1 ANALYSIS OF TOOL COMPONENTS BY. ULTRASONIC EXTRACTION AND. LIQUID PARTICLE COUNTER (LPC). What is UPW ULTRASONIC Extraction LPC? ULTRASONIC energy extracts both surface and partially embedded particles from tool component surfaces into ultrapure water. Subsequent ANALYSIS of the extract by Laser Particle Counter yields results at 5 standard ranges of particles m, m, m, m and m. 1 3. STEP 1 STEP 3.

ULTRASONIC technology is a proven method for extracting particles from the surface of parts in a liquid medium ULTRASONIC waves produced by transducers penetrate deeply and evenly across intricate part geometries and into crevices and blind holes, colliding with and disintegrating contaminants on the surface of the part These contaminants are suspended in deionized water and subsequently analyzed with a liquid particle counter Test methodology based on ULTRASONIC extraction is required since part was first cleaned ultrasonically. Test methodology cannot be less powerful than the cleaning protocol employed ACCURACY. Accuracy is evaluated using ready-to-use certified particle standards manufactured by Clintex particles are polystyrene standard spheres with m diameter Units in particles /mL.
