Supported Liquids & Detection Matrix

PurityScan verifies liquid integrity through non-contact 650 nm transmission attenuation (Beer-Lambert law) and 45°–90° lateral scattering (Rayleigh-Mie theory). Below is the comprehensive classification matrix.

Tested & Compatible Household Fluids

• Fully Supported

  1. Dairy & Emulsions (Fresh & Packaged Milk)

  Emulsions contain natural micellar proteins and suspended fat globules. Any disruption of this colloidal balance alters the lateral scatter signature.

  Detected AdulterantsDetergent / soap surfactants, excessive water dilution, starch, urea frothing agents, unrefined palm oil.

  Optical SignatureDetergents cause micellar fragmentation, driving an acute spike in S2 (lateral scatter). Excess water alters baseline S1 transmittance.
• Fully Supported

  2. Edible Cooking Oils (Mustard, Olive, Sunflower)

  Pure edible oils possess a defined refractive index and specific optical density profiles at 650 nm.

  Detected AdulterantsCheap mineral oils, adulterant argemone oil cuts, unauthorized colorant dyes, synthetic bulk thinners.

  Optical SignatureIndustrial dye cuts and foreign hydrocarbons shift direct beam transmission (S1), while micro-suspended particulates trigger S2 scatter.
• Fully Supported

  3. Natural Honey & Heavy Syrups

  Pure honey exhibits high optical density and consistent solute transparency under focused laser beams.

  Detected AdulterantsInvert sugar syrup dilution, high-fructose corn syrup (HFCS), excess moisture/water blending.

  Optical SignatureMoisture dilution increases direct transmission (S1); unrefined corn syrup creates micro-turbidity that elevates S2.
• Fully Supported

  4. Drinking Water & Municipal Supply

  Clean water provides minimal scatter and maximum 650 nm transmission, serving as an optimal baseline.

  Detected ContaminantsSuspended pipe rust (colloidal iron), micro-algae, clay/silt runoff, trace surfactant/detergent contamination.

  Optical SignatureS1 direct transmission drops according to particulate concentration; S2 immediately registers lateral Rayleigh-Mie scattering.
• Fully Supported

  5. Packaged Vinegar & Clear Fruit Juices

  Standardized acidic solutions and refined juices maintain uniform chromophore density.

  Detected AdulterantsSynthetic chemical dyes, clouding agents, non-standard water dilution, suspended particulate haze.

  Optical SignatureDirect absorbance drops along the 650 nm optical axis (Beer-Lambert attenuation) when color additives or particulate clouds are introduced.

Theoretical Boundaries & Unsupported Fluids

• Unsupported by Design

  Clear Homogeneous Molecular Solutions

  PurityScan cannot differentiate dissolved ionic salts or clear alcohol when mixed into pure water.

  ExamplesSodium chloride (table salt) solutions, clear ethyl alcohol / ethanol dilution, pure dissolved sugar solutions.

  Physical ReasonSalt and alcohol form true molecular solutions rather than colloidal suspensions. They have zero chromophore absorption at 650 nm and produce no particle scattering. At 0° normal beam incidence, refractive changes do not bend the beam.
