NEX QC

NEX QC is optimized for quality control applications

Specifically designed for routine quality control applications, the new Rigaku NEX QC features an intuitive "icon-driven" touch screen interface for easy operation and a built-in printer for convenience. The shuttered 50 kV X-ray tube and Peltier cooled semiconductor detector deliver exceptional short-term repeatability and long-term reproducibility with excellent element peak resolution. This high voltage capability (50 kV), along with multiple automated X-ray tube filters, provides a wide range of applications versatility and low limits-of-detection (LOD). Options include fundamental parameters, automatic sample changer, sample spinner and helium purge for enhanced light element sensitivity.

Silicone Drift detector technology

A silicon drift detector (SDD) affords extremely high count rate capability with excellent spectral resolution. This enables NEX QC+ to deliver the highest precision analytical results in the shortest possible measurement times. The unique engineering feature of SDD is the transversal field generated by a series of ring electrodes that forces charge carriers to “drift” to a small collection electrode. Current generation SDD detectors, with the field effect transistor (FET) moved out of the radiation path, represent the state-of-the-art in conventional EDXRF detector technology.

Introduction

The versatile Rigaku NEX QC series of EDXRF spectrometers delivers routine elemental measurements across a diverse range of matrices — from homogeneous liquids of any viscosity to solids, thin films, alloys, slurries, powders and pastes.

Especially designed and engineered for heavy industrial use, whether on the plant floor or in remote field environments, the superior analytical power, flexibility and ease-of-use of the NEX QC series add to its broad appeal for an ever expanding range of applications, including exploration, research, RoHS inspection, and education, as well as industrial and production monitoring applications.

The NEX QC with its small footprint and light weight of 16kgs, it is well suited for portable mining laboratories.

Measures

With a silicon PIN diode detector, the NEX QC offers the best sensitities in the light matricies such as liquids and wood samples. Some examples include:

Liquid fertilisers – K & P

Biodiesel, Oil – S & Cl

Lubricant additives – Mo

Paint – Ti, Si

Solvents – Fe

With liquid samples the NEX QC can use the UltraCarry accessory. This allows liquid sample droplets to be concentrated to provide better detection levels by up to 3-5 times. This is ideal for volatile samples.

The NEX QC can be used for wood & timber analysis. Examples include:

CCA addition – Cu, Cr, As

Penta addition – Cl

ACZA addition – Cu, As, Zn

IPBC addition – I

Other examples of solid sample analysis include:

Ore analysis – Fe, Cu, Zr, Ru

Metal alloys – Al, Fe, Cu, Zn
