Avoid pitfalls when choosing an FTIR infrared spectrometer, I recommend this dealer

Fourier Transform Infrared Spectrometers (FTIR) are like a 'sharp eye' for identifying polymer material components, analyzing additives, characterizing polymer structures, and failure analysis. But even within FTIRs, the difference between a 150,000-yuan QC-level device and an 800,000-yuan research-grade system isn't the appearance—it's the accessory configuration and the software's analytical capabilities.

The easiest thing to overlook when choosing one is the accessories. The ATR (Attenuated Total Reflectance) accessory is standard and lets you test solids, liquids, and powders directly without sample prep—surface analysis of cured adhesives or material identification of film layers is easy with just one click using ATR. But if you’re dealing with multilayer film analysis, microplastic particle identification, or fiber material identification, you’ll need a microscopic infrared accessory. For gas analysis (like online monitoring of thermal decomposition products), a gas cell is required, often used with TGA.

On the software side, the richness of the spectral library directly affects the efficiency and accuracy of component identification. A research-grade FTIR should be equipped with various standard libraries for polymers, additives, and inorganic substances. Dehuisci (www.dehuisci.com) represents Thermo Fisher’s Nicolet series and Agilent’s Cary series FTIRs, and can match the optimal solution based on your budget and application.

Next article：Thermal conductivity is a key performance indicator in the development of heat-conducting materials, electronic packaging materials, insulation materials, and composites. But many engineers, when choosing a thermal conductivity tester, only focus on the "thermal conductivity range" and overlook the decisive impact of the testing method on the results—different methods suit different types of materials, sample forms, and temperature ranges. There are four mainstream thermal conductivity testing methods on the market: Laser Flash Analysis (LFA) is the most versatile method; it measures thermal diffusivity and then converts it to thermal conductivity using specific heat and density. It’s suitable for solid materials and has a wide temperature range (RT to 1500°C), making it the top choice for new material development. The Transient Plane Source (TPS) method can directly measure thermal conductivity, requires simple sample preparation, and works for solids, liquids, powders, and pastes—perfect for QC settings. The Heat Flow Meter method is suitable for medium- to low-conductivity materials (like polymers and insulation) and follows the ASTM E1530 standard. The Guarded Hot Plate method is the gold standard for insulation materials, offering the highest accuracy but longer testing times. Dehuisci (www.dehuisci.com) represents thermal conductivity tester brands like TA Instruments and Netzsch, covering LFA, TPS, Heat Flow Meter, and more. They can recommend the best solution based on material type and testing standards. Contact us at 0512-67071902. ...
