Synthetic concentration walkthrough setup, PROV-USER-GUIDE edition 1 draft. Use linearCalibration.v1 for analyte IL-6, concentrations ng/mL and response absorbance, untransformed concentration and response, unweighted and increasing. Use the 96-well measurement rectangle A1:L8 in interpolation-linear.csv. Calibration standard technical replicate pairs: A1-A2 = 1 ng/mL, A3-A4 = 2, A5-A6 = 4, A7-A8 = 8, A9-A10 = 16, A11-A12 = 32. All six levels are reportable calibration standards. Unknown 1: B1-B2 independent replicates 1-2, dilution factor 10. Quality control 1: B3 independent replicate 1, dilution factor 10, expected undiluted concentration 100 ng/mL. Blank 1: B4 technical replicate 1, not a calibration standard. Leave all other cells unassigned. Do not subtract the blank or exclude wells. Use minimum calibration R-squared >= 0.980, three decision decimal places; no other user suitability criteria. These are synthetic demonstration data, not customer qualification evidence.
