✅ 🔬 How It Works?

The TJ270-30A operates using a dual-beam infrared optical system, which splits the IR source into two paths—one for the sample and the other for the reference. This configuration minimizes drift and compensates for background interference, improving signal stability. Controlled via a user-friendly Windows-based software, the system enables precise spectral acquisition, real-time baseline correction, and advanced data operations like smoothing, differentiation, and arithmetic analysis. The result is high-resolution IR spectra ideal for structure elucidation and compound identification.
