Frequently Asked Question
1: How does the RGB titration system improve endpoint accuracy in complex matrices?
The Automatic Kjeldahl Analyzer FM-KA-B101 uses coaxial R/G/B detection to auto-adjust for color shifts, reducing false endpoints in turbid, pigmented, or high-protein samples.
2: What role does titration resolution (0.2 µL/step) play in result precision?
The FM-KA-B101 delivers ultra-fine reagent dosing, essential for precise endpoint control in low-nitrogen or high-accuracy applications.
3: How does this analyzer support traceability in GLP-compliant environments?
The FM-KA-B101 ensures compliance through user-level access control, electronic logs, and secure internal data storage aligned with ISO/GLP standards.
4: In what conditions is adjustable titration speed (0.05 to 1.0 mL/s) functionally useful?
The FM-KA-B101 allows speed tuning—slower for reactive/foaming samples, faster for high-throughput workflows, balancing precision and efficiency.
5: What mechanisms ensure stable performance in high-throughput operations?
Equipped with integrated cooling, safety alarms, and auto shutdown, the FM-KA-B101 maintains consistent performance during long, unattended operation cycles.
