On the safe side: Contact-free analysis of chemical substances
Date:4/16/2012

the adjoining spectral ranges: high penetration depth and low scatter, accompanied by good spatial resolution and the capability of spectral identification of unknown substances.

Like radiation in the infrared range, Terahertz waves reveal a substance's spectral signature. The measurement device features a database with the spectral fingerprints" of hazardous materials and can be extended to include additional materials at any time. The device compares the spectral fingerprint of the substance to analyze with values in its database and returns a clear result. The scanner operates using transmission and reflection analysis. In safety checks, the terahertz wave offers low-loss penetration of envelopes made of paper or plastic to detect any chemical substances within. If a package contains, say, metal as housing for an explosive device the wave is reflected and measured by the receiver. This is how suspicious packages can be identified quickly.

Now the researchers also want to gain a foothold in the pharmaceuticals and chemicals industries. Up until now, makers of pharmaceuticals had to prepare extra samples if they wanted to find out whether the mixture ratio in a particular drug was right, whether the chemical was in the desired crystalline structure, and whether quality was all right," Jonuscheit points out. Depending on the substance and the material involved, our device clearly detects all of the chemicals found. It also provides basic analysis of the mixture ratio of multiple substances. Terahertz analysis also allows conclusions about the substances' crystalline structure. For instance, you can determine whether a potentially unwanted recrystallization has taken place. In the future, this can spare chemicals and pharmaceuticals manufacturers painstaking preliminary analysis and sample preparation," the expert points out.
