The concentrations of n-decane and n-tetracontane may vary slightly from batch to batch. According to DIN EN ISO 9377-2, the prescribed concentration is approximately 20 mg/L in heptane for n-tetracontane and approximately 15 mg/L in heptane for n-decane. This standard is primarily used for identifying the gas chromatography retention time window for hydrocarbons between n-decane and n-tetracontane, and the exact concentrations are not quantified for each batch.
