色谱柱名词解释

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。

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。
