Qualifying a Sonicator Bath for Sample Preparation
By Rachel Kohn |
In the pharmaceutical, cosmetic and food processing industries ultrasonic cleaners are employed as sonicator baths for sample preparation for analytical testing. Unlike cleaning medical devices, when using an ultrasonic bath to prepare samples,the analytical method that uses ultrasound is validated, not the equipment. Guidelines include ICH Q2(R1), procedures for validating analytical methods, and USP 1225, validating…
