Handheld XRF, LIBS & Vis-NIR Analyzers for Soil Organic Carbon & Agricultural Analysis
Soil organic carbon (SOC) can now be measured rapidly and accurately in the field with SciAps handheld LIBS — no spectral soil libraries, chemical pre-treatment, or lab conditions required. As interest in soil health and carbon sequestration grows, SciAps makes it practical to understand how SOC changes over time and across practices, right where the soil is. This page covers the SciAps analyzer used for agricultural soil carbon, how it works, and related capabilities.
Why Agricultural & Soil-Health Teams Choose SciAps
Traditional SOC measurement means sending samples to a lab and waiting. SciAps handheld LIBS delivers results in the field using a robust, multi-soil calibration — so growers, agronomists, and carbon programs can measure more sites, more often.
Handheld XRF
Fast, non-destructive screening of heavy-metal contaminants (As, Pb, Cd) and nutrient elements in seconds, with no sample digestion.

Measures total organic carbon in soil directly in the field — no spectral libraries, chemical pre-treatment, or lab conditions required.

Beyond soil carbon, handheld XRF adds fast, non-destructive screening of the metals that matter for food safety and soil fertility — heavy-metal contaminants like arsenic, lead, and cadmium, plus nutrient-related elements (K, Ca) and micronutrients (Fe, Mn, Zn, Cu). Results come in seconds, in the field, with no sample digestion — and where cadmium has to be measured to a regulatory limit rather than screened, the X-555 takes it further.
Lowest Cadmium Detection Limits
The world's most powerful handheld XRF, and the only one with a 55 kV tube, the X-555 delivers the best detection limits available on cadmium — plus the rest of the higher-atomic-number RCRA and EPA Priority Pollutant metals (barium, tin, antimony, silver). The choice when contaminant work in soil, feed, or crop material has to stand up to a regulatory threshold rather than a field screen.
The Analyzer for Soil Organic Carbon
Rapid In-Field SOC Measurement
Smaller and lighter than ever, the Z-903 handheld LIBS measures total organic carbon in soil directly in the field. The SOC calibration was built with the Agricultural Laboratory Proficiency (ALP) program from a diverse set of U.S. and Canadian soils spanning pasture, fallow, forest, corn, grains, potatoes, soybeans, fruits, rice, and cotton — so a single standard calibration delivers fast, accurate SOC across soil types.
Vis-NIR for Crop, Soil & Food Analysis
Near-infrared spectroscopy is a foundational technique in agriculture and food science — and SciAps Vis-NIR instruments bring it to the field and lab. Where LIBS and XRF measure elements, Vis-NIR reads molecular (O-H, C-H, N-H) features to characterize composition and quality without reagents or sample destruction.
FieldSpec, TerraSpec & LabSpec
The ASD FieldSpec, TerraSpec, and LabSpec spectroradiometers (350–2500 nm) are long-established tools for agricultural and food analysis — soil organic matter, moisture, and texture; crop and vegetation health (nitrogen, chlorophyll, stress); and food and feed composition and authentication (protein, fat, moisture, adulteration screening). FieldSpec suits outdoor crop and soil work; LabSpec suits controlled food/feed lab settings.
Software & Data Management
Built on Android, SciAps analyzers send every test via Wi-Fi to one or more PCs anywhere in the world, with real-time syncing, custom auto-generated reports (your logo and layout), and secure cloud storage. Share results to a phone via Bluetooth for instant PDF emailing, print to Wi-Fi or belt-mounted Bluetooth printers, and automatically merge LIBS and XRF data — even a competitor's XRF — into a single report.
SciAps Cloud+ takes Vis-NIR beyond simple field measurements, turning every scan into real-time, actionable intelligence. It connects lab-grade calibration, field instruments, and cloud-based insights in one scalable platform—so you can measure more, see more, and make confident decisions faster.
Frequently Asked Questions
Can you measure soil organic carbon without a lab?
Yes. The SciAps Z-903 handheld LIBS measures total organic carbon in soil directly in the field — no spectral soil libraries, chemical pre-treatment, or lab conditions needed — using a calibration built from a diverse set of U.S. and Canadian soils.
How does handheld LIBS measure carbon in soil?
LIBS fires a laser that ablates a tiny amount of soil into a plasma and reads the emitted light; the deep-UV carbon line requires on-board argon purge to reach the needed sensitivity. The Z-903 also rasters the laser across the sample (X/Y) for a representative reading and uses an integrated camera for positioning.
Why measure soil organic carbon in agriculture?
SOC is a core indicator of soil health and a key metric for carbon-sequestration programs. Measuring it quickly and repeatedly in the field lets growers and agronomists track how carbon changes over time and across management practices, without lab turnaround.
Which soil types does the SciAps SOC calibration cover?
The calibration was developed with the ALP program from soils across the U.S. and Canada spanning many usage sites — pasture, fallow, forest, corn, grains, potatoes, soybeans, fruits, rice, and cotton — so one standard calibration works across diverse soil types.
Can I screen agricultural soil for heavy metals like arsenic and lead?
Yes. SciAps handheld XRF (the X-505 and X-50) screens soils for heavy-metal contaminants such as arsenic, lead, and cadmium — plus nutrient elements like K and Ca and micronutrients — in seconds, with no digestion. For the lowest detection limits on cadmium and the full RCRA / Priority Pollutant metal suite, the X-555 is the environmental-grade option.
