GC/MS Analysis of Gasoline Courtney Richardson Dr. Anne Gaquere Chemistry Department Abstract Three different octane levels of gasolines have been gathered from five different gas stations. In a previous experiment, their heat of combustion results have been determined. The goal of this project is to determine if there are any detectable similarities or patterns between these different types and suppliers of gasoline. Gas Chromatography accompanied by Mass Spectrometry

Ass Analytical chemistry What is Qualitative Analysis? Qualitative analysis is the aspect of analytical chemistry dealing with the identification of elements or compounds in an unknown substance. Very simply put, it answers the question "What is in this sample?" and usually does so with yes/no question. What is Quantitative Analysis? Quantitative chemical analysis is the aspect of analytical chemistry dealing with determining the quantity of a particular chemical is in a substance. In short

Cesium iodide and Alkyl metals salt clusters (Na, K, Rb…. Acetates,), with wide m/e range are commonly used for calibration of mass spectrometers. Polymers as poly ethylene oxide or polypropylene oxide are other excellent calibrators. Dish washing compound lauryl sulfate ethoxylorte, is a good calibrator for the compound for negative ion ESI. Water cluster is another good reference standard, with closely spaced reference peaks the other reference compound used are cesium salt of mono butyl phthalate

Question: Give examples of how OLAP works and its Predictive Analytics INTRODUCTION On-line analytical Processing (OLAP) refers to a computer-based processing with a capability of manipulating and analyzing large volumes of data from multiple perspectives (different points of view). It is one technique you can use to transform data into information. The original system of the OLAP is also known as the multi-dimensional cube or hyper cube. For example, a user can request that data be analyzed
