NiFeCo-FP

Accurate elemental analysis of NiFeCo alloys

Special steels, high-temperature alloys and superalloys are used in a wide variety of high-performance components for their characteristics such as durability, hardness, temperature stability and corrosion resistance. The production of high-specification steels requires process and quality control with very strict tolerances. The challenges of analyzing a large variety of alloying elements with wide ranges of concentrations by XRF are well known to the metals industry. In particular, the matrix corrections needed and the large number of reference materials required for high-quality results are generally a concern. 

Nifeco1.jpg

The Metals edition of Zetium with NiFeCo-FP is the solution to these challenges. Malvern Panalytical’s Fundamental Parameter (FP) matrix correction algorithm is used to provide a single application program for wide-range alloys analysis of up to 21 elements.

Cu-base-FP 

Accurate elemental analysis of Cu metals

‘Copper-base’ (Cu-base) is a term used to describe a range of alloys where Cu is the principal component. In order to make the materials suitable for different applications (e.g. the manufacture of coinage, bells, a wide range of mechanical equipment and electrical wiring), Cu is normally alloyed with elements such as Sn, Zn, Ni, Al, and Pb. During the production process fast chemical analysis is needed to minimize errors in production and to maximize production yield. The Cu-base-FP package (including applicable calibration standards) covers the analysis of this wide range of Cu alloys by using Malvern Panalytical’s Fundamental Parameter (FP) model.

Low alloy steel analysis with Malvern Panalytical XRF spectrometers

Excel your analysis with Malvern Panalytical’s pre-calibrated solutions

Low_AlloySteel1.jpg

Low alloy steels are widely used for the production of pipes, automotive and aerospace bodies, railway lines and offshore and onshore structural engineering plates. High-strength low alloy steel is used in these areas due to its corrosion resistance properties. Low alloy steels tipically contain less than 10% alloying elements (C, Mn, Cr, Ni, Mo, V and Si combined). Accurate and fast elemental analysis is a critical requirement during the production of steel. It is not only required for compliance with quality standards, but it also enables the steel producer to save costs in an increasingly competitive environment.

To address the needs of the steel making industry with regard to speed and flexibility in analysis, Malvern Panalytical X-ray sequential and simultaneous spectrometers Zetium and Axios FAST can be delivered pre-calibrated with a low alloy steel (LAS) package. The pre-calibrated solution is based on more than 90 certified reference materials (CRMs) covering for a wide elemental range of up to 21 elements and four monitor samples for drift- and sample preparation correction.

LAS pre-calibration for Zetium and Axios FAST spectrometers 

The low alloy steel (LAS) calibration has been setup using more than 90 certified reference materials sourced from several suppliers. To pre-calibrate Zetium and Axios FAST spectrometers, this master calibration is transferred using six CRMs using the SuperQ Calibration update.

Low_AlloySteel2.jpg

Hi-Per channels – for higher sensitivities and quicker analysis 

Zetium and Axios FAST can be fitted with either one or two Hi-Per channels for increased sensitivity for elements from boron to magnesium. Hi-Per channels use curved, multi-layer crystals to focus incoming radiation. This results in a short optical path length, delivering intensities significantly higher than conventional channels.

RoHS Calibration Standards for XRF 

The perfect combination: Epsilon 3X with RoHS Calibration Standards for screening and quantification 

Polymeric compliance is important and requires that no restricted substances are present in materials. Aiming for restricted substance levels in polymers that just comply, can go wrong when materials are combined because the cumulative quantities can be higher than accepted limits.

Epsilon 3X is ideal for low-level screening, whereas Epsilon 3XLE, with best-in-class performance, is ideal for low-level quantification at low mg/kg (ppm)-levels. With virtually no sample preparation, it is now possible to determine accurately these elements at sub mg/kg levels when calibrating with the RoHS Calibration Standards.

GPC and SEC Standards

A range of molecular weight standards for different applications of GPC/SEC

Malvern Panalytical offers a wide range of molecular weight standards for GPC/SEC for conventional and universal calibration as well as light scattering.


Malvern offers a wide selection of molecular weight standards for GPC/SEC. These are available as pre-weighed standards for ease of preparation. Simply add the correct volume of the required solvent to prepare these molecular weight and intrinsic viscosity standards at a known and accurate concentration.


Standards for conventional and universal column calibration have a broad molecular weight range and are available for organic and aqueous applications.


Standards for light scattering and triple detection are characterized using instruments verified with NIST-traceable materials and are available for organic and aqueous applications.  They can be used to simultaneously calibrate and normalize detectors and to determine inter-detector volumes and peak broadening parameters.

  • Pre-weighed molecular weight standards reduce preparation time and effort and increase reproducibility
  • Column calibration standards cover a wide molecular weight range
  • NIST-traceable light scattering/triple detection standards
  • Calibrate and normalize detectors and calculate detector offsets and band broadening corrections in a single step to reduce calibration time
  • Polystyrene and PMMA standards for organic applications
  • Polyethylene oxide, pullulan and dextran standards for aqueous applications

Malvern Panalytical’s molecular weight standards are pre-weighed into a glass vial. Simply add the desired amount of solvent to achieve the right concentration.

Column calibration standards are run in series through a GPC/SEC system. The elution times of the various molecular weight standards are then used as a reference for the unknown material. Relative molecular weights are obtained when the standard and sample polymers are different.

Light scattering/triple detection standards are used to characterize the detector responses which are then used in the measurement of absolute molecular weight. Normalization factors, detector offsets and band broadening corrections are calculated simultaneously to reduce calibration time.
