The PFC-100 Fully Automatic Fatty Acid Analyzer is a critical instrument designed for assessing grain storage quality deterioration based on fatty acid values. It resolves the practical issues associated with using phenolphthalein indicators to determine the titration endpoint—specifically, the difficulty in observing the endpoint, the inaccuracy of results, and poor comparability. Utilizing potentiometric titration technology, the device features built-in, specialized test protocols for determining the fatty acid values of various grains—including wheat and corn—thereby ensuring significantly more accurate measurements.
l Incorporates built-in test methods for determining the fatty acid values of grains, wheat, and corn, making testing more convenient with one-touch operation; results are displayed in mg KOH/100g of dry matter, with the instrument performing automatic conversions to eliminate the hassle of manual calculation.
l Features multiple self-diagnostic functions to simplify the operational process and prevent user errors.
l Offers powerful application editing capabilities, allowing users to create and save custom titration modes tailored to specific experiments, which can then be instantly recalled with a single touch for future use.
l Features an integrated burette design—housed entirely within the instrument—allowing users to monitor the titration process externally through a viewing window; this ensures complete physical separation between the operator and the solution during operation, thereby preventing potential injury caused by spills or splashes.
l Utilizes a high-resolution camera to capture images for precise determination of the titration endpoint, while simultaneously displaying the real-time progress of the titration.
l Offers multi-level adjustable titration speeds to accommodate the analysis of various sample types.
l Includes a built-in magnetic stirrer that operates concurrently with the titration process, featuring an adjustable stirring speed.
l Features a visual design for the syringe pump mechanism, facilitating easy observation of the titration status.
l The software interface provides a real-time visual display of the titration process and automatically plots the corresponding titration curve.
