GENERAL OVERVIEW
Q: What is the VPXL used for?
The Computrac® Vapor Pro® XL, VPXL is a moisture-specific analyzer designed to measure water content in a wide range of materials. It is used in quality control, R&D, plastics, and production environments to ensure product consistency and performance across industries like pharmaceuticals, chemicals, polymers, and food.
Q: How is the VPXL different from Karl Fischer titration?
The VPXL is a chemical-free alternative to Karl Fischer (KF) moisture analysis. Unlike KF:
- No hazardous reagents or chemicals are required
- Minimal sample preparation is needed
- Faster results are achieved in minutes
- Lower operator risk and disposal concerns
It delivers comparable accuracy and repeatability while simplifying workflows and improving safety.
SETUP & INSTALLATION
Q: How easy is it to set up and start using the VPXL?
Begin by assembling the Model G Laboratory Stand and mounting the instrument. Connect the power supply, remove the shipping cap, and turn on the instrument. DVPlus will guide you through digital leveling using on-screen prompts to ensure proper setup before testing.
TESTING & MEASUREMENT
Q: How do I perform a viscosity test on the DVPlus?
The VPXL is designed for fast onboarding and easy operation:
• Simple installation on a stable, well-ventilated surface
• Guided setup for gas connection and system checks
• Ready for testing after a short warm-up period (~20 minutes)
Most users can be trained and fully operational in less than a day.
TESTING & MEASUREMENT
Q: How do you run a moisture test on the VPXL?
A typical test follows a simple workflow:
• Select or confirm a test program
• Prepare and load the sample into a vial & VPXL
• Press TEST to begin analysis
• View results and optional moisture curve graph
The process is designed for minimal operator input and consistent results.
