Основные моменты

Quantitative Analysis from Calibration to Reporting

The new DQUANT is the ideal tool for both, experienced lab managers and operators running the daily jobs. The software comes with predefined work-flows to set up the following analytical methods:

Calibration with reference materials
Drift correction
Modules and logical sequences
Addition method
Absorption method for filter sample holders (NIOSH 7500)
Ratio method

Whereas the calibration is always defined interactively, unknown samples may either be evaluated in a simplified graphical user interface, or fully automated in the console mode after the measurement has finished.

Особенности

User Guided Calibration

DQUANT combines an intuitive graphical user interface with work-flow guidance. Pre-configured walk-down data trees are implemented for the different analytical tasks.

The calibration curves and the intensity-drift correction are established and verified in the user interface. The experienced user may also analyze unknown samples interactively.

Concentration-modules allow for tailor-made reporting of results derived from the calibrated concentrations.

最大的分析是通过使用灵活性g intensity-modules. The built-in formula editor allows for easy column arithmetic of intensities. This gives access to any kind of user defined intensity corrections, peak overlap correction or simply averaging intensities in order to reduce preferred orientation effects.

Operator Friendly Evaluation

DQUANT allows for a fully automated data evaluation without user interaction. For those users who do not wish to run their quantitative analysis in full black-box mode, a simplified user interface is provided. It allows the operator to load a verified calibration and to analyze batches of unknown samples.

For the evaluation of unknown samples there is no need to modify a calibration. Instead, results are generated for a whole series of samples in one run and presented in the layout, which is defined in the calibration project file.

Several table layouts for the results presentation are provided.
They contain different levels of information. The results preview allows further customization, export to spreadsheet calculation programs, printing or export to document formats such as PDF or XPS.

Furthermore, results may be transferred to the instrument database for further evaluation using the DIFFRAC.SUITE RESULTS MANAGER.

Automated Measure.Evaluate.Report

DQUANT employs the full power of the DIFFRAC.MEASUREMENT package to simplify quantitative analysis. Measurement jobs link the scan and evaluation conditions to the sample IDs of the unknown samples, standards or drift monitor samples.

The data evaluation in DQUANT and the results presentation may either be triggered automatically or performed by the operator manually. This whole procedure becomes particularly easy since it is literally as simple as pushing a button.

What is your analytical challenge?

Silica Dust Monitoring

Micro-crystalline silica is a typical component of soil and rocks but is also contained in foundry materials or concrete. Occupational exposure to respirable silica is a preventable health hazard. Exposure limits were issued by several national authorities and therefore, concentrations of silica are to be monitored. The DIFFRAC.DQUANT software is used to establish norm compliant drift corrected calibrations, evaluate unknowns to a quantification limit as low as 5 microgram, and to report the results directly to the laboratory LIMS system or to the internal instrument database. It fully supports absorption correction as requested by NIOSH 7500 or segment calibrations.

Retained Austenite

XRD and DIFFRAC.DQUANT are used to quantify Austenite, a phase which correlates with the strength and other mechanical properties of steel. The Ratio Method is used for calculating concentrations directly from the intensities. Protocols such as ASTM E 975 or SAE SP-453 provide standardized procedures for obtaining results with an accuracy level of 0.5% or better. Looking at multiple peaks provides further information about the presence of texture in the steel.

Aluminum Production

The so called “Potflux” method determines the composition of the smelter cells during the metal production by combining XRF data of the Ca concentration with concentrations of typical minerals simultaneously in DIFFRAC.DQUANT. From the mineralogy of the congealed electrolyte control parameters are derived that are essential for managing the operation of the smelter cells, the consumption of raw materials and electricity which is a major cost factor in Aluminum production. Furthermore, the anode quality is monitored by XRD and DIFFRAC.DQUANT.
