The XHP-PFC-200 Fully Automatic Fatty Acid Value Analyzer employs potentiometric titration. Compared to the PFC-100 model—which relies on colorimetric determination—potentiometric titration offers significantly greater precision in identifying the titration endpoint and eliminates the need for chemical indicators.
· Built-in test methods for determining the fatty acid values of grains, wheat, and corn ensure convenient testing via a single-touch operation; results are displayed in mg KOH/100g of dry matter, with the instrument performing automatic conversions to eliminate the burden of manual calculation.
· Multiple self-diagnostic functions simplify the operational workflow and prevent errors caused by improper operation.
· Powerful application editing capabilities allow users to create and save custom titration protocols tailored to specific experiments, enabling instant recall with a single touch for future use.
· Features an integrated syringe pump housed within the instrument chassis; the pump's status can be monitored externally through a viewing window. This design completely isolates the operator from the reagent flow during analysis, preventing potential injury caused by spills or splashes.
· Utilizes an imported composite electrode as the endpoint sensor, ensuring a longer service life.
· Displays the titration curve in real-time, providing a visual representation of the entire titration process.
· Can be equipped with a 16-position automatic sampler to enable automated batch analysis, thereby significantly boosting operational efficiency.
· Employs advanced AI algorithms to control the titration process, determining the precise titration endpoint based on a fitted curve analysis.
