Organic chemistry is a chemistry subdiscipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical and chemical properties where it uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behaviour of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivities of individual organic molecules, both in the laboratory and via theoretical (in silico) study.
The range of chemicals studied in organic chemistry includes hydrocarbons (compounds containing only carbon and hydrogen), as well as myriad compositions based always on carbon, but also containing other elements, especially oxygen, nitrogen, sulfur, phosphorus (this are included in many organic chemicals in biology) and the radiostable elements of the halogens. Since organic compounds often exist as mixtures, a variety of techniques has been developed to assess purity. This technique includes High Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC). It also includes the traditional methods of separation such as distillation, crystallization and solvent extraction.
Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention on the stationary phase, thus changing the separation. CORE Laboratory can perform routine analysis which includes Volatiles (i.e., BTEX), Semi Volatiles, Phenols, Alcohols and Total Petroleum Hydrocarbons (TPH). We can also perform “Library Search” analysis for Volatile Organic Compounds (VOCs) and Semi-Volatile Organic Compounds (SVOCs) by Gas Chromatography-Mass Spectrometry (GC/MS). Our capabilities are increasing all the time as we strive to include all parameters that arise from the necessities and specific needs of our clients. Our staff includes highly trained analysts and chemists to meet the demands of complex organic sample analysis and achieve the turnaround times needed in today’s world. Our instrument includes GC with Flame Ionization Detector (FID), GC with Headspace and GC with Mass Spectrophotometer.
