This document provides an overview of extractables and leachables (E&Ls) studies. It discusses that E&Ls studies are needed in industries like biomedical devices, food packaging, and pharmaceutical packaging to identify substances that can migrate from materials into products. Jordi Labs is introduced as a leader in E&Ls analysis with state-of-the-art facilities and over 80% of staff being chemists. The document outlines the basic process of an E&L study including sample selection, extractions, identification of E&Ls using techniques like mass spectrometry, quantitative analysis, and determining acceptable levels. Regulations for E&Ls from organizations like USP, FDA and ISO are also summarized.
