span calibration is required, and there is no need for programmable cell replacement.
