Resolving and quantifying complex mixtures is, as their name suggests, complex, and we at Consolidated Sciences treat it as an art form. Complex mixtures typically combine multiple techniques on state-of-the-art technology with proper handling and advanced mathematics. Analysis of complex mixtures is also largely dependent on the chemical characteristics of the sample; its reactivity, boiling point, melting point, etc. It is recommended that all complex mixture analyses be discussed directly with an analyst to achieve the best analytical results.

Alcohols

GC‑MS will yield measurements as low as 0.1 ppm of analytes including methanol, ethanol, 1‑propanol, 2‑propanol, acetone, dimethyl ether, diethyl ether, acetaldehyde, acetonitrile, acrylonitrile, 2‑methyl‑1‑butanol, 2‑methyl‑2‑butanol, and 3‑methyl‑2‑butanol.

Amines

GC‑MS will also measure analytes including 2‑(1H‑indol‑3‑yl)‑N,N‑dimethylethanamine, dimethylamine ((CH₃)₂NH), methylamine (CH₃NH₂), n‑methylethanamine, n,n‑dimethylethylamine (C₄H₁₁N), and trimethylamine (NCH₃)₃).

Atmospherics

A variety of methods will yield measurements as low as 0.2 ppm of analytes including argon (Ar), carbon dioxide (CO₂), carbon monoxide (CO), helium (He), hydrogen (H₂), krypton (Kr), methane (CH₄), neon (Ne), nitrogen (N₂), nitrogen dioxide (NO₂), nitrous oxide (N₂O), oxygen (O₂), ozone (O₃), water vapor (H₂O), and xenon (Xe).

Combustion Gas

GC‑TCD and GC‑FID methods can detect analytes in combustion gas including carbon dioxide (CO₂), carbon monoxide (CO), hydrogen (H₂), methane (CH₄), acetylene (C₂H₂), ethylene (C₂H₄), ethane (C₂H₆), 1,3‑butadiene, propyne (C₃H₄), propene (propylene) (C₃H₆), diacetylene, cis/trans‑2‑butenes, 1‑butene, 1,5‑hexadiene, 3‑methyl‑1‑pentene, cyclopentane (C₅H₁₀), 1,2,3‑trimethylcyclopentane (C₈H₁₆), benzene (C₆H₆), ethyl benzene, and hydrocarbons C₇–C₉.
