Choosing the right spectrometer for Raman and FTIR Spectroscopy

Anton Paar offers two exceptional spectroscopy instruments: the Lyza 7000 FTIR Spectrometer and the Cora 5001 Raman Spectrometer. This guide highlights the distinct advantages of each to help you choose the best fit for your needs.

Fourier Transform Infrared (FTIR) Spectroscopy

FTIR spectroscopy is the favoured method for identifying organic and some inorganic materials by measuring their absorption of infrared light at different wavelengths. It's ideal for comprehensive material verification and quality control.

Anton Paar’s Lyza 7000 leverages cutting-edge FTIR technology, providing precision and versatility for analysing solids, liquids, and gases.

Key features include:

• Guided workflows: Intuitive touchscreen and embedded software.
• Rapid and reliable measurements: Ideal for quality control.
• Robust design: Durable with a hermetically-sealed aluminum optics compartment and cube corner interferometer.

Raman spectroscopy

Raman spectroscopy is suited for minimal sample interaction where clear substance characterisation is required without altering the sample state.

Anton Paar’s Cora 5001 is a state-of-the-art benchtop Raman spectrometer known for its precision and ease of use. Raman spectroscopy identifies chemical compounds without the need for any sample preparation.

Key features include:

• Autofocus: The unique autofocus guarantees precision and ease of use.
• Minimal sample preparation: Allows direct analysis through glass or plastic containers, ideal for rapid substance identification.
• Sampling accessories: Regardless of whether the sample is a solid, liquid, or powder, Cora 5001 has the appropriate sample holder for it.

Choosing the right spectrometer

FTIR is highly recommended for comprehensive analytical tasks that require detailed information and quality control for a wide array of sample types, including deeply-coloured and fluorescent samples. For many samples, established SOPs (e.g. ASTM standards) for IR spectroscopy are available.

Raman is best suited for rapid, non-invasive testing and precise substance identification, particularly in pharmaceutical and forensic settings. Samples can be measured through packaging, allowing the measurement of air- and moisture-sensitive materials. Cora 5001 includes a battery option for analysis directly in the field.

Enhanced efficiency and compliance with Spectroscopy Suite

Anton Paar’s Spectroscopy Suite integrates with both Lyza 7000 and Cora 5001, providing solutions tailored for regulated environments.

Key benefits include:

• Efficiency: Predefined workflows speed up measurements and prevent errors.
• Compliance: Adheres to 21 CFR Part 11 and EU GMP Annex 11.
• Data integrity and management: Ensures lifetime data integrity with versioned methods, secure electronic signing, active directory, and comprehensive data management.
