Overview

EN ISO 20714:2021 / ISO 20714:2019 specifies a validated analytical procedure for quantifying nicotine, propylene glycol (PG) and glycerol in e-liquids used with electronic nicotine delivery devices (ENDDs) using a gas chromatographic method (GC-FID). The standard defines sample preparation, required reagents and apparatus, calibration practice, chromatographic conditions, and reporting to ensure consistent, comparable results across testing laboratories.

Key topics and technical requirements

Scope and principle

Quantification by capillary gas chromatography with flame ionization detection (GC-FID) using internal standards.

Reagents and standards

High-purity carrier/auxiliary gases (helium or hydrogen; FID hydrogen and air).
Solvent: isopropanol (≥99%) for dilution.
Reference substances: nicotine (≥98%), propylene glycol (≥99%), glycerol (≥99%).
Internal standards suggested: quinaldine, 1,3-butanediol, n‑heptadecane, n‑octadecane (users may assess alternatives).

Calibration

At least five calibration solutions covering expected analyte ranges (example ranges used in the collaborative study: nicotine 0.005–1.5 mg/ml; PG and glycerol 0.12–10 mg/ml).

Apparatus and column

Capillary GC with FID; DB‑ALC1 (30 m × 0.32 mm ID, 1.8 µm) cited as satisfactory. Alternative columns allowed if resolution is adequate.

Sample handling and procedure

Typical test portion: 0.100 g sample diluted with 10 ml isopropanol/internal standard solution; equilibrate to room temperature; store extracts at 2–8 °C if necessary.
Example GC conditions provided (oven temperature program, injection volume 1 µl, split 50:1, helium carrier 1.8 ml/min, detector/injection temperatures).

Quality

Monitor internal standard peak consistency; perform repeatability and reproducibility assessments and report results per the standard.

Practical applications

Routine laboratory testing for e-liquid composition and quality control.

Regulatory compliance testing and product labelling verification (nicotine strength claims).

Research and product development (formulation verification, stability studies).

Forensic and public health labs assessing exposure potential from ENDD products.

Who should use this standard

Analytical and contract testing laboratories performing e-liquid analysis.

E-liquid and electronic cigarette manufacturers implementing QC procedures.

Regulatory authorities and notified bodies overseeing product safety and compliance.

Research institutions studying aerosol chemistry and nicotine delivery.

Related standards and references

ISO 13276 (noted in EN ISO 20714 for verifying nicotine purity).

Developed by ISO/TC 126 (Tobacco and tobacco products) and adopted by CEN/TC 437 (Electronic cigarettes and e-liquids).

Keywords: EN ISO 20714, ISO 20714, e-liquid analysis, gas chromatographic method, GC‑FID, nicotine determination, propylene glycol, glycerol, e-liquids testing, electronic nicotine delivery devices.
