Question: What is a good method of analyzing powders for composition?
Keywords: ft-ir,powder,composition,measuring,measure,particles,particle
Answer: A method known as Fourier transform-infrared (FT-IR) spectroscropy is often used for this purpose. FT-IR sends light beams of varying wavelength through the sample and the reflected light is analyzed by spectroscopy to find the absorption of each wavelength. The measured wavelengths are compared with a reference laser and the sample composition can be calculated. Analect Instruments Inc. specialize in FT-IR measurement. Visit their website below.
