Results below the limit of quantification are reported as less than the limit of quantitation.  Limit of quantitation: 10 x s  s = standard deviation obtained from nine replicate measurements.  Acetone: 10 x 0.01 = 0.1% (weight/weight) Methanol: 10 x 0.01 = 0.1% (weight/weight) Toluene: 10 x 0.01 = 0.1% (weight/weight)
Les résultats sous la limite de quantification sont rapportés comme étant inférieur à la limite de quantification.  Limite de quantification: 10 x s  s= écart type obtenu à partir de 9 analyses répétées.  Acétone: 10 x 0,01 = 0,1% (poids-poids) Méthanol: 10 x 0,01 = 0,1% (poids-poids) Toluène: 10 x 0,01 = 0,1% (poids-poids)
