WebStandards include: ASTM E168, E1252. If the material does not absorb infrared light a spectral scan cannot be obtained. Example: metals do not absorb infrared light. FTIR is the first logical step in identifying a polymer. FTIR is also used for quality control of materials and for contamination analysis (surface or internal). Test Procedure: A ... WebFTIR spectroscopy is a powerful tool for analysis of HCl at subppm levels. There have - been many comparison tests to FTIR with wet chemical methods such as EPA Method 26 and 26A for HCl analysis. FTIR has also been described as a CEM by Performance Specification 15(PS-15) and as a primary method when performing RATA analysis.
