The PeakSeeker by Raman Systems is our most practical and easy-to-use Raman spectrometer. It is an excellent choice for users who want a full featured Raman spectrometer but have a limited budget. The PeakSeeker is ideal for Raman feasibility studies, teaching labs, or fundamental research.

The PeakSeeker is extremely versatile for measuring multiple sample types. Sampling accessories include a vial holder for liquids and powders.  A fiberoptic probe supports remote sample access. User friendly software and USB connectivity enables truly plug and play Raman spectroscopy.

Our handheld spectrometers have been featured on the CBS show Crime Scene Investigation and on National Geographic TV:




Versatility: The user can sample solids, liquids, and powders even when inside transparent packaging and containers such as bags, bottles and vials.

Sensitivity: The highly sensitive CCD detector features a wide spectral range and uses frames based integration to minimize the need for sensor cooling. Deep blocking laser rejection filters obstruct Rayleigh scatter and isolate Raman scatter for valuable molecular analysis.

Portability: The spectrometer is small and lightweight. Rugged construction and ergonomic design allow it to be carried just about anywhere and set up for immediate use.

Simplicity:  Each PeakSeeker system includes a notebook PC pre-loaded with RSIQ software for true point-and-click operation. Sample spectra are acquired within seconds.

Adaptability: Optional software add-ons:

  • RSIQ-QUAL enables substance ID by a database search of thousands of reference spectra using commercially available spectral libraries. Users can also create unique libraries.
  • RSIQ-QUANT is a multivariate analysis tool and
  • RSIQ-CFR supports 21 CFR Part 11 compliance for cGMP electronic records and signatures.
