Liquid Particle Counting (LPC)
The particle contamination of the part to be controlled is extracted with DI water (18 Mohms, filtered at 0,2 µm + ultrasonics, shaking table, …).
A sample of the extracted solution is analyzed with a LPC counting system. The difference between the number of particles from the blank solution and the extracted solution indicates the level of cleanliness of the product.
Analysis by SEM-EDX
Packaging sealing validation
Tracking of a specific contaminant
Prove that a specific contaminant is no more present on the product after the cleaning process. This method is similar to the tracking of surfactant trace after detection of the type of tracer of he contaminant: ionic, metallic, organic,…
Non Volatile organic residue control
Sterility test of solutions
Sterility test of « Ready To Use » solutions, according to chapter 2.6.1 of the European Pharmacopeia.
