The use of Raman spectroscopy for routine quantitative analysis is desirable due to the simple sample handling requirements for sample analysis. Due to the many variables associated with Raman spectroscopy, specifically,

Laminates are combinations of polymers that combine the benefits and properties of the various polymers used in the laminate to create a better material. Polymer laminates have a multitude of uses including packaging for food and other products. Laminates act as moisture and/or oxygen barriers and as such are commonly used to protect foods and chemicals. Analysis of laminates is often required for quality control and to determine laminate adhesion problems.

Mass directed fraction collection for preparative SFC

Introduction Gasoline is produced by fractional distillation of petroleum at a boiling point between 30°C and 200°C. It contains hydrocarbons such as paraffin, olefin, and aromatics, carbon numbers of which are between 4 and 10. Characterization of gasoline requires the determination of the contents of those hydrocarbons. American Society for Testing and Materials (ASTM) announced a method, D6550-00: Standard Test Method for Determination of Olefin Content of Gasolines by Supercritical-Fluid Chromatography. We have established an analysis system in accordance with this method.

Introduction Diesel fuel is a complex mixture of hydrocarbons including non-aromatic, mono-aromatic and polyaromatic hydrocarbons. It is well known that the composition of these compounds is closely related to the cetane number of fuel in the way that the cetane number becomes higher as the concentration of nonaromatics increases. The number becomes lower and the amount of particulate matter in exhaust gas increases as the concentration of aromatics increases. The analysis of diesel fuel is taking an important role in the automobile and fuel industries. ASTM (American Society for Testing and Materials) published the “Standard Test Method for Determination of the Aromatic Content and Polynuclear Aromatic Content of Diesel Fuels and Aviation Turbine Fuels By Supercritical Fluid Chromatography (D 5186 – 03)” using a Flame Ionization Detector (FID) in 2003 1). This application note demonstrates that SFC with supercritical CO2 can determine the non-aromatic and aromatic contents in commercially available diesel fuel in accordance with the ASTM method.

Even though Supercritical Fluid Chromatography (SFC) was first demonstrated by Klesper et al. in 1962, 6 – 7 years earlier than High-Performance Liquid Chromatography (HPLC), its history is unfortunate and it has never been a main stream of chromatography. Why?Partly because an automated liquid chromatograph (LC), namely, an amino acid analyzer by Spackman, Stein and Moore, had already been commercially available in the late 1950’s and there were actual needs for LC, while therewere no such needs for SFC except for some exotic samples such as metalloporphyrins and metallic chelates at that time. Rapid development of HPLC occurred in the 1970’s overshadowed the development of SFC taken place at the same time. However, there are remarkable research works done in the 1960’s, the 1970’s and the 1980’s that realized the today’s modern SFC, and this poster will review these works.
