Difference between Spectrum One and Spectrum 100 FTIR
“Spectrum One” and “Spectrum 100” refer to two models of FTIR (Fourier Transform Infrared) spectrometers manufactured by PerkinElmer, a company that produces analytical instruments. The names “Spectrum One” and “Spectrum 100” are specific to the product line, and different models may exist within each category. The primary differences between them may lie in their specifications, features, and performance characteristics. As of my last knowledge update in January 2022, I don’t have detailed specifications for individual models released after that date.
