Stop Ion Suppression! The #1 LC-MS/MS Mistake You're Making
Low sensitivity? Weird calibration curves? Your internal standard CVs are terrible? You probably have ion suppression - and it's likely caused by poor sample preparation.
🔬 What You'll Learn:

The biggest mistake causing matrix effects in LC-MS/MS
Why protein precipitation alone isn't enough
Post-column infusion testing to find suppression zones
How to optimize your gradient to avoid matrix interference
Source parameters that minimize ion suppression
When to use SPE vs LLE vs simple dilution

💡 Practical Tips Covered:
✓ Sample cleanup optimization for biological matrices
✓ Phospholipid removal techniques
✓ Chromatographic separation strategies
✓ ESI source optimization for dirty samples
✓ When to switch ionization modes
