Revolutionary COMPASS 200: Portable XRF Mobile Lab Transforms Element Detection For Healthy Soil & Crops

Soil, an essential strategic resource, plays a fundamental role in human survival. Among various soil pollutants, heavy metals stand out as a primary concern. Due to their inability to be decomposed by microorganisms, heavy metals tend to accumulate in the human body through the food chain, thereby posing significant risks to human health. Portable X - ray fluorescence (XRF) technology has been widely applied in monitoring heavy metals in soil for a long time. With the assistance of suitable reference materials, this technology can also accurately determine the concentrations of toxic metals in water, fertilizers, and crops. Moreover, by detecting the uptake of metals in soil and biomass, XRF technology effectively evaluates the efficiency of bio - remediation processes. In 2005, the United States Environmental Protection Agency (US EPA) issued a method regarding the use of field - portable XRF spectrometers for soil and sediment analysis. Subsequently, the International Organization for Standardization (ISO) established a relevant standard. XRF technology offers several advantages, such as being time - saving, cost - effective, and non - destructive. It can rapidly pinpoint areas that require further laboratory analysis. Environmental Standard Operating Procedures (SOPs) provide guidance on "intelligent sampling" to enhance the accuracy of XRF measurements. Since the introduction of these methods, remarkable progress has been made in XRF technology and data analysis software. These advancements have expanded the element detection range, lowered the detection limit, increased the measurement speed, broadened the scope of data analysis, and enhanced the user experience. As a result, they strongly support the effective assessment and management of soil and plant health.
