In order to verify the effectiveness of the process, comparative chemical analyses (cellulose, hemicelluloses, lignin, extractives, ash, buffering capacity, and pH) of the untreated and acetylated heartwood and sapwood were carried out for both species for the first time. Diffuse reflectan...
the FTIR operator can quickly use the chemical “fingerprint” of the sample to correlate it to a compound in the database. In addition to efficiently verifying incoming raw materials, FTIR may be instrumental in flagging a contaminant in the material, identifying a formulation mistake, or trouble...
FTIR (Fourier Transform Infrared) and ATR (Attenuated Total Reflection) are common techniques used in the field of spectroscopy for chemical analysis. Both techniques require regular calibration to ensure the accuracy and reliability of the results obtained.红外光谱(FTIR)和衰减全反射(ATR)是化学分析领域...
