Coating Integrity Optical Inspection

A Scanning Electron Microscope (SEM) and/or an optical microscope with proper magnification is used to inspect the surface defects and coating integrity of the device before and after testing. Coating anomalies, defects or artefacts are located and documented.

A Spectroscopic Analysis is used to identify the chemical composition of particulate material to differentiate coating and delivery system particulates from those from other sources.

Test Procedure

The examination is performed on at least six locations from each sample. If required, a section of the sample is prepared using scissor or scalpel.

Equipment

High resolution scanning electronic microscope

ViVitro Labs Advantages

Many companies look to academia to handle their testing needs due to the reduced cost. With ViVitro Laboratory Services you gain the following advantages:

ISO 17025 Accredited
For studies used for regulatory approval this is a must. Victoria and Marseille labs accredited by A2LA.

Test Method Validation
The FDA and Notified Bodies around the world are requiring evidence of Test Method Validation. ViVitro Labs has invested significant resources to validate the most common test methods that are not ISO 17025 accredited. We continue to work closely with device manufacturers and share the burden with our clients to validate other specific test methods that are less in demand.

Timeliness
We understand how critical your timelines are. Our expertise and experience ensure your schedule is met and our commitments are delivered on time.

Free Initial Consultations
All of our studies are scoped via no-cost, no obligation, collaborative consultation.

Guaranteed Confidentiality
We happily provide Non-Disclosure Agreements for all services, including initial consultation.
