Mira handheld Raman analysers

Mira handhelt Raman analyzer

Metrohm Instant Raman Analysers (Mira) are robust and reliable portable spectrometers for material identification and verification.

These instruments combine ease of use with maximum safety and provide results within seconds. Using ORS, Mira systems yield highly reliable results, giving you more confidence in your measurements.

We offer two versions of Mira Analysers:

  • Mira M-3: instrument for material verification compliant with FDA 21 CFR Part 11
  • Mira M-1: instrument for material identification

Barely larger than a smartphone the Mira M-3 is one of the fastest and most compact Raman spectrometers on the market.

With the Mira M-3, you will be able to ensure smooth and efficient processes, as you will get a reliable "Pass" or "Fail" result in 15 to 20 seconds on average.

The instrument and dedicated MiraCal 3.0 software is compliant with 21 CFR Part 11 regulations, making the Mira M-3 the ideal instrument for material verification in regulated industries.

  • Get fast, accurate, and reliable results

  • Ensure regulatory compliance (FDA 21 CFR Part 11)

  • Simplify raw material verification


The Mira M-1 is a robust, easy-to-use Raman spectrometer for material identification.

This light, compact, and handy instrument provides results in a matter of seconds. It allows you to identify a variety of materials, as it comprises a spectral library of more than 9000 Raman spectra.

You also have the option of populating customized libraries with your own measured spectra. This "open library" principle gives you maximum flexibility when designing your libraries.

Orbital Raster Scan: for improved reproducibility and accuracy

With ORS, the laser beam is not static, but moving in a circular motion. The instrument does not collect the spectrum from one point, but rather from an area. This makes the results more reliable, and provides a unique sampling advantage for heterogeneous material.

ORS achieves an outstanding resolution even for heterogeneous samples. Also, ORS prevents heat buildup in the sample and thus reduces the risk of degradation or ignition.

Maximum flexibility thanks to different modes and accessories

Mira handheld Raman spectrometers offer you maximum flexibility and safety. You can analyse samples either in vials that are inserted into the vial attachment or directly in the plastic or glass containers or packages. The range of accessories for Mira analysers include:
