In today’s fast-paced analytical laboratories, uptime is not just important; it is mission-critical. Whether you are running high-throughput bioanalysis, environmental testing, or pharmaceutical workflows, every minute of LC-MS downtime can impact productivity, data quality, and timelines.

That is why we are excited to introduce a smarter and faster way to troubleshoot.

Troubleshoot LC-MS like a pro

We are proud to launch the interactive LC-MS troubleshooting guide for SCIEX Triple Quad™ and QTRAP systems, which is now available on the SCIEX Now learning hub.

Built with direct input from our global customer community, this free, on-demand resource is designed to help you quickly diagnose and resolve common instrument challenges, without waiting for service intervention.

At SCIEX, our philosophy is simple: Customers talk, we listen. This guide is a direct reflection of that commitment.

Why this guide matters

Troubleshooting LC-MS systems can often feel complex and time-consuming. Traditional approaches may involve:

Waiting for service support
Running multiple diagnostic tests without clear direction
Experiencing extended instrument downtime

This interactive guide changes that. By enabling self-guided troubleshooting, you can:

Reduce downtime and keep your lab running efficiently
Minimize service costs by resolving common issues independently
wIncrease confidence in identifying root causes
Accelerate decision-making with structured guidance
Ultimately, it puts control back in your hands—right when you need it most.

Designed for real-world lab challenges

The guide focuses specifically on the most common issues encountered with Triple Quad and QTRAP LC-MS systems, based on real customer experiences and service data.

Rather than static documentation, it delivers a dynamic, decision-tree experience:

Start with your observed issue
Answer guided questions about system behavior
Follow a logical pathway toward diagnosis and resolution

This structured approach ensures you are not just guessing but systematically narrowing down the root cause.

Key features at a glance

Interactive, decision-based navigation
Quickly find relevant solutions through guided Q&A tailored to your specific problem
Step-by-step troubleshooting logic
Begin with the most likely and easy-to-fix causes before progressing to more complex diagnostics
Root cause testing guidance
Learn how to validate potential issues with clear, actionable instructions
Integrated learning recommendations
Access additional eLearning modules to deepen your expertise and prevent future issues
Content available in English and Japanese

Practical troubleshooting tips for LC-MS users

While the guide provides in-depth support, here are a few best practices every LC-MS user can apply:

Start simple: Always check LC solvent level and composition, connections, and system leaks before deeper diagnostics
Monitor system trends: Changes in sensitivity or retention time can signal early issues
Verify method parameters: Small changes in source conditions or gradients can have large impacts
Keep systems clean: Regular maintenance of ion sources and interfaces prevents many common problems
Document observations: Clear notes help accelerate troubleshooting, whether independently or with support

These habits, combined with the interactive guide, can significantly reduce disruption to your workflows.

Bonus tip: Watch our LC-MS/MS webinar series, “Maintenance and troubleshooting,” presented by Karl Oetjen, Senior Scientist for Technical Marketing and one of our resident PFAS experts at SCIEX, who helps you understand how to keep your system in tip-top shape and shows you a lot of tips and tricks to do so.

Supporting your success, every step of the way

This launch is part of our broader commitment to empowering laboratories with the tools, knowledge, and resources needed to succeed – independently and efficiently.

We are excited to hear your feedback as you begin using the guide, and we will continue evolving our resources based on your needs.

When your instruments perform at their best, so can you.

Why SCIEX partners with experts around the world

Innovation in mass spectrometry does not happen in isolation. Some of the most impactful scientific advances emerge from highly specialized research communities – proteomics experts developing new peptide identification workflows, metabolomics researchers curating spectral databases, toxicologists building compound libraries, and biopharma scientists creating novel characterization methods.

Managing ADC characterization: The challenge of turning complexity into confidence

Unlike traditional monoclonal antibodies, ADCs combine an antibody backbone with linker chemistry and a cytotoxic payload. This multi-component architecture introduces overlapping layers of heterogeneity, including drug-to-antibody ratio (DAR) distributions, charge variants, post-translational modifications, and structural changes at both the intact and subunit levels. Across ADC development, these characteristics are considered critical quality attributes that must be characterized, understood, and monitored.

3 reasons ZT Scan DIA is changing the game in metabolomics

For years, metabolomics researchers have faced a frustrating reality: modern high-resolution mass spectrometers can detect tens of thousands of molecular features, yet only a fraction can be confidently identified. The challenge is no longer finding molecules. It is generating the high-quality MS/MS data needed to confidently assign structures and extract meaningful biological insights.
