Introduction, molecules are created in structure-controlled biochemical operations. The molecular uniformity and consistency of these materials is prerequisite to ordered structures and life. Aside from these key substances, molecular heterogeneity can be found even in natural polymers, e.g. in cellulose and natural rubber.作者: 萬(wàn)神殿 時(shí)間: 2025-3-22 20:11 作者: annexation 時(shí)間: 2025-3-23 00:38

Quantitative Evaluation and Calibration,d not only make quantitative evaluation illusive but also may severely falsify even qualitative conclusions. Since these effects disturb the common linear dependence of peak area on sample size, quantification of suitable calibrating chromatograms is strongly recommended.作者: 考古學(xué) 時(shí)間: 2025-3-28 17:06
