Particle standard and calibration method

摘要: Apparatus and method for establishing an absolute particle calibration standard useful fluid contamination control like applications. A soluble carrier releasably secures a known number of size particles (microbeads) in geometric array, which serves as the reference standard. The may be selectively dissolved to release into system tested or calibrated. is manufactured by introducing solid size, within given range, precisely-dimensioned metering slot groove constrains predetermined desired array. Examination microscope other suitable means verifies count particles. geometry array facilitates visual counting. adherent medium applied arrayed particles, after adhered removed from transported integral set.
