EDXRF for Everyday Quality Control
Fast, non-destructive elemental testing made simple
The NEX QC II Series simplifies routine quality control and elemental testing. These compact benchtop EDXRF analyzers deliver fast results for solids, liquids, powders, and thin films—ideal for everyday quality control in labs, plants, and production environments. Designed for ease of use, the NEX QC II and NEX QC II+ feature intuitive operation with an embedded computer and built-in printer, so your team can get results quickly with no specialized technical background required. The first-generation NEX QC+ QuantEZ remains available for users who require expanded method development, advanced calibration strategies, and optional compliance features, including 21 CFR Part 11 support.
NEX QC II Series Overview
Trusted technology, next-generation performance
The NEX QC II Series is a second-generation line of energy dispersive X-ray fluorescence (EDXRF) analyzers built on the proven NEX QC platform. Designed specifically for industrial quality control, the systems deliver fast, non-destructive elemental analysis with no technical background required.
Its compact, rugged design is built for tough environments, and the embedded computer and built-in printer eliminate the need for PCs on the plant floor. The clear, icon-driven touchscreen interface guides you through setup to results, minimizing training time and reducing operator error.
This new design incorporates graphene window silicon drift detectors, refined optics, upgraded electronics, improved detector protection, and a redesigned touchscreen interface. These enhancements support fast, reliable measurements with minimal training and make the system easy to use across production floors, manufacturing lines, and laboratory settings. Compared to the original NEX QC models, NEX QC II instruments offer improved measurement performance, better light-element sensitivity, and a more intuitive interface.
The series includes two models, the NEX QC II and NEX QC II+, to accommodate different performance needs and budgets. The first-generation NEX QC+ QuantEZ is available for users who need the advanced capabilities of the QuantEZ platform.
Simple, fast quality control testing
Model: NEX QC II
The NEX QC II provides multi-element testing across a wide range of materials, making it an excellent fit for daily QC tasks, incoming and outgoing material checks, and at-line verification.
Designed for simple operation, the NEX QC II features an embedded computer and a clear, icon-driven touchscreen interface that guides users through setup and measurement. Most operators can begin running samples with only a brief introduction. Its small footprint fits easily into tight spaces, and the built-in printer offers fast, on-demand reporting at the instrument.
Product highlights:
- Compact, space-saving design, no external computer required
- Intuitive touchscreen interface for ease of training and operation
- Reliable general-purpose performance for routine QC applications
- Built-in printer for immediate reporting
- Optional carrying case for portability
Enhanced performance, same simplicity
Model: NEX QC II+
The NEX QC II+ is the higher-performance model in the new generation, offering enhanced sensitivity for light elements and improved spectral resolution. Its upgraded SDD allows QC teams to meet tighter specifications and handle more demanding applications with confidence. It is ideal for facilities that need increased throughput or light-element performance without adding operational complexity.
Product highlights:
- Higher-resolution graphene window SDD for improved sensitivity
- Ideal for more demanding QC environments requiring tighter specs
- Enhanced light-element performance
- Same simple, intuitive touchscreen operation as NEX QC II
Expanded capabilities and compliance options
Model: NEX QC+ QuantEZ
The NEX QC+ QuantEZ remains available as a software-driven model for users who require the advanced capabilities of the QuantEZ platform. Unlike the embedded touchscreen systems in the NEX QC II Series, the first-generation QuantEZ model operates from an external PC, supporting more flexible method development and calibration strategies.
This model is well-suited for laboratories or regulated environments that need additional features such as RPF-SQX Fundamental Parameters software, or optional compliance tools like SureDI for 21 CFR Part 11 support.
Product highlights:
- PC-based QuantEZ software for advanced capabilities
- Supports RPF-SQX Fundamental Parameters software
- SureDI option available for FDA 21 CFR Part 11 compliance
