Procedure— Where the individual monograph specifies that the water content is to be determined by Method Ib, transfer 35 to 40 mL of methanol or other suitable solvent to the titration vessel, and titrate with the Reagent to the electrometric or visual endpoint.

规程---当各论规定使用方法Ib测定水的含量时，转移35~40ml的甲醇或者其他合适的溶剂至滴定容器中，用卡尔试剂滴定，以永停法或视觉观察终点。

Procedure— Unless otherwise specified, transfer 35 to 40 mL of methanol or other suitable solvent to the titration vessel, and titrate with the Reagent to the electrometric or visual endpoint to consume any moisture that may be present.

操作---除另有规定外，转移35~40ml的甲醇或其他合适的溶剂至滴定容器中，以永停法或视觉指示终点，用卡尔试剂滴定可能存在的水汽（所消耗体积忽略不计，因为不会代入到公式计算），快速加入测试样本，混匀，然后再次用卡尔试剂滴定到终点。

After desorption, the eluate was concentrated and then crystallized with methanol. The white powder obtained was analyzed by HPLC and the purity was 95%.

最后还对高稳定性的SAM硫酸对甲苯磺酸双盐的制备进行了研究，获得了纯度达98％的SAM硫酸对甲苯磺酸双盐。

The gradient elution of methanol in ammonium acetate buffer allowed elution of all the amines in less than 30 min.

For copper-treated chloroform extracts the total yield always increases, whereas that of the methanol extracts does not. GC-MS analysis on the fractions from EOM is carried out. No effect on the saturated hydrocarbons is found. For aromatic hydrocarbons copper has no influence on some samples and strong influence on the other.

沥青族组分分析表明，铜的加入对饱和烃在定性和定量两方面基本没有影响；部分样品的芳烃也基本无变化，但另外一些样品的芳烃差别却很大，这些样品加铜后得到的芳烃要比不加铜的在数量上高出几倍。

Lower temperature and higher pressure favored the promotion of carbon equilibrium conversion rate and methanol concentration.

低温和高压有利于提高碳的平衡转化率和甲醇的浓度。
