%X The
determination of the ethanol content in food products is of fundamental
importance for HALAL certification. In this work, an analytical method for the
determination of ethanol in water by headspace gas chromatography with flame
ionization detector (HS-GC-FID) has been developed and validated for <span>the use in characterization of ethanol reference
materials. The validation study</span> was carried</span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">out in
the linear calibration range 100</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">-</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">1500
mg/kg using the NIST SRM 2900, nominal 95.6%. The studied performance
characteristics of the method were the limit of detection, LOD, the limit of
quantification LOQ, <span>selectivity, linearity,
precision, recovery and bias. The validation results showed</span> that the
method is selective, precise, accurate and free from any significant <span>bias. The LOD and LOQ were 1.</span></span></span></span><span><span><span style=\"font-family:&quot;\">27</span></span></span><span><span><span style=\"font-family:&quot;\"> and </span></span></span><span><span><span style=\"font-family:&quot;\">3.86</span></span></span><span><span><span style=\"font-family:&quot;\"> mg/kg respectively and the estimated</span></span></span><span><span><span style=\"font-family:&quot;\"> expanded uncertainty was 2% indicating that the method is fit</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">for</span></span></span><span><span><span style=\"font-family:&quot;\"> </span></span></span><span><span><span style=\"font-family:&quot;\">the
