SPE stuck? Your sample won’t flow through the cartridge? You’re not alone. Genevie Hodson, Senior Manager of Technical Support and Applications at Phenomenex, shares a step-by-step way to fix it.

• First, time the issue ⏱️: during conditioning/blank, during loading, or after loading?
• Viscous or cloudy samples 🥣: Dilute, centrifuge, filter—or use larger particles (Strata XL 100 µm vs Strata-X 33 µm).
• Low manifold pressure 🧰: Check the manifold, instrumentation, and individual positions.
• Immiscible solvents 🚫💧: Use only mutually miscible pairs (avoid hexane with water).
• Precipitation/proteins 🧪: Dilute, reduce volume, avoid denaturing solvents, pre-wash with a low ionic strength buffer.

• Pro tip 💡: Change one variable at a time to isolate the root cause.

Restore flow, reduce downtime, and keep your SPE running smoothly.

Why Won't My Sample Flow Through an SPE Cartridge? Troubleshoot SPE flow problems by identifying common causes such as viscous samples, manifold pressure issues, solvent incompatibility, and precipitation.
