Isotopic Verification Thresholds for Blended European and Asian Long Staple Flax Fibre
Stable isotope analysis of isolated alpha-cellulose resolves European and Asian long staple flax blends down to ten percent with high statistical confidence.
Isotopic Fractionation Boundary Shift Quantification in Chemically Processed Fiber Blends across Multi-Stage Scouring
Multi-stage chemical scouring depletes carbon-13 and alters oxygen-18 ratios in bast fiber mixtures, requiring mass-balance correction against isolated alpha-cellulose.
Determining Non-European Fiber Substitution Limits in Transferred Yarn Stocks
Non-European flax fiber substitution in transferred yarn stocks is capped at zero percent for pure European Flax and Masters of Linen claims.
Quantifying Isotopic Analysis Boundaries for Verification of Non-European Flax Fiber Blending in Fabric
Multi-element EA-IRMS testing on extracted alpha-cellulose establishes statistical 95% confidence boundaries capable of verifying 15% non-European flax blending.
