各论中未注明温度的,均指在室温下(10~30℃)进行。 |
EP |
Unless otherwise prescribed in the monograph, all measurements are carried out at the same temperature as that used for calibration (±2.5 °C), usually between 20 °C and 25 °C. |
USP |
Lab-based pH measurements are typically performed at 25 ± 2℃unless otherwise specified in the individual monograph or herein. |
JP |
In the pH determination, the temperature of a sample solution must be controlled to be the same as that of the pH standard solutions with which the pH meter was standardized (within 2℃). |

ChP |
除另有规定外,本法系采用钠光谱的D 线(589. 3nm)测定旋光度,测定管长度为1dm,测 定 温 度 为20°C 。 |
EP |
Determine the zero of the polarimeter and the angle of rotation of the liquid at a wavelength of 589 nm and a temperature of 20 ±0.5 °C, unless otherwise prescribed. |
USP |
Unless otherwise directed, measurements of optical rotation are made in a 1.0-dm tube at 589 nm at 25℃. |
JP |
The measurement is generally performed at 20℃or 25 ℃, using a 100-mm tube and the D line of sodium lamp as the light source. |

做法 |
ChP |
于25±2 °C —定容量的溶剂中,每隔5 分钟强力振摇30秒;观察30分钟内的溶解情况。 |
EP |
Shake vigorously for 1 min and place in a constant temperature device, maintained at a temperature of 25.0 ±0.5 °C for 15 min. If the substance is not completely dissolved, repeat the shaking for 1 min and place the tube in the constant temperature device for 15 min. |
USP |
NA |
JP |
Unless otherwise specified, solubility means the degree of dissolution of the JP Drugs, previously powdered in the case of a solid drug, within 30 minutes in a solvent at 20 ±5℃, by vigorous shaking for 30 seconds each time at 5-minute intervals. |
