The release of the new model QCII+ XRF brings better detection limits with lower stray light, faster shaping times and flatter baselines for better peak discernment.
The QCII+ XRF is well suited to more demanding Quality Control applications such as verification of product conformance to regulatory requirements, eg ASTM D4294, ISO13032, AWPA A9 and Pharmaceutical Specifications. Other applications where the improved detections limits make the QCII+ XRF ideal are light element applications (Na – Cl) such as cement production.
The added dimension to this model is due to the new optics kernel with the new graphene window, reconfigured optics and large area detector.
The QCII+ can be connected to a network or LIMS system for better transfering of results.
Safety includes key operation for on/off functions and a stronger sample compartment door with dual locking mechanism.
SDD detector for superior resolution and sensitivity
Sealed optics and electronics to work in harsh environments
Inbuilt intel processor with touch icon interface
Multiple automated tube filters for enhanced sensitivity
Convenient built in thermal printer
Low cost with unmatched performance-to-price ratio
Applications
The NEX QC+ model uses a silicon drift detector which affords better sensitivities and counts compared to the Si PIN diode detector by 3-10 fold. An example of the improved sensitivity is for coal analysis where Chloride and Phosphorous can also be analysed as well as Sulphur. The coal application can also be extended to include predicted ash content, making for a fast method for coal type identification compared to combustion methods with long elapsed time.
The SDD detector also has better resolution for medium and heavy matrices such as ore samples.
Typical applications include:
Coal – S, Cl, P, Ash content
Oil – S, Cl
Smelting – Ca, Si, S, Cr, Ni
Coatings – Si
Milk – Fe, Ca
Ore analysis- Fe, Si, Cu, Zn, Ag, Pb
