色谱柱名词解释

色谱柱是色谱分析中使用的一种关键设备，用于将混合物中的成分分离并进行定性和定量分析。

以下是一些与色谱柱相关的常见名词解释：
1. 固定相（Stationary Phase）：色谱柱中的固定涂层或填料，具有特定的化学性质和分离能力。

样品在固定相中发生相互作用，导致不同成分以不同速度移动并被分离。

2. 流动相（Mobile Phase）：用于携带样品通过色谱柱的流体，可以是气体（气相色谱）或液体（液相色谱）。

流动相的选择取决于分析目标和色谱柱类型。

3. 柱效（Plate Number）：用于描述色谱柱分离能力的度量。

柱效越高，表示色谱柱的分离效果越好。

4. 保留时间（Retention Time）：在色谱柱中，样品组分从进样到检测器出现的时间。

保留时间可以帮助确定化合物的特征和纯度。

5. 色谱峰（Chromatographic Peak）：色谱图中呈现出的高度峰值，表示在特定保留时间内检测到的样品成分。

6. 柱温（Column Temperature）：色谱柱的操作温度，可以对分离效果和分析速度产生影响。

某些分析方法需要在特定的温度下进行。

7. 柱寿命（Column Lifetime）：色谱柱使用期限，取决于使用条件和期间的保养和维护。

柱寿命的结束通常由分离性能下降或峰形变得不规则来决定。

L1和L8是美国药典(USP)规定的色谱柱编号，其实就是C18柱和NH2柱。

系统适应性——美国药典系统适应性是气相和液相色谱分析方法的重要组成部分，用于证明色谱系统的分离度和重现性能满足样品的分析要求。

测试基于这样的原理：仪器、电路、方法和样品组成一个整体系统，我们可以对这个系统进行测试评估。

影响色谱系统的因素包括：流动相的组成、离子强度、温度和pH值柱子大小、流速、柱温和压力固定相特点，包括填料类型，载体形状、粒径、孔径、表面积等。

常用固定相为反相硅胶，以十八碳烷基健合硅胶最常用，其它经过化学修饰的硅胶也有使用。

分离度Rs是理论塔板数n的函数（也叫柱效），α是分离因子，k是容量因子（所有符号的意义见前文“色谱定义和说明”部分）。

在规定的色谱条件下，n表示洗脱物中相邻化合物的分离程度，可作为衡量色谱系统柱效能的指标，但是不如直接测试的结果可靠。

峰的尖锐程度部分反映柱效，这个参数对检查微量物质至关重要。

标准品或者标准溶液需要重复进样以确保精密度。

除非个论中有规定, 系统适用性五针的数据的相对标准偏差不超过2.0%, 如果超过2.0%的话, 需要进样六针。

在含量测定中，如果纯品含量100%，则相对标准偏差没有最大值限制，这个值可根据多次进样对照溶液来计算：%RSD=KB/t90%，n-1K为常数0.349，由公式k=(0.6/)×(t90%,5/)计算得来，表示B=1.0时六次进样的相对标准偏差。

B是个案中规定的上限。

n是对照溶液的进样次数（3≤n≤6），t90%,n-1是自由度为n-1、置信水平为90%，双侧检验时的t值。

除非另有规定，RSD不能超过下表中的值。

此规定不适用于相关物质检测。
