Features


  • Non-Invasive Diagnostics: The Nephrolux® Human Breath Ammonia Analyzer offers a non-invasive approach to diagnosing kidney disorders by measuring ammonia concentration in exhaled breath.

  • Rapid Results: Provides results in approximately 2 minutes, significantly faster than traditional blood tests which can take 24-48 hours.

  • High Sensitivity: Minimum detectivity of 1 ppb (parts-per-billion) ensures precise measurements.

  • Continuous or Single Measurement: Offers flexibility with continuous monitoring or single-shot measurement cycles.

  • Direct Measurement: Measures ammonia directly without the need for preconcentration or conversion, ensuring accuracy.

  • Autonomous Operation: Functions without the need for operator intervention, simplifying the process.

  • High Selectivity: No interference from other ammonium-containing compounds, hydrocarbons, hydrogen sulfide, sulfur dioxide, water, or NOX.

  • Linearity and Accuracy: ±10% linearity over the measurement range with an accuracy of ±1 ppb or ±10% of the reading.

  • Precision and Zero Drift: Precision of ±1 ppb or ±10% of the reading, with zero drift of ±1 ppb per week.

  • Reliable Control Processor: Equipped with a Pentium class microcomputer and LINUX-based operating system for high reliability.

  • Robust Data Storage: Solid-state memory ensures crash-proof reliability with a user data storage capacity of over 1 year, extendable to over 4 years with Option EDS.

  • Intuitive Data Display: Features a touch screen display showing the last measurement for easy data access.

Applications


  • Noninvasive Diagnostics of Kidney Disorders: The Nephrolux® sensor measures ammonia in exhaled breath, correlating with blood urea nitrogen and creatinine levels, offering a noninvasive alternative to traditional blood tests.

  • Dialysis Treatment Monitoring: Allows frequent, real-time testing during dialysis sessions to ensure adequate treatment by measuring blood urea nitrogen and creatinine clearance.

  • Abnormal Pregnancy Monitoring: Potential application in monitoring breath ammonia concentration to provide early warnings of conditions such as preeclampsia.

  • Continuous or Single Shot Measurement: Offers flexibility in measurement cycles, with a direct measurement process that requires no preconcentration or conversion.

  • Autonomous Operation: The analyzer operates without requiring operator attention, enhancing ease of use.

  • High Selectivity and Accuracy: No interference from other compounds, with a linearity of ±10% and accuracy of ±1 ppb or ±10% of the reading.

  • Reliable Data Storage and Display: Features solid-state memory for crash-proof reliability, with user data storage for over 1 year, extendable to over 4 years. Includes a touch screen display for immediate data access.

  • Precision and Stability: Offers precision of ±1 ppb or ±10% of the reading, with zero drift of ±1 ppb per week.

  • Advanced Control Processor: Embedded Pentium class microcomputer running on a LINUX-based operating system for high reliability.
