In the world of Fourier Transform Infrared or FTIR Spectroscopy, three components form the backbone of reliable and precise molecular analysis: the interferometer, the laser, and the infrared (IR) source. These elements ensure that every PerkinElmer FTIR instrument (e.g., Spectrum Two) operates with the highest level of accuracy, stability, and longevity.
PerkinElmer, a global leader in analytical instrumentation, now reinforces this reliability by offering an unmatched 10-year warranty on these three critical components—Interferometer, Laser, and IR Source—in its FT-IR spectrometers.
🔬 The Interferometer – Heart of the FTIR
At the core of the FTIR system lies the interferometer, typically a Michelson design. It splits the IR beam into two paths, reflects them back via fixed and moving mirrors, and recombines them to create an interferogram. This is the raw data used to generate high-resolution IR spectra after Fourier transformation.
PerkinElmer’s patented DynaScan™ interferometer eliminates the need for dynamic alignment, ensuring:
- Long-term mechanical stability
- Enhanced durability
- Reduced need for maintenance
This innovation is one reason why PerkinElmer confidently backs its interferometer with a 10-year warranty.
💡 The Laser – Guiding Precision
The laser in an FTIR instrument acts as a calibration reference. It doesn’t interact with the sample but is used to track the moving mirror’s position with high accuracy.
Typically, a He-Ne laser (632.8 nm) is used for:
- Monitoring mirror displacement
- Ensuring accurate wavenumber calibration
- Improving signal reproducibility
A malfunctioning laser can compromise data quality. That’s why a long-life laser, guaranteed for 10 years, adds peace of mind and confidence in consistent performance.
🔥 The IR Source – Energy that Drives Molecular Excitation
The IR source generates the infrared radiation needed to probe molecular vibrations. Most FTIR systems use a Globar (silicon carbide rod), which emits a wide IR spectrum when heated to ~1200°C.
Key benefits of PerkinElmer’s IR sources include:
- Broad and stable emission spectrum
- Long operational life
- Consistent output intensity
The 10-year warranty ensures users won’t face unexpected downtimes or replacement costs for a full decade.
🛡 Why the 10-Year Warranty Matters
FTIR users in industries such as pharmaceuticals, chemicals, polymers, food testing, and research labs rely on accurate, uninterrupted performance. With PerkinElmer’s 10-year warranty on all three major components, users get:
- Confidence in uptime
- Lower cost of ownership
- Trust in engineering durability
- Maximum return on investment
🏆 Choose Reliability. Choose PerkinElmer.
