Standards were created by volumetric dilution departing from a gravimetrically prepared calibration gas mixture composed of 0.3% of n-propane, 0.7% of iso-butane, and 0.8% of n-butane in nitrogen. In the forensic blood sample, the following concentrations were measured: 90.0 ug/L for n-propane, 246 ug/L for iso-butane, and 846 ug/L for n-butane.

Raman spectroscopy studies on n and i-butane were performed at pressures of up to 40 GPa at ambient temperatures using the DAC technique. Normal butane form oil and gas deposits in any kind of rock in any kind of structural position. methane, ethane, propane and n-butane – main compounds of natural gas.

Standards were created by volumetric dilution departing from a gravimetrically prepared calibration gas mixture composed of 0.3% of n-propane, 0.7% of iso-butane, and 0.8% of n-butane in nitrogen. In the forensic blood sample, the following concentrations were measured: 90.0 ug/L for n-propane, 246 ug/L for iso-butane, and 846 ug/L for n-butane.
