The Thermo Scientific™ Nicolet™ iS20 FTIR Spectrometer maximizes productivity in the lab and enables the rapid collection of high-quality spectral data. A built-in touch panel allows users to quickly inspect difficult samples. A new multi-color LED scan bar informs users whether the instrument is in idle, collect, or alert mode. Attach the Thermo Scientific™ Nicolet™ iN5 IR Microscope to this FTIR spectrometer, and you now have an ideal tool for visually locating and identifying unknown contaminants present in prepared samples from environmental, food, and biological sources.    

Built with the  Thermo Scientific™ LightDrive™ Optical Engine, the Nicolet iS20 Spectrometer  can accurately determine unknown contaminants with higher spectral resolution than the previous generation. Confidently perform product failure analysis, advanced quality control, and precisely analyze mixtures using its powerful spectral analysis software. A 10-year warranty on the interferometer, source, and laser offers unparalleled peace of mind for a decade to come.


The Nicolet iS10 FTIR Spectrometer sets the standard for analytical FTIR instruments and is trusted by users around the world. The next-generation Nicolet iS20 FTIR Spectrometer currently pushes the limits of innovation to new heights with its re-engineered optical engine and modern industrial design. The Nicolet iS20 spectrometer offers the ideal combination of the Nicolet FTIR platform to users with modern improvements.

Accurately distinguish multi-component samples: Advanced LightDrive optical engine technology offers higher spectral resolution (0.25 cm-1) and signal-to-noise ratios (50,000:1) to help classify possible contaminants or identify the root cause of defects.

Enhance data reproducibility: Advanced infrared source eliminates hot-spot migration, leading to more dependable spectral data, especially via an attenuated total reflectance (ATR) accessory.

Simplify workflow productivity: Multi-colored LED touch panel provides visual feedback on status of the instrument for improved productivity (ready, scan, alert); System Performance Verification (SPV) ensures daily results are reliable. The integrated touch panel can be used to quickly implement SOPs.

Decrease cost of ownership: The 10-year warranty on the interferometer, source, and laser minimizes downtime; the LightDrive interferometer provides a five-fold increase in relative lifetime over current interferometer technology, decreasing the need for replacements.

Share data anytime, anywhere: By using this  cloud-enabled FTIR spectrometer, data can be uploaded to the Thermo Fisher Cloud. Students can upload, analyze, and share data away from the instrument using the OMNIC Anywhere App on their Apple Computer, PC, Android, or iOS device. All Thermo Fisher Cloud accounts are offered with 1 terabyte of free storage.

Be compliant, be sure: Totally automated validation test routines are available for IQ/OQ (installation and operational qualification), United States Pharmacopeia (USP), Japanese Pharmacopeia (JP), European Pharmacopeia (Ph. Eur.), and China Pharmacopeia (CP); 21 CFR Part 11 compliance and data security packages are available.

Easily add new capabilities: The spectrometer identifies Thermo Scientific™ Smart™ Accessories, Nicolet iN5 IR Microscope, TGA-IR module, and numerous commercially available third-party accessories.

Discover more unknowns: Award-winning Thermo Scientific™ OMNIC™ Software is a well-known interface that has currently been upgraded to include OMNIC Specta Software that has a library of more than 9,000 chemical spectra, so that users can quickly identify unknowns with advanced multi-component search routines.

Build confidence with unrivaled support: keep your projects running on time  with service and support that only Thermo Fisher Scientific’s Unity Lab Services and qualified dealer network can offer (over 7,000 service engineers and 1,800 technical support personnel globally).
