Aplicación de cristales de seleniuro de zinc ATR en la preparación de muestras para espectrómetros de infrarrojos
Leer másAttenuated Total Reflection (ATR) is one of the most widely used non-destructive sampling techniques in Fourier Transform Infrared (FTIR) spectroscopy. When combined with zinc selenide (ZnSe) crystals, it enables fast and reliable analysis of liquids, pastes, powders, polymers, rubber, and soft materials without complex preparation procedures. This method has become a standard configuration in routine […]

Cómo preparar gránulos de KBr para un análisis FTIR preciso
Leer másKBr pellet preparation is one of the most widely used sample preparation methods for Fourier transform infrared spectroscopy (FTIR) when analyzing solid samples. A high-quality KBr pellet should be transparent, uniform, and free from contamination or moisture interference. If the pellet contains water, trapped air, oversized particles, or an uneven sample ratio, the final spectrum […]

How to Troubleshoot High Background Noise in FTIR Spectroscopy
Leer másHigh background noise is one of the most common issues encountered in FTIR spectroscopy. Excessive noise can reduce the signal-to-noise ratio, distort spectral peaks, and make qualitative or quantitative analysis unreliable. In severe cases, baseline drift and atmospheric interference can completely mask weak absorption bands. To effectively troubleshoot FTIR noise problems, it is best to […]
