DiscovIR-GC
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.
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.
- Micro-Deposition on Cryogenically-Cooled IR-transparent disc
- Solid phase transmission FTIR spectra with high resolution
- Runs stand-alone or in parallel with GC-MS
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.

DiscovIR-LC
DiscovIR’s unique temperature controlled, vacuum deposition method ensures that results are accurate and reproducible. Eluted peaks are first deposited in a film on to a rotating IR transparent disc. Next, an infrared beam passes through each concentrated spot and the detector automatically collects spectral data.
Cryogenic temperature control of the Sample Disc minimizes the area of the deposited analyte. This results in a thicker sample layer and therefore Higher Sensitivity of the absorbance spectrum.

Revolutionary Desolvation Technologyenables total flexibility with mobile phase solvents for GPC-FTIR. Solid phase transmission FTIR Spectra free from solvent interference are acquired continuously during the chromatography. The system is fully automated and compatible with autosamplers.
Complete solvent removal combined with controlled temperature cryogenic deposition minimizes band spreading and maintains the chromatographic resolution.
