VCD extends the functionality of electronic Circular Dichroism (CD) into the infrared spectral region where vibrational transitions in molecules are observed. The ChiralIR is the first selling VCD instrument. The second generation is equipped with all digital processing and an upgrade to revolutionary DualPEM set-up a plug-and-play, without bulky electronics.
