ASD pioneered the science of field spectroscopy over 25 years ago and continues to lead the industry with the world’s most trusted field-portable UV/Vis/NIR/SWIR spectroradiometers covering the full solar reflected spectrum.

The ASD FieldSpec 4 line of full-range spectroradiometers delivers the fastest and most accurate spectral field measurements available from any commercial field-portable spectroradiometer. Continued enhancements to core instrument spectrometers and other critical components have dramatically improved overall performance, signal, and integration speeds compared to earlier models.

ASD FieldSpec 4 spectroradiometers are designed specifically around the challenges researchers face when collecting spectral measurements in the field.

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. 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.

Drug exhibits have become more challenging over the years due to an increase in complex synthetic substances with many positional isomer and diastereomer possibilities. With the DiscovIR-GC® from Spectra Analysis Instruments, forensic and law enforcement labs can now easily and rapidly identify designer drugs, by-products, and cutting agents with a higher level of specificity and discrimination which is unattainable through mass spectrometry alone.
