The aliphatic hydrocarbons were measured using a Shimadzu 2014 gas chromatograph with flam ionization detector (GC-FID) operated in splitless mode (1 ul).
Calibration standards were run at the beginning of each working day before each sample batch to establish the calibration curves for aliphatic mixture.
The method detection limit (MDL) was determined as the concentration of individual aliphatic standard in a sample giving a peak with a signal-to-noise (S/N) and ranged from 0.01-0.05 ppm [15].
The concentrations of total aliphatic hydrocarbons (TAH) (including resolved aliphatic (rAH), isoprenoid (Pristane and phytane) and unresolved complex mixture (UCM)) were ranged between 2.18 and 492 ppm dry weights (Fig.
The addition of steam caused some of the organic material that remained in shale during retorting in a nitrogen atmosphere as heavy material by the aromatisation of the oil to produce oils which contain more aromatics and less aliphatics.
This could be a result of the steam reactions which could have caused an increase in the aliphatics degradation (cracking).

[2] reported the content of aliphatic and aromatic hydrocarbons in shale oil produced at a pyrolysis heating rate of 5[degrees]C [min.sup.-1].
Epoxies cured with these products reportedly have at least double the toughness, flexibility, and thermal-shock resistance obtained with aliphatic amines and polyamides.
Armocure aliphatic polyamines provide flexibility, water resistance, solvent resistance, and low viscosity in casting and coating, and also recommended for laminating.
Broad line of epoxy hardeners and catalysts offered, including aliphatic polyamines, aliphatic and aromatic polyamine adducts, anhydrides and polyamides.
Included are aliphatic amine compounds such as D.E.H.
Therefore, we estimated internal doses of aliphatic and aromatic HCs from solvents and fuels in mixed-exhaled breath samples collected from 63 participants.
We analyzed the samples in two batches and quantified aliphatic [C.sub.6][H.sub.14]-[C.sub.16][H.sub.34] ([C.sup.6]-[C.sub.16]) and aromatic (BTEX) HC levels as area under the curve (AUC) for all 63 samples.
We assigned the duplicate, end-of-shift breath sample levels from the 13 participants to the same aliphatic HC and BTEX exposure groups (high/low) approximately 70% of the time, indicating relatively high comparability among samples.
