Solid-Phase Infrared Detector (DiscovIR-GC)

Molecular and Isomeric Identification for Gas Chromatography
The DiscovIR-GC is an analytical infrared instrument that combines the separating power of the Gas Chromatograph with the molecular identification of FTIR. DiscovIR’s unique temperature controlled, vacuum deposition method ensures that results are accurate and reproducible. Eluted peaks are first deposited in a film onto a rotating IR-transparent disc. The disk rotates the concentrated spot into the infrared beam and the spectrum is collected. The DiscovIR-GC provides structural and positional information to help the MSD resolve your isomeric challenges.

Boost efficiency of your current compound ID
The new Spectra Analysis DiscovIR System is the perfect solution when identifying the components in a complex mixture. Infrared spectroscopy provides each compound’s unique fingerprint, making it quick and easy to identify each peak by comparison to the extensive solid phase IR libraries. The DiscovIR system is particularly useful in identifying structural isomers, which can be a challenging area for Mass Spectrometry.

Micro-Deposition Improves Analysis
DiscovIR’s unique temperature controlled, vacuum deposition method ensures that results are accurate and reproducible. 

Concentrates Analytes in Minimal Area
Cryogenic temperature control of the Sample Disc minimizes the area of the deposited analyte. This produces a thicker sample layer and therefore higher sensitivity of the absorbance spectrum, generating a practical result where gas phase detectors deliver little useful information.

Retains Entire Chromatographic Run
The entire chromatographic run is applied as a solid deposit on the Sample Disc, preserving the resolution of the separation, therefore, the entire run is available to be scanned again in order to investigate subtle features and improve signal-to-noise. The speed of the rotating Sample Disc can be adjusted to match concentration of the deposited sample.
