Non-Destructive XRF vs. Traditional Fire Assay & Acid Test
Why leading Indian gold refiners, hallmarking centers, and jewelry manufacturers are replacing destructive fire assays and acid tests with zero-loss KaratVision non-destructive XRF spectrometry.
Traditional / Destructive
Fire Assay (`IS 1418 Cupellation`) & Acid Test
Involves scraping, cutting, drilling, and dissolving physical gold or silver in hazardous boiling acids (Aqua Regia / Nitric Acid) under BIS IS 1418 destructive cupellation procedures.
- Physical Metal Destruction: Consumes 250 mg to 1.0 gram of actual precious metal per test during lead cupellation. In a busy shop testing 50 samples/day, grams of gold (`Au ~19.32 g/cm³`) are turned to slag or lost in acid waste.
- Time Consuming (2 to 4 Hours): Requires lengthy high-temperature melting, cupellation with lead foil, nitric acid parting, and precision analytical balance weighing before results are known.
- Hazardous Fumes & Pollution: Generates highly toxic lead smoke during cupellation and nitrous oxide gases (`NOx`). Requires heavy fume hoods, pollution control board permits, and chemical neutralisation.
- Density & Touchstone Deception Risk: Archimedes specific gravity testing (`water displacement`) completely fails when gold (`19.32 g/cm³`) is adulterated with dense Tungsten (`19.25 g/cm³`) or Iridium (`22.56 g/cm³`). Acid touchstone only scratches the outer 5 microns.

The Economic Cost of Karat Inaccuracy in Gold Manufacturing
Without exact XRF analytical feedback, jewelry manufacturers lose substantial profit either through "over-karating giveaway" (excess gold in alloy) or "under-karating hallmarking rejection" at BIS centers.
| Production Scenario | Target Purity (22K) | Actual Pour Purity | Daily Financial Impact (on 500g Daily Volume) | Monthly Financial Impact (26 Days) | Operational Consequence |
|---|---|---|---|---|---|
| Over-Karating Giveaway (No XRF Feedback) | 91.66% (22.00K) | 91.85% (22.04K) | -₹13,775 / Day (0.95g Free Gold Given) | -₹3,58,150 / Month Loss | Severe profit erosion. Manufacturer unknowingly gives away nearly 24.7 grams of pure gold every month to stay "safe" above touchstone limits at real ₹1,45,000/10g rates. |
| Under-Karating Rejection (Touchstone Error) | 91.66% (22.00K) | 91.55% (21.97K) | -₹25,000 / Day (Re-melting & Labor Loss) | -₹6,50,000 / Month Loss | Immediate BIS Hallmarking rejection. Entire lot defaced and sent back for re-melting, incurring heavy labor loss, refining fees, and customer order delays. |
| KaratVision XRF Precision Control | 91.66% (22.00K) | 91.67% (22.00K) | +₹13,775 / Day Preserved | +₹3,58,150 / Month Profit Saved | 100% first-pass BIS Hallmarking approval. Zero gold giveaway, exact melt stoichiometry, and maximized profit margins on every single batch. |

Detection of Hazardous Substances & PGM Adulterants
Protect your brand reputation and prevent financial fraud. KaratVision ultra-high resolution silicon drift detectors isolate overlapping X-ray emission lines to catch hidden, high-density adulterants that specific gravity testing completely misses.
Iridium, Osmium & Ruthenium Contamination
Unscrupulous refiners alloy gold (`~19.32 g/cm³`) with cheaper Platinum Group Metals like Osmium (`~22.59 g/cm³`), Iridium (`~22.56 g/cm³`), and Ruthenium (`~12.37 g/cm³`). Because Osmium and Iridium are denser than pure gold, water touch specific gravity tests fail. KaratVision SDD/FSDD (`<145 eV`) separates Gold L-alpha lines from Iridium/Osmium interference to catch even 0.02% (`200 ppm`) of hidden adulterants.
Tungsten Core & Powder Adulteration
Tungsten (`density ~19.25 g/cm³`) has virtually the exact same specific gravity as pure gold (`~19.32 g/cm³`), making water immersion (`Archimedes principle`) completely blind to tungsten slugs inside counterfeit gold bars and thick chain links. KaratVision's micro-focus tungsten tube coupled with secondary target excitation profiles detects abnormal X-ray absorption ratios, immediately flagging tungsten cores or powder inserts.
Hazardous Allergen Compliance (`REACH & BIS`)
European Union REACH regulations and BIS Hallmarking standards strictly regulate skin-contact jewelry for toxic heavy metals. KaratVision simultaneously screens and quantifies trace concentrations of Lead (`Pb <0.05%`), Cadmium (`Cd <0.01%`), and Nickel release (`Ni`), ensuring 100% legal export compliance and safe jewelry manufacturing.
Advanced Plating & Coating Thickness Measurement
Directly from official KaratVision specifications: measure exact plating thickness in sub-microns alongside underlying substrate composition without scratching or stripping the piece.
Simultaneous Sub-Micron Plating & Core Analysis
Whether verifying gold vermeil over sterling silver (IS 2112) or checking rhodium (`Rh`) flashing on white gold bridal sets, KaratVision's multi-layer fundamental parameter (FP) software decodes X-ray attenuation profiles to output exact micron depth (`0.05 µm to 35 µm`) while simultaneously certifying the base metal alloy.
- Gold Vermeil Certification: Measure top Au thickness over 92.5 Sterling Silver substrate

Technical & Financial Frequently Asked Questions
Common technical questions regarding KaratVision XRF spectrometry, payback timeline, and BIS hallmarking compliance.
What is the difference between PIN (`K2`), SDD (`K3`), and FSDD (`K4`) detector technologies?
Silicon PIN (`Si-PIN`) is our entry-level detector with energy resolution around `<160 eV`, ideal for basic retail purity checks taking 45–60 seconds. Silicon Drift Detectors (`SDD`, `<145 eV`) and Fast SDD (`FSDD`, `<122 eV`) handle up to 10X higher count rates with ultra-low electronic noise, enabling 10–15 second rapid assays and separating complex multi-element overlaps (`like Au vs Ir/Ru`).
How does KaratVision catch hidden Iridium (`Ir`), Osmium (`Os`), or Ruthenium (`Ru`) when touchstone & density testing fails?
Osmium (`~22.59 g/cm³`) and Iridium (`~22.56 g/cm³`) have specific gravities higher than pure gold (`~19.32 g/cm³`), while Ruthenium (`~12.37 g/cm³`) and Tungsten (`~19.25 g/cm³`) mimic or alter density without changing touchstone color. Because water immersion tests fail on these heavy elements, KaratVision's secondary target excitation and ultra-high resolution detector (`<122 eV - <145 eV`) isolate trace X-ray fluorescence peaks down to `200 ppm` (`0.02%`), instantly flagging adulteration without cutting the item.
Can the system measure gold plating thickness over silver (`Vermeil`) or brass without scraping?
Yes. Using our multi-layer Fundamental Parameters (`FP`) algorithm conforming to BIS plating specifications (`IS 2112`), KaratVision penetrates up to 35 microns of top plating to simultaneously output both the exact coating depth (`in sub-microns`) and the precise percentage composition of the underlying core metal.
What maintenance or recurring consumables are required for KaratVision XRF analyzers?
Zero chemical consumables are needed. Unlike fire assays that require lead foil, nitric acid, and cupels, KaratVision operates cleanly on standard `110–240V AC` power (`only 100W consumption`). The Peltier thermoelectric cooling eliminates liquid nitrogen requirements, making maintenance practically zero beyond routine automated software calibration.
Does KaratVision comply with BIS IS 1418 and IS 2112 hallmarking laboratory requirements?
Absolutely. While BIS IS 1418 (`Cupellation / Fire Assay`) remains the official definitive method for gold dispute settlement, KaratVision K3 and K4 Series are specifically engineered to exceed Bureau of Indian Standards (`BIS`) requirements for mandatory, high-precision non-destructive XRF preliminary testing and prohibited element screening across NABL-accredited Assay and Hallmarking Centers (`AHC`) before laser marking, including the latest `IS 2112:2025` (`HUID traceable`) silver specifications.
