+## L389-101 操作规程
+
+检验依据：QAS-ZJ389-101-03
+
+### 1. 有关物质
+
+#### 1.1. 色谱条件
+
+色谱柱型号：Waters Xbridge Shield RP18
+色谱柱规格：150mm x 4.6mm x 3.5um
+流速：1.0 mL/min
+波长：225 nm
+运行时间：24 min
+后运行时间：6 min
+柱温：40 °C
+进样量：5 uL
+流动相A：称取 1.36g 磷酸二氢钾于 1L 纯化水中，用磷酸调 pH=3.0&#177;0.02
+流动相B：乙腈
+
+**注意：流动相A需用于配制配样溶剂，请确保配制的量足够。**
+
+梯度程序：
+
+| 时间(min) |  A%   |  B%   |
+| :-------: | :---: | :---: |
+|     0     |  70   |  30   |
+|     3     |  50   |  50   |
+|     7     |  15   |  85   |
+|   17.5    |  15   |  85   |
+|   17.6    |  70   |  30   |
+|    24     |  70   |  30   |
+
+#### 1.2. 样品配置
+
+**溶剂**：乙腈:流动相A = 1:1
+
+**灵敏度溶液**：移取 25uL 的样品溶液于 25mL 容量瓶中，定容。
+
+**专属性储备液**：分别称取 12～15mg 乙基三苯基溴化膦、三苯基磷、三苯基氧膦对照品于 50mL 容量瓶中，定容。
+
+**专属性溶液**：称取 23～27mg 的 L389-101 对照品于 100mL 容量瓶中，加入专属性储备液 1mL，定容。
+
+**样品溶液**：称取 23～27mg 样品于 100mL 容量瓶中，定容。
+
+#### 1.3. 容量瓶用量
+
+| 规格(mL) | 数量  |
+| :------: | :---: |
+|    25    |   1   |
+|    50    |   1   |
+|   100    |   2   |
+
+每多一批样品则多加 1 个 100 mL 容量瓶
+
+#### 1.4. 进样顺序
+
+**注意：样品溶液超过五针或测试时间超过五小时，需要回一针灵敏度溶液和专属性溶液。**
+
+样品溶液不超过五针：
++ 空白
++ 灵敏度溶液
++ 专属性溶液-1
++ 专属性溶液-2
++ 样品溶液
+
+样品溶液超过五针或测试时间超过五小时：
++ 空白
++ 灵敏度溶液-1
++ 专属性溶液-1
++ 专属性溶液-2
++ 样品溶液
++ 灵敏度溶液-2
++ 专属性溶液-3
+
+#### 1.5. 系统适用性要求
+
++ 样品溶液图谱中主峰保留时间与对照品应一致
++ 专属性溶液中分离度不低于 1.5
++ 灵敏度溶液主峰的信噪比 &ge; 10
++ 专属性溶液平行测定的两次及回标的专属性溶液中，三苯基氧膦的峰面积百分比差值应不高于 10%
+
+三苯基氧膦峰面积百分比差值 = ( 峰面积最高值 - 峰面积最低值 ) / 峰面积平均值 * 100%
+
+#### 1.6. 标准要求
+
++ 总杂 &le; 5.0%
