IHPAT Diffusive Samplers Update
IHPAT Diffusive Samplers Sample Generation Method Change
PAT Programs is reminding participants that IHPAT Diffusive Samplers sample generation method has been updated. These samples will now be produced using a vapor deposition method. Following a successful pilot of the newly developed samples, the pilot data was provided to the PAT Board in March of this year and was approved later in that month. The PAT Programs would like to thank those organizations that participated in the Vapor Deposition Pilots.
These mass-generated samples are closer to what may be submitted to your organization by a client. In addition, the benefits of this change are:
- Vapor deposition will eliminate the usage of acetone as a liquid spiking solvent. This change should return your curves to what is expected for the analyte.
