Background and Introduction
Compass 200 X-ray fluorescent (XRF) analyzer has the capability to non-destructively quantify or qualify nearly any element in soil or mineral samples, depending on specific instrument configurations. It has already shown to successfully estimate a whole suite of soil parameters in a number of disciplines, including archaeology, geology, agronomy,and soil pollution . The analysis of soil elemental concentrations aids the assessment of soil
mineralogy, fertility, salinity, acidity,and cation exchange capacity (CEC), alongside metal uptake by plants and soil heavy metal contamination. Compared to conventional laboratory analysis, the determination of soil elemental concentrations by XRF is much faster, less expensive,and non-destructive. The best results are obtained when samples are homogenized, dried, finely ground, and sieved ,but sample preparation is not always necessary as Compass 200 can be directly employed in the field.
The Compass 200 makes it possible to perform efficient quantitative element analysis of soils with a minimum of sample preparation
Features:
>Strong software with standard-less fundamental parameters (FP) algorithm, or use its empirical calibrations when results traceability and superior accuracy are needed
>Extremely easy to use with Load-and-Start for sample analysis
>Minimal Sample Preparation: great for in-situ testing
>Fast Qualitative and Quantitative Analysis
>Advanced data management system with flexible multiple data transport methods including USB cable connection, storage card, Wi-Fi and Bluetooth
>No PC required, alleviating the worry of a computer crash and loss of data
Typical Applications:
>In-Situ Soil Screening/ soil surveys
>Waste effluent monitoring
>Contaminated land assessment/Hazardous and toxic metals in soil complied with EPA Method 6200
>Site remediation and validation/Ex-Situ Soil Analysis
>Pt, Pd and Rh in the catalyst
>Consumer goods testing: more precise testing for Pb, Cd in toys, jewelry, packaging, and food etc.
