Ftir Reference Standards. Materials are pretty much anything from vitamins minerals sugars and peptone. Ftir is the first logical step in identifying a polymer.
The ftir is an aglient cary 630 with an atr. The clean air act amendments caaa was published in november 1990. If the material does not absorb infrared light a spectral scan cannot be obtained.
Usp standards for drug reference standards are used to demonstrate identity strength purity and quality for medicines dietary supplements and food ingredients.
If the material does not absorb infrared light a spectral scan cannot be obtained. The ir spectrum table is a chart for use during infrared spectroscopy the table lists ir spectroscopy frequency ranges appearance of the vibration and absorptions for functional groups. The range covered is 4000 to 2000 cm 1. The traceability documentation included shows transmission values at seven band assignments.
