Is the Vanta Core Right for Your Work?
The Vanta Core is the right choice if:
- You need high-performance RoHS screening across a wide range of materials including complex polymers, alloys, platings, and mixed-matrix assemblies
- Your work includes small components, densely populated circuit boards, or individual solder joints where precise beam placement matters
- You want the option to add a 3 mm collimator for targeted analysis of small parts without switching to a different instrument
- You need Work Station compatibility for benchtop or closed-beam sample staging
- Your compliance program requires IP55 dust and water jet protection for manufacturing floor or warehouse environments
- You need strong test-to-test repeatability and instrument-to-instrument consistency across a compliance team
Consider the Vanta Element-S instead if:
- Budget is a stronger driver and your screening is primarily standard RoHS jobs at typical thresholds without a need for collimation or desktop work station operation
Consider the Vanta Max instead if:
- You need the lowest limits of detection for these elements

What Sets the Vanta Core Apart for RoHS
8-Position Filter Wheel for Optimized Multi-Beam Analysis The Vanta Core runs an 8-position autoselected filter wheel - the same configuration as the top-of-line Vanta Max and a significant step up from the 4-position wheel on the Element-S. With eight filter positions available per beam per mode, the Core can optimize signal-to-background ratio independently for each element group across the full RoHS screening sequence. This produces faster, more precise results across the widest range of material types and restricted substances without operator input.
Add the 3 mm Collimator for Small Component Work The Vanta Core supports optional collimation to a 3 mm diameter beam spot - one of its most important differentiators for RoHS work on electronics. Standard handheld XRF beams of 6 to 8 mm can overlap adjacent components, solder joints, or substrate material on a populated circuit board, averaging surrounding materials into the result and potentially masking a non-compliant reading. The 3 mm collimator reduces the beam to target individual solder joints, SMD components, connector pins, and component leads with precision. This level of targeted analysis was previously only achievable with benchtop XRF instruments. The collimator is a factory-installed hardware accessory and must be specified at time of order.
Vanta Work Station Compatible The Vanta Core is fully compatible with the Vanta Work Station - a battery-operated portable benchtop enclosure with a fully interlocked lid and 360-degree shielding. The Work Station allows operators to stage small or irregularly shaped samples, circuit boards, and components in a stable, reproducible position for longer or repeated measurement sequences. Results are more consistent when sample position is fixed, which matters especially when working near regulatory thresholds or building a statistically valid screening program. The Work Station can be operated via Vanta PC software or the Vanta mobile app while the operator attends to other tasks.
4W X-Ray Tube at 50 kV with Silver or Rhodium Anode The Vanta Core runs a 4-watt X-ray tube at up to 50 kV with application-optimized anode material - silver (Ag) at 8-50 kV or rhodium (Rh) at 8-40 kV depending on configuration. The silver anode configuration is typically selected for RoHS and consumer product applications. More power and a wider kV range combined with the 8-position filter wheel gives the Core superior flexibility across diverse material types compared to the Element and Element-S.
Axon Technology for Repeatable Results Every Vanta analyzer is built on Evident's proprietary Axon technology. Axon uses ultra-low-noise electronics to enable higher X-ray counts per second, producing fast, accurate, and repeatable results. Test-to-test and instrument-to-instrument repeatability are exceptional - your first measurement and your last are consistent, and results match across multiple Core units if your team runs a fleet. For compliance programs where results near thresholds determine pass, fail, or inconclusive, repeatability is not a secondary concern.
SDD Detector with Graphene Window The Vanta Core uses a silicon drift detector with a high-sensitivity graphene window, providing strong sensitivity across the full range of RoHS restricted substances in both polymer and alloy matrices.
IP55 Rated for Demanding Environments The Vanta Core is rated IP55 - dust protected and protected against low-pressure water jets from all directions. This is a step up from the IP54 rating on the Element and Element-S models, and makes the Core the better choice for environments where water exposure from cleaning, condensation, or outdoor conditions is a real risk.
MIL-STD-810G Drop Tested Drop tested to US Department of Defense MIL-STD-810G standards from 4 feet. Built for manufacturing floors, warehouse receiving docks, and field audit environments.
Solid Detector Shutter The Core includes a solid detector shutter to help prevent detector damage during transport and handling - a hardware protection feature not present on the Element and Element-S models.
Fleet Management and Connectivity The Vanta Core runs on Linux with cloud-enabled fleet manager capability. Custom setups, pass/fail thresholds, and user configurations can be pushed across an entire fleet from a central PC. Wi-Fi and Bluetooth connectivity via optional USB adapter. USB 2.0 ports for data export and accessories.
Warranty and Service Coverage The Vanta Core comes with Evident's standard manufacturer warranty. Confirm current warranty terms at time of order.
What You Can Screen With It
Small Components and Circuit Boards The combination of optional 3 mm collimation and Work Station compatibility makes the Core the strongest RoHS instrument in the Vanta line for circuit board and small component work. Target individual solder joints, SMD devices, connector pins, and component leads with precision. Stage boards in the Work Station for stable, reproducible measurements across repeated samples.
Incoming Component and Material Inspection Screen connectors, cables, housings, fasteners, plated components, and metal parts across a wide range of material types. The 8-position filter wheel handles the full range of incoming material matrices without reconfiguration.
Consumer Products and Toys Screen painted surfaces, plastic parts, metal components, and apparel hardware for lead, cadmium, and restricted substances. Accepted for EU RoHS, WEEE, CPSIA, and ASTM F963 toy safety screening programs.
Supplier Audits At 4.06 lbs with battery, the Core is practical for field use and supplier visits. IP55 protection adds durability confidence in environments where the instrument may be exposed to cleaning agents or outdoor conditions.
Halogen-Free Screening Configure chlorine and bromine screening alongside standard RoHS elements. The 8-position filter wheel includes a dedicated low-energy beam optimized for chlorine detection, making the Core well suited for combined RoHS and halogen-free compliance programs.
Important Accessory Note The Vanta Core is compatible with the Work Station, Field Stand, Soil Foot, Holster, Probe Shield, Hot Heel, and Weld Mask. Optional 3 mm collimation is available and must be specified at time of order. The Work Station and collimator together make the Core the most capable instrument in the Vanta line for small component RoHS screening.
