Structured, Mechanistic Diagnosis for HPLC / LC–MS Systems
Sudden pressure spike?
Gradual pressure increase over weeks?
Pressure unstable during gradient?
Column change didn’t fix it?
High backpressure is one of the most common — and most misdiagnosed — chromatography problems.
This decision engine analyzes your system conditions and ranks the most probable mechanical and chemical causes, with confirmation tests and corrective actions.
🚀 What This Tool Does
The High Backpressure Troubleshooter evaluates:
- Column blockage
- Guard column contamination
- In-line filter clogging
- Mobile phase precipitation
- Buffer crystallization
- Pump check valve restriction
- Tubing / fitting blockage
- Gradient mixing artifacts
- Sample particulate contamination
Instead of trial-and-error, you receive:
- 🔎 Ranked root causes
- 🧪 Targeted confirmation tests
- 🛠 Step-by-step corrective actions
- 📘 Preventive maintenance guidance
Built for real laboratory workflows.
🎯 Designed For
- HPLC and LC–MS users
- Analytical chemistry labs
- Bioanalysis groups
- QC environments
- Method development teams
- Scientists maintaining regulated systems
Whether the issue is sudden or progressive, this tool narrows the cause quickly.
🧠 Why It’s Different
Most troubleshooting guides:
- Are static flowcharts
- Assume generic setups
- Ignore real-world system variables
- Provide long lists without prioritization
LabVeda combines:
- 15+ years of chromatography experience
- Structured diagnostic logic
- AI-assisted hypothesis scoring
- Practical confirmation workflows
You get ranked causes — not guesswork.
⏱ Takes 2–3 Minutes
Answer a short set of focused questions about:
- Pressure behavior
- System configuration
- Mobile phase conditions
- Recent changes
- Sample type
The engine calculates weighted probabilities and returns a ranked troubleshooting plan.
🧪 Example Output
Most Likely Cause: In-line filter restriction
Confidence: 72%
Why: Pressure increase gradual, unaffected by column swap, organic flush ineffective
Confirm: Remove/replace in-line filter
Fix: Replace filter and flush system
Prevent: Implement routine filter replacement schedule
Clear. Actionable. Lab-ready.
