The Fourier transform infrared spectrometer (FTIR) is a standard tool for analyzing the composition of polymer materials and identifying quality. The three major mainstream brands on the market—Thermo Fisher (Nicolet series), Bruker (TENSOR/INVENIO series), and Shimadzu (IRTracer series)—each have their own technical features and applicable scenarios.

Thermo Fisher Nicolet is the brand with the highest market share in the global FTIR market. Core advantages of high-end models like the Nicolet iS50: diamond ATR accessories (excellent durability and luminous flux), built-in standard spectral libraries (containing hundreds of thousands of polymers, additives, etc.), and highly automated OMNIC software (one-click identification). For QC labs that need to perform rapid and frequent ingredient identification, Nicolet's efficiency advantage is evident.

Bruker's differentiation lies in optical design and research scalability. Its RockSolid™ interferometer permanently calibrated design reduces maintenance costs, and the INVENIO series is highly scalable—it can be upgraded from basic FTIR to microinfrared, FTIR imaging, and even Raman integration. On open and shared platforms for universities and research institutions, Bruker appears very frequently.

Shimadzu's strengths lie in cost-effectiveness and software compatibility with other Shimadzu analysis systems (GC, LC, MS). The IRTracer-100 stands out in its resolution (0.25cm⁻¹) and signal-to-noise ratio (60,000:1) at the same price point. For laboratories already operating in the Shimadzu ecosystem, choosing Shimadzu FTIR enables seamless integration at the data management level.
