FTIR spectral imaging applications in trace evidence

WebAn open path multiple reflection system with a 1 km optical path over a physical path of 25 m was constructed and adapted to a medium resolution FTIR spectrometer. The system can detect mixing ratios down to 10-9 for specific atmospheric constituents for trace gas emission monitoring. WebTo use an IR spectrum table, first find the frequency or compound in the first column, depending on which type of chart you are using. Then find the corresponding values for absorption, appearance and other attributes. The value for absorption is usually in cm -1. Note that not all frequencies have a related compound. the view today\u0027s episode youtube
