HPLC有关物质分析方法验证

HPLC有关物质分析方法验证

HPLC有关物质分析方法验证HPLC(高效液相色谱)是一种常用的物质分析方法,广泛应用于药品、食品、环境等领域。

为了保证分析结果的准确性和可靠性,对HPLC方法进行验证是非常必要的。

HPLC方法验证包括了准确性、精密度、线性范围、灵敏度、特异性和系统适应性等方面的评估。

首先,准确性是衡量方法是否精确地测量目标物质含量的能力。

方法准确性的验证包括添加回收试验、标准品浓度重现性试验以及样品稀释后的测试。

通过添加已知浓度的目标物质到待测样品中,在不同浓度下测定回收率,可以评估方法的准确性。

其次,精密度是衡量方法在短期内进行重复实验的一致性。

精密度的验证包括了重复测定试验以及系统精密度试验。

通过重复测定同一样品多次,计算相对标准偏差,可以评估方法的精密度。

线性范围是指方法在一定浓度范围内的目标物质含量与测定结果之间的关系。

验证线性范围时,需要测试少量目标物质的浓度,以及相对较高的浓度,测定结果在一定限度内应与浓度成比例关系。

灵敏度是指方法在检测限下测定目标物质的能力。

灵敏度的验证包括了检测限试验和定量限试验。

检测限试验是通过在基质中添加多个不同浓度的目标物质溶液,确定出检测限。

定量限试验是通过在基质中添加不同浓度的目标物质溶液,确定出定量限。

特异性是指方法所测定的目标物质与其他干扰物之间的选择性。

特异性的验证包括了干扰物试验和选择性试验。

通过加入干扰物到目标物质溶液中,然后进行测定,确定干扰物是否对结果产生影响。

选择性试验是通过测定其他可能存在的相关物质浓度,确定是否与目标物质有影响。

最后,系统适应性主要是验证HPLC仪器和设备的稳定性和可靠性。

系统适应性的验证包括了仪器精度试验和仪器稳定性试验。

精度试验是通过测定标准品溶液的浓度,评估仪器的精度。

稳定性试验是在一定时间范围内,对同一样品进行多次测定,评估仪器的稳定性。

在进行HPLC方法验证时,需要根据相关规范文件,制定详细的验证计划和方案,确保验证方法的全面性和科学性。

HPLC分析方法验证指导原则

HPLC分析方法验证指导原则

HPLC分析方法验证指导原则产品质量标准分析方法验证的目的是证明采用的方法适合于相应检测要求。

在建立产品质量标准时,分析方法需经验证;在产品生产工艺变更、配方的组分变更、原分析方法进行修订时,则质量标准分析方法也需进行验证。

方法验证理由、过程和结果均应记载在产品标准起草说明或修订说明中。

需验证的分析项目有:鉴别试验,杂质定量检查或限度检查,有效成分含量测定,以及其他成分(如防腐剂等)的测定。

验证内容有:准确度、精密度(包括重复性、中间精密度和重现性)、专属性、检测限、定量限、线性、范围和耐用性。

视具体方法拟订验证的内容。

附表中列出的分析项目和相应的验证内容可供参考。

方法验证内容如下:一、准确度准确度系指用该方法测定的结果与真实值或参考值接近的程度,一般用回收率(%)表示。

准确度应在规定的范围内测试。

1.含量测定方法的准确度原料药可用已知纯度的对照品或样品进行测定,或用本法所得结果与已知准确度的另一个方法测定的结果进行比较。

制剂可用含已知量被测物的各组分混合物进行测定。

如不能得到制剂的全部组分,可向制剂中加入已知量的被测物进行测定,或用本法所得结果与已知准确度的另一个方法测定结果进行比较。

如该分析方法已经测试并求出了精密度、线性和专属性,在准确度也可推算出来的情况下,这一项可不必再做。

2.杂质定量测定的准确度可向原料药或制剂中加入已知量杂质进行测定。

如不能得到杂质或降解产物,可用本法测定结果与另一成熟的方法进行比较,如药典标准方法或经过验证的方法。

在不能测得杂质或降解产物的响应因子或对原料药的相对响应因子情况下,可用原料药的响应因子。

应明确表明单个杂质和杂质总量相当于主成分的重量比(%)或面积比(%)。

3.数据要求在规定范围内,至少用9个测定结果进行评价,例如,设计3个不同浓度,每个浓度各分别制备3份供试品溶液,进行测定。

应报告已知加入量的回收率(%),或测定结果平均值与真实值之差及其相对标准偏差或可信限。

No differences in specificity, selectivity or column performance should be observed. RobustnessRobustness determinations are essential when transferring analytical methods from the development laboratory to the commercial plant quality control laboratory. There may usually be a difference in columns or HPLC machine models used. Deliberate variations according to the following table were made to the critical parameters of the method such as column, flow rate and concentration of [organic acid] in the mobile phase.

REPRODUCIBILITY (INTRA-LAB)T his intra-laboratory precision or the precision between laboratories is known as reproducibility or more specifically - intra-laboratory reproducibility. Both the above are ruggedness - and a USP requirement.[8]RUGGEDNESS&Robustness- (Tabulations - continued).The Results (Average assay % for Analyst 1 and 2 ) are tabulated.RUGGEDNESSANALYSTNo 1%ASSAYColumn IANALYSTNo 2%ASSAYColumn 212345678910Mean (% Accuracy) =Standard Deviation =% Coef of Variation =R obustness.The evaluation of robustness should be finalized at the end of the development phase - around the time of the process qualification lot manufacture. The robustness evaluation should be developed with the commercial laboratory equipment in mind. It should show the reliability of an analysis with respect to deliberate variations in the method parameters A consequence of robustness evaluation is that a series of system suitability parameters are established to ensure that the validity of the analytical procedure is maintained whenever used.Robustness is defined by both the USP and the ICH Tripartite guidelines as "a measure of its capacity to remain unaffected by small but deliberate variations in method parameters and provides an indication of its reliability during normal use " Robustness is defined both in the USP and ICH, but is not required.[9]Stability of Standard solutionsRe-chromatography of ten replicate single injections of the same standard solution (which have been allowed to stand for x hours ) against freshly prepared Standards showed no significant differences from the original results.STABILITY OF STANDARD SOLUTIONSmg/100mL Initial Analysis(Date)mg/100mL Repeat Analysis 2nd (Date)1 injection2 injection3 injection4 injection5 injection6 injection7 injection8 injection9 injection10 injection1 injection2 injection3 injection4 injection5 injection6 injection7 injection8 injection9 injection10 injectionMeanStandard Deviation Relative Standard Dev.=== NMT 2.0 %[10]Typical Chromatograms.Representative chromatograms of the following traces are routinely provided:-♦ System Suitability♦ Standard Solution♦ Drug Product♦ placeboTypical ChromatogramsWhen R epresentative Chromatograms are displayed - all peaks are LABELED with the peak name and RRT.R epresentative chromatogramDrug Product[11]Conclusion .(Closing Statement)A n appropriate conclusion should be given stating clearly that:“The method # IAG00-005 Ed.
