aThe polysaccharides were grounded with KBr powder and then pressed into pellets for FTIR measurement in the frequency range of 4000–400 cm−1 多聚糖在4000-400 cm−1的频率范围着陆了与溴化钾粉末然后被按了入药丸为FTIR测量[translate]
Other important differences arise from the water content in the sample, as well as in the KBr powder utilized as reference and dilution. Some of these differences are discussed since they occur in regions usually utilized to check modifications in the wood. The effect of sample concentration is ...
