🔧 HPLC故障排除——决策树 6 常见问题

6种最常见HPLC问题的诊断及决策树（每个问题5个步骤）。 来源： Snyder/Kirkland/Dolan 3rd ed. Chapter 17 + LCGC LC Troubleshooting columns 1989-2024.

宽峰 medium

症状： 色谱图上所有峰都比预期宽（半峰宽 > 2倍正常值）

🔍 诊断树：
  1. 1. 检查是所有峰变宽还是只有部分峰
    → 是： 所有峰→仪器问题（色谱柱或系统）
    → 否： 仅部分峰→化学问题（特定分析物与色谱柱的相互作用）
  2. 2. 更换测试柱——问题是否消失？
    → 是： 色谱柱已耗尽——填料损坏，前几毫米有空隙。更换。
    → 否： 液相色谱系统问题
  3. 3. 检查死体积——进样环、连接件、检测器
    → 是： 对于4.6 mm色谱柱，进样环 > 100 µL或连接松动→更换卡套，缩短管路
    → 否： 继续诊断
  4. 4. 温度测试：将色谱柱从25°C升至40°C
    → 是： 峰变窄→传质动力学过慢（升高温度）
    → 否： Continue
  5. 5. 检查流速与该色谱柱的最佳范德姆特值
    → 是： 4.6mm/5µm的最佳流速为1.0 mL/min，2.1mm/3µm的最佳流速为0.4 mL/min
    → 否： Continue
⚠️ 常见原因：
  • 色谱柱已耗尽（无保护柱时超过2000次进样）
  • 系统死体积 > 100 µL（错误的进样环、长管路、卡套松动）
  • 温度过低（传质动力学）
  • 流速超出范德姆特最佳值
  • 样品溶剂比流动相A更强
✓ 修复方法：
  • ✓ 更换色谱柱（当>2000次进样时）
  • ✓ 检查所有连接——管路尽可能短
  • ✓ 将色谱柱温度升至40°C（如果物质稳定）
  • ✓ 将流速降至van Deemter最佳值
  • ✓ 将样品溶解在流动相A中（而非纯有机相）
峰拖尾（拖尾因子T > 1.5） high

症状： 峰在晚洗脱侧有延伸的“拖尾”（根据USP，不对称度T = b/a > 1.5）

🔍 诊断树：
  1. 1. 物质是否含有碱性基团（氨基、吡啶）？
    → 是： 是 → 硅醇相互作用！向流动相A中添加0.1% TFA或5-10 mM TEA。
    → 否： Continue
  2. 2. 检查流动相pH与物质pKa的关系
    → 是： pH = pKa ± 1 → 部分电离，峰分裂。使pH远离pKa ≥ 2个单位。
    → 否： Continue
  3. 3. 检查色谱柱使用时间（>1500次进样？）
    → 是： 是 → 硅醇暴露（柱流失）。更换为具有更高封端度的色谱柱（XTerra、Symmetry）。
    → 否： Continue
  4. 4. 样品是否含有金属（来自玻璃小瓶的Fe、Cu）？
    → 是： 是 → 使用II型无色小瓶或PFA小瓶。向样品中添加0.1mM EDTA。
    → 否： Continue
⚠️ 常见原因：
  • 硅醇相互作用（碱性分析物 + 硅胶游离硅醇）
  • pH处于分析物pKa边界（峰分裂）
  • 旧色谱柱（柱流失，高硅醇活性）
  • 样品中的金属（螯合 → 拖尾）
  • 色谱柱过载（4.6mm色谱柱上>50 µg）
✓ 修复方法：
  • ✓ 向流动相A中加入0.1% TFA（UV）或0.1%甲酸（LC-MS）
  • ✓ 选择高纯度封端的色谱柱：Waters XBridge BEH、Phenomenex Kinetex
  • ✓ 在pH值距离pKa ≥ 2个单位的条件下操作
  • ✓ 向样品中加入0.1mM EDTA（螯合Fe/Cu）
  • ✓ 对于4.6 mm色谱柱，将进样体积减少至≤ 20 µL
基线漂移 medium

症状： 基线在>5分钟内系统性上升或下降

🔍 诊断树：
  1. 1. 是否使用梯度（B%增加）？
    → 是： 是 → 流动相A与B在检测波长下吸收不同。溶剂更换导致UV截止波长变化。检查有机相UV吸光度百分比。
    → 否： 继续（等度）
  2. 2. 检查色谱柱温度——是否稳定在±0.5°C？
    → 是： 是（稳定）→ 继续
    → 否： 不稳定 → 开启柱温箱（>25°C受控）
  3. 3. 测试：关闭自动进样器，仅运行泵+色谱柱+检测器
    → 是： 漂移消失 → 自动进样器污染（清洁针头、隔垫）
    → 否： Continue
  4. 4. 检查灯的使用时间（UV用D2灯）
    → 是： 是（>1500小时）→ 更换灯
    → 否： Continue
⚠️ 常见原因：
  • 梯度洗脱，流动相UV截止值不同
  • 色谱柱温度不稳定
  • 自动进样器针头/隔垫污染
  • UV灯老化（>1500h）
  • 检测器流通池污染
  • 色谱柱未平衡（<10个柱体积）
✓ 修复方法：
  • ✓ 用100% A预平衡色谱柱10-15个柱体积
  • ✓ 开启色谱柱恒温箱，温度30-40°C稳定
  • ✓ 用50:50乙腈-水溶液清洗检测器流通池
  • ✓ 如果D2灯使用时间>1500小时，请更换
  • ✓ 使用基线扣除（Chromeleon、Empower原生功能）
无峰/丢失峰 critical

症状： 预期分析物峰未出现在色谱图上

🔍 诊断树：
  1. 1. 进样是否实际发生？
    → 是： 检查自动进样器日志、泵压力（进样时应下降）
    → 否： 自动进样器问题→检查定量环、进样针、样品瓶中的样品
  2. 2. 样品是否在样品瓶中（体积正确，未蒸发）？
    → 是： Continue
    → 否： 无样品——重新移液
  3. 3. 样品稳定性——制备时间是否超过24小时？
    → 是： 是→降解。重新制备新鲜样品。
    → 否： Continue
  4. 4. 检查检测波长与物质的λmax是否匹配
    → 是： 检测波长与λmax不匹配→无信号。扫描DAD 200-400nm。
    → 否： Continue
  5. 5. 测试：进样纯标准品（已知浓度，新鲜）
    → 是： 标准品出峰→样品问题（基质、衍生化）
    → 否： 标准品也无峰→系统问题（色谱柱、流动相、梯度）
⚠️ 常见原因：
  • 样品未从样品瓶中抽取（自动进样器故障）
  • 样品降解（超过24小时，pH/温度/光照）
  • 检测波长错误
  • 流动相错误（例如忘记加TFA）
  • 色谱柱接反/固定相错误
  • 物质在死时间（V0）洗脱→无保留，不可见
✓ 修复方法：
  • ✓ 严格按照协议重新制备新鲜样品
  • ✓ 紫外-可见DAD扫描200-400nm并搜索λmax
  • ✓ 检查流动相组成——是否添加了TFA？
  • ✓ 测试色谱柱反向（小心！）
  • ✓ 对于保留时间<1分钟——降低B比例，用甲醇代替乙腈
  • ✓ 在插件方法库中检查预期保留时间
压力过高 critical

症状： 泵压力>色谱柱最大压力的80%或系统因高压错误停机

🔍 诊断树：
  1. 1. 检查色谱柱是否连接正确（箭头方向）
    → 是： OK
    → 否： 色谱柱接反→将其翻转（切勿反向安装运行）
  2. 2. 测试：从系统中移除色谱柱，仅运行泵+检测器
    → 是： 压力降至 <50 bar → 色谱柱问题（堵塞）
    → 否： 压力保持高位 → 在线过滤器堵塞，烧结滤片污染
  3. 3. 检查预柱过滤器（在线烧结滤片）
    → 是： 污染且变棕色 → 更换
    → 否： Continue
  4. 4. 用 50:50 ACN:H2O 反向冲洗（不带色谱柱）——问题消失？
    → 是： 颗粒卡在第一毫米处——冲洗 30 分钟可能恢复
    → 否： 更换色谱柱
⚠️ 常见原因：
  • 在线过滤器（烧结滤片）被颗粒堵塞
  • 缓冲盐析（高 %B 时沉淀）
  • 样品含有悬浮物（进样前用 0.22 µm 过滤）
  • 色谱柱堵塞（柱床压实）
  • 梯度含缓冲液相 + 高有机相 → 盐沉淀
✓ 修复方法：
  • ✓ 进样前务必用0.22 µm PVDF过滤样品
  • ✓ 每100次进样（或压力升高>20%时）更换在线过滤器
  • ✓ 不要使用>20mM磷酸盐缓冲液+>70%乙腈（盐会析出）
  • ✓ 用50:50乙腈:水反向冲洗色谱柱30分钟（如果制造商允许）
  • ✓ 使用4×3mm预柱保护主色谱柱
鬼峰 high

症状： 色谱图上校准中不存在的无法解释的峰

🔍 诊断树：
  1. 1. 测试：空白进样（纯样品溶剂）
    → 是： 出现鬼峰 → 系统或洗脱液污染
    → 否： 仅与样品一起出现 → 基质
  2. 2. 鬼峰是否随梯度增大（在高 %B 下洗脱）？
    → 是： 是 → 色谱柱过载或前一次运行中的强保留物质
    → 否： 与梯度无关 → 自动进样器残留
  3. 3. Increase carryover wash (between injections)
    → 是： 有帮助 → 残留是原因。使用更强的清洗程序。
    → 否： Continue
  4. 4. 纯水进样——是否有峰？
    → 是： 是 → 水源污染（来自 DI 系统的有机物）
    → 否： Continue
⚠️ 常见原因：
  • 自动进样器针/定量环中的残留
  • 洗脱液污染（即使是 HPLC 级）
  • 前一次运行中的强保留组分
  • 样品瓶中的塑料（邻苯二甲酸酯、来自瓶盖的 PEG）
  • 纯化不充分的去离子水
✓ 修复方法：
  • ✓ 加强清洗程序：100% B → 100% A → 50:50（3个循环）
  • ✓ 校准前进行强清洗：100% DMSO或100%甲醇
  • ✓ 如有疑问，用0.22 µm PTFE过滤洗脱液
  • ✓ 使用琥珀色玻璃瓶和聚四氟乙烯内衬盖盛装样品
  • ✓ 定期进行梯度升至100% B并持续10分钟（清洗）

  • Heparyna
    Umiarkowane
    CAS partnera: 9005-49-6 · DrugBank DB01109

    Mechanizm: DMSO zwiększa przepuszczalność błon biologicznych i może nasilać układową absorpcję heparyny stosowanej miejscowo. Dodatkowo DMSO wykazuje słabe działanie antyagregacyjne (hamowanie OH• i fibryny).

    Skutek kliniczny: Możliwe nasilenie efektu antykoagulacyjnego i ryzyka krwawienia, zwłaszcza przy aplikacji przezskórnej DMSO + heparyna.

    Postępowanie: Unikać łączenia w aplikacjach skórnych. Monitorować APTT/anty-Xa przy heparynie systemowej i ekspozycji zawodowej na DMSO.
