StableBond柱：采用了较大的二异丁基(SB-C18)或二异丙基(SB-C8、SB-C3、SB-Phenyl、SB-CN、SB-Aq)侧链基团和空间位阻，避免了在低pH条件下的水解破坏，其pH1.0~8.0，温度上限也可达到80~90℃，甚至在100%水相中也有出色的表现。2024/8/315色谱柱ZorbaxExtendC18柱：采用独特的双配位C18-C18键合技术，使的在高pH条件下使用硅胶基色谱柱成为可能，在pH2~11.5的范围内是稳定的。2024/8/316USP(32)<621>:Stationaryphasesformodern,reverse-phaseliquidchromatographytypicallyconsistofanorganicphasechemicallyboundtosilicaorothermaterials.1.Particles：usually3to10μmindiameter；mayrangeupto50μmormoreforpreparativecolumns.2.Internaldiameters：usually2to5mmforanalyticalseparation，lagerforpreparativechromatography.3.Temperature:onlyrarelyabove60℃；4.根据填料不同，USP在ChromatographicreagentsintheReagents,Indicators,andSolutionssection列出了USP-NF所用到的不同类型的柱子，如下所示:C-18硅胶柱C-8NH2柱阳离子交换柱（SCX）CN柱苯基柱阴离子交换柱（SAX）L57~L67未列出2024/8/319EP(6.0)2.2.29：

大部分分离机制都是基于以化学键合硅胶作为固定相，极性溶剂作为流动相的色谱条件。而化学键合相的性质往往决定了色谱系统的分离性能。2024/8/320particlesize：3~10μminternaldiameters：prescribedinthemonograph,eg:pH：silicabasedreversed-phasecolumnsareconsideredtobestableinmobilephaseshavinganapparentpHintherange2.0to8.0.temperature:notbeheatedabove60℃Special：EP(6.0)2.2.29：stationaryphasedegradetioncompositionofthemobilephase2024/8/321EPMannitolAssay:2024/8/322JP(XV)：Acolumnwithastationaryphasechemicallyboundontheinsidewallinsteadofthecolumnpackedwiththepackingmaterialmaybeused.2024/8/323检测器CHP(2010):UVDADFLDECDELSDRIDMS优点：灵敏度高、噪音低、线性范围宽、对流速和温度的波动不灵敏，适用于梯度洗脱及制备色谱。

缺点：只能检测有紫外吸收的物质，流动相的选择有一定限制，流动相的截止波长必须小于检测波长。适用范围：大多数有紫外吸收的化合物。优点：通用型检测器，对各种物质有几乎相同的响应。缺点：灵敏度相对较低，流动相必须是挥发性的，不能用非挥发性的缓冲盐及表面活性剂。适用范围：适用于挥发性低于流动相的组分，主要用于糖类、高级脂肪酸、磷脂、维生素、氨基酸、甘油三酯、皂苷及甾体等等无紫外吸收或紫外末端吸收的化合物的检测。优点：灵敏度高、选择性好，是微量组分和体内药物分析常用的检测器之一。缺点：只适用于能够产生荧光的物质的检测，适用范围不如紫外检测器。影响因素较多。适用范围：具有天然荧光的物质或通过荧光衍生化变成荧光衍生物后测定，主要用于氨基酸、多环芳烃、维生素、甾体化合物及酶等的检测。优点：灵敏度很高，尤其适用于痕量组分分析。缺点：干扰比较多，对温度和流速的变化比较敏感。适用范围：应用范围广，凡具氧化还原活性的或经衍生化后具氧化还原活性的物质。优点：灵敏度高，选择性好，能同时给出组分的结构信息。缺点：响应信号受离子化效率限制，仪器较为昂贵，流动相必须是挥发性的，不能用非挥发性的缓冲盐及表面活性剂。适用范围：组分的结构鉴别，微量及痕量组分的分析，药物代谢分析等。优点：通用型检测器，只要组分的折光率与流动相的折光率有足够的差别就能检测。缺点：灵敏度低、受环境温度、流量及流动相组成等波动的影响大，一般不能用于梯度洗脱。适用范围：RID为通用型检测器，适用于无紫外吸收化合物的分析，如糖类分析。2024/8/324USPandEPUSP(32)EP(6.0)Fixed,variableandmulti-wavelengthdetectorsarewidelyavailable.UV、RID、FLD、ECD......Newdetectorscontinuetobedevelopedinattemptstoovercomethedeficienciesofthosebeingused.UV/Visspectrophotometers,includingdiodearraydetectors,arethemostcommonlyemployeddetectors.2024/8/325流动相CHP(2010)反相系统首选甲醇-水系统（采用紫外末端波长检测，首选乙腈-水系统）缓冲盐：少用，尽可能低反相色谱系统，C-18柱，有机相比例应不低于5%。USP(32)High-purityreagentsand“HPLCgrade”organicsolventswater:lowcondutivityandlowUVabsorptionEP(6.0)Fornomal-phasechromatography,lesspolarsolventsareemployed.Wateristobestrictlycontrolled!0.45μmdegassedbysparingwithhelium,sonicationorusingon-linemembrane/vacuumAdjustmentofthepH,iseffectedusingonlytheaqueouscomponentofthemobilephaseandnotthemixture.2024/8/326系统适用性SystemSuitability2024/8/327定义CHP(2010):色谱系统的适用性试验通常包括理论板数、分离度、重复性和拖尾因子四个参数，其中，分离度和重复性尤为重要。ICHdefinition:Systemsuitabilitytestingisanintegralpartofmanyanalyticalprocedures.Thetestsarebasedontheconceptthattheequipment,electronics,analyticaloperationsandsamplestobeanalyzedconstituteanintegralsystemthatcanbeevaluatedassuch.2024/8/328DefinitionEP(6.0):Thesystemsuitabilitytestsrepresentanintegralpartofthemethodandareusedtoensureadequateperformanceofthechromatographicsystem.Thevariouscomponentsoftheequipmentemployedmustbequalifiedandbecapableofachievingtheprecisionrequiredtoconductthetestorassay.USP(32):
