当该物品含有水合状态的水，按照具体各论中的规定，使用方法I（滴定法）、方法II（恒沸法）、或方法III（重量分析法），在标题水分项下给出。Many Pharmacopeial articles either are hydrates or contain water in adsorbed form. As a result, the determination of the water content is important in ...
can be estimated using the formula: FCV/KF in which F is the water equivalency factor of the Reagent, in mg per mL; C is the used volume, in percent, of the capacity of the buret; V is the buret volume, in mL; and KF is the limit or reasonable expected water content in the sam...
Elesclomol, a thiohydrazide derivative drug substance, was demonstrated to be a non-hygroscopic compound by GVS results. Water content for three batches at two stability conditions, as determined using direct cKFT, was displayed in Figure 2. The...

For MWHPO-MB, C element content increased obviously due to the adsorption of organic carbon compound, MB. Optimization of adsorbent components. Different component adsorbents usually show different adsorption performances. For the sake of comparison, MWHPO (number 1), MWHPO-GO-0.5 (number 2)...
In addition to the role that this phytohormone plays in normal development, ABA content is also in- creased in response to water deficit, preserving cell water content due to stomatal closure. In Arabidopsis, NCED5 acts in association with NCED3 to synthesize ABA under normal conditions and in...
In addition, the presence of non-protein nitrogen compounds such as nitrates, ammonia, urea, nucleic acids, free amino acids, chlorophylls, and alkaloids can lead to overestimations of the protein content. The analysis of the amino acid profile by HPLC-IC permits to estimate...
These strategies were evaluated under four population growth scenarios (very fast, fast, moderate and slow growths) by using several Key Performance Indicators (KPI's) including water demand, leakage levels, total costs, energy consumption, rainwater delivered and greywater recycled. Moreover, it ...
