Raman Spectrometers

A Raman Spectrometer

For Quality Data Collection & Fast Analysis

Introducing the compact, high-performance ReactRaman Raman Spectrometer, coupled with iC Raman 7 and trusted service and support, provides critical insight – even for the most challenging reactions. ReactRaman is ideal for:

• Multiphasic Reactions
• Crystallization
• Polymorph Detection

One Click Analytics (only available in iC Raman 7) means that whether you are an expert, or new to Raman Spectrometers, data collection and analysis is fast and accurate.    

Small Footprint, Big Performance

ReactRaman Raman Spectrometer combines best-in-class performance with a flexible and portable design; delivering outstanding results wherever it’s needed - on the bench, in the fume hood, or in the lab next door.

One Click Analytics

Designed specifically for time-resolved reaction analysis, iC Raman software combines a peak picking algorithm with functional group intelligence to drastically reduce analysis time. Users combine knowledge of their chemistry with an automated data analysis workflow to ensure correct interpretation for every experiment.

In Situ Probes Optimized for Quality Answers

Raman spectrometer probe- and flow-based sampling technologies are optimized for crystallization and polymorph chemistry investigation. Fit-for-purpose materials of construction make data collection straightforward in acidic and corrosive environments across a wide range of temperatures and pressures.

Additional Understanding for Your Reaction Analysis

Raman spectrometers provide complimentary, but different, information to FTIR. While FTIR gives users functional group information, Raman provides backbone and structural information. When combined with FTIR, the user can obtain key information regardless of the sample physical state, giving its user a full picture of their reaction. 

Reaction Analysis Expertise

As a company, METTLER TOLEDO has over 30 years of dedicated reaction analysis experience. This is our focus and our passion. For our Raman spectrometer, this is revealed in the details. Our probes and instrumentation have been optimized for detection. Our software was configured to guide the users through collection and analysis steps for results confidence.  Our trusted service and support teams ensure success for the scientist. 

Comprehensive Reaction Understanding

with ReactRaman Raman Spectrometer

In order to understand chemical reactions, chemists must address the following:

• When does the reaction start? When does the reaction stop?
• What polymorph is being produced?
• What are the reaction kinetics, mechanism, or crystallization process?
• Did it react as expected? Did any by products form, and why?
• What happens if reaction temperature, dosing rates, or mixing rates change?

Traditionally, to obtain reaction information, samples are taken for offline analysis using HPLC.  For chemistries in which sample removal results in the loss of key information, or are toxic or otherwise hazardous, this procedure is not straightforward.  Furthermore, chemists must be present to take the sample and then wait for the results before reaction analysis can begin.

With inline Raman Spectrometers, continuous monitoring allows users to trend components over time for a 'molecular video' of the reaction - making it easy to answer critical questions for reaction and process optimization.
