PortaSpec Series X vs. PortaSpec XRST: Choosing the Right WDXRF Analyzer for Your Operation

Cianflone Scientific’s PortaSpec line delivers reliable, laboratory-grade WDXRF performance in rugged, production-ready systems. Two of the most widely used models—PortaSpec Series X and PortaSpec XRST—offer distinct advantages depending on your sample volume, workflow, and operational needs. This comparison will help determine which model is best suited for your application.

PortaSpec Series X: Flexible, Multi-Element WDXRF for Diverse Sample Types

The PortaSpec Series X is designed to provide maximum flexibility without sacrificing analytical precision. It performs multi-element sequential analysis across the typical WDXRF range (Titanium through Uranium) and is built for operations that need versatility in sample size.

Key Advantages

• Accommodates Larger Samples — No Cutting, No Sizing: Accepts large or irregular sample sizes without trimming, saving time and labor.
• Multi-Element Capability: Supports up to five preset sequential elements.
• Broad Sample Flexibility: Ideal for solids, coatings, films, and powders.
• Integrated Computer System: Preconfigured for fast setup.
• Reliable, General-Purpose Operation: Great for labs needing flexibility without automation.

Best Fit For:

• QC labs with mixed sample geometries
• No-prep or minimal-prep sample workflows
• Multi-element analysis requirements
• Small to mid-volume testing

PortaSpec XRST: High-Throughput WDXRF with Automated Sample Handling

The XRST is engineered for productivity and efficiency. It maintains the accuracy of Cianflone’s WDXRF technology while adding automation to reduce labor and improve consistency.

Key Advantages

• Eight-Position Rotating Sample Tray: Load up to six samples for automated sequential testing.
• Integrated Computer System: Preconfigured and ready to operate.
• Configurable Element Analysis: Single, dual, or multi-element.
• Production-Level Efficiency: Optimized for automation and repeatability.

Best Fit For:

• High-volume QC environments
• Automated production lines
• Low-handling or batch testing operations
• Repetitive workflows
