Trace organic analysis is for organic compounds present at or below the part-per-thousand level in a sample. The analysis provides the identity (qualitative result) and the amount (quantitative result).Organic chemistry is the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds, which include not only hydrocarbons but also compounds with any number of other elements, including hydrogen (most compounds contain at least one carbon–hydrogen bond), nitrogen, oxygen,Organic chemistry is a branch of chemistry that studies the structure, properties and reactions of organic compounds, which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula.Organic chemistry is the scientific study of the structure, properties, composition, reactions, and synthesis of organic compounds that by definition contain carbon. ... Organic compounds are molecules composed of carbon and hydrogen, and may contain any number of other elements.
Alpha utilizes a multi-level approach to minimizing analytical inteferences for trace organics analyses in challenging matrices. The first stage of interference minimization begins with our choice of extraction procedures. Alpha utilizes a micro-scale extraction procedure or a shaker table method for organics analyses. Both these approaches maximize analyte recoveries while minimizing the impact of the sample matrix. Then, depending on the analysis and the project-specific requirements, the extracts can be cleaned up with gel permeation chromatography, or column chromatography utilizing florisil, silica gel or alumina. PCBs can also be cleaned up with sulfuric acid to remove organics and with copper to minimize sulfur content in the extract. Alpha also incorporates a procedure to minimize the impact of excess moisture content in sediments by determining total solids content prior to extraction, and adjusting the raw extraction weights, if possible.
