Basics of LC/MS (5968-2543E)
Sample Types LC/MS systems facilitate the analysis of samples that traditionally have been difficult to analyze. Despite the power and usefulness of gas chromatography/mass spectrometry (GC/MS), many compounds are impossible to analyze with GC/MS. LC/MS significantly expands the effective analytical use of mass spectrometry to a much larger number of organic compounds. Gas chromatography and GC...
متن کاملSulphide absorbing gas cleaning in the basics of ethanolamines and formaldehyde
Raw material of heavy oil and gas deposits, developed in per Caspian lowland (Orenburg, Astrakhan, Tengiz, Zanazol), is characterized by high content of acid components (H2S, CO2) and sulphoorganic compounds. Under such circumstances the importance of industrial mining and development of new, economical and wasteless technologies, providing full and experienced usage of all raw compounds being ...
متن کاملQuantitative Determination of LPG Hydrocarbons by Modified Packed Column Adsorbent of Gas Chromatography Via Full Factorial Design
In this study, a new silica gel based adsorbent was fabricated and its ability in separation and quantification of alkanes mixture was investigated. Silica gel (SiO2) is a polar absorbent which is mainly used to separate polar compounds. Also, the carbon materials such as activated carbon and recently carbon nanotube (CNTs), have been widely used for separation of nonpolar materials. Carbon nan...
متن کاملSeparation of Aromatic and Alcoholic Mixtures using Novel MWCNT-Silica Gel Nanocomposite as an Adsorbent in Gas Chromatography
The separations of alcohols with hydrophilic and hydrophobic parts, and the separation of aromatic mixtures, are extremely important processes in gas and petroleum industries. Choosing an adsorbent for performing this separation is the most important part of the process. Silica gel is used as an adsorbent is various techniques such as pressure swing adsorption (PSA) and gas and liquid chromatog...
متن کاملDetermination of 2-phenylethanol in Rose Water Using Dispersive Liquid-Liquid Microextraction with Gas Chromatography Flame Ionization Detection
A simple and rapid microextraction procedure based on dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-flame ionization detection (GC-FID) was developed for the extraction and analysis of 2-phenylethanol in rose water sample. In the proposed approach, carbon tetrachloride and ethanol were used as extraction and dispersive solvents, respectively. Some important pa...
