CuDDI - Copper Digital Detection Imaging

Copper corrosivity has become a critical indicator of sulfur compounds present after the refining process. Measuring corrosivity continues to be a challenge, as no accurate standardized test has been developed to date. Current corrosivity tests involve manual and visual assessments, resulting in human error and bias. The petroleum industry calls for a high-level, high-tech standard for copper detection.

The new Copper Digital Detection Imaging (CuDDI) instrument from Ayalytical Instruments, Inc. identifies exact levels of corrosivity present from petroleum through a 4-step automated vision algorithm and classification process, eliminating operator bias. Results are digitally recorded and are seamlessly integrated with LIMS software.

Principle

CuDDI’s exclusive, patent pending design takes the guesswork out of copper corrosion detection. Its unique vision algorithm and light box records, calculates and displays accurate corrosivity ratings in a matter of seconds. A high-resolution camera with sophisticated optics provides higher precision machining and motors for the rotation of the copper strip. The results are not only a groundbreaking improvement on the rating, methodology and sample handling of current laboratory procedures; they are the new standard for copper detection.

The CuDDI Method

Copper digital detection imaging is a simplified process requiring minimal steps that effect maximum efficiency:

Step 1: Insert strip into specialized holder
Step 2: Place holder into instrument
Step 3: LED light source is automatically activated and regulated
Step 4: Software identifies first position and captures first image
Step 5: Software then rotates the holder 180 degrees and captures second image
Step 6: Readings are tabulated and processed through CuDDI algorithm
Step 7: Final results are displayed on a high-resolution touch screen

Final Results are Clear, Concise and Cutting-Edge.
