The analysis to detect any possible traces of chromium on leather, in compliance with ISO 17075 standard, may bring to false positive results. Their occurrence depends on several factors, such as determination process (colorimetric or chromatographic), extraction conditions (PH, dosing quantities, or, for example, matrix effect) and sampling methods. They are going to talk about such topics during a workshop: “False positive results in the leather analysis: issues and possible solutions”. The meeting, scheduled today, Thursday 3rd October, during Lineapelle97, will take place at the LEM conference room, located on the Ponte dei Mari (side hall 22, Fieramilano Rho), from 2.30pm to 4.30pm.
During the workshop, they will make public the results of two separate research projects. The former was carried out by University of Northampton, the latter by University of Insubria. Will Wise, Research Leader at the Institute for Creative Leather Technologies (ICLT), from the British university, and Sandro Recchia, Professor of Analytical Chemistry in the Lombard academy, are going to present their own research studies. While reviewing the colorimetric method and the chromatographic one respectively, they eventually reached very similar results.
Elisabetta Scaglia, environment and specifications specialist at UNIC- Italian Tanneries, and Fabiana Orlandi, CSR, sustainability and product safety specialist at the same association, will also join the panel of speakers. In the leather industry, analytical method reliability is a topical issue indeed, also considering REACH related prospective restrictions on sensitizing substances.
