Abstract

A simple method for sampling photocopy toners by thermal transfer to metallic stubs is described. The sampling causes only negligible destruction to the photocopy original. The toner material transferred to a metallic stub is analyzed by microreflectance FTIR. This method shows a good reproducibility, is sensitive and applicable to small areas on the transferred material.
