Workplace air. Analysis of respirable crystalline silica by Fourier-Transform Infrared spectroscopy has-tracked-changes These requirements are not written1 Scope This document is a standard for the analysis by Fourier Transform Infrared (FTIR) of respirable crystalline silica (RCS) in samples of air collected on collection substrates (i. e. filters or foams). Three analytical approaches are described for whom the dust from the sample collection substrate is a) analysed directly on sampled filter, b) recovered, treated and deposited onto another filter for analysis, or c) recovered, treated and pressed
