Analysis of highly polar compound (ionic liquid) by DART February 23, 2020 7. Organic Synthesis, AccuTOF™ DART®, Application Note, Mass Spectrometry (MS) 0 Introduction Direct analysis in real time (DART™) is applicable to a wide variety of samples; from low polar to highly polar compounds. Ionic liquids have drawn much attention from various engineering fields, such as tribology, because of their unique properties of electrical conductivity, extremely low vapor pressure, low viscosity, low combustibility, etc. The sample was analyzed by dipping a glass rod to the sample and presented it directly to the DART™ ion source.

This application note introduces the example of the analysis of low polar compounds. Analysis of an Ionic Liquid by Using Field Desorption (FD) Ionization Ionic liquids are liquids that are predominantly comprised of ions and ion-pairs. More recently, this term has generally referred to salts that are in a liquid state at room temperature. Ionic liquids are electrically conductive and have an extremely low vapor pressure. Additionally, many of these liquids have low combustibility and excellent thermal stability. As a result of these properties, ionic liquids are expected to find many applications as functional materials. Analyzing a Specific Component using Group Analysis of msFineAnalysis Ver. 2 - MSTips 303 In 2018, we announced the msFineAnalysis software which was designed to automatically integrate two types of data acquired by EI and soft ionization. Recently, we developed msFineAnalysis Version 2, an enhanced version with additional features. msFineAnalysis Version 2 incorporates two new features: Chromatographic Deconvolution and Group Analysis. In this work, we use the group analysis capabilities of the software to evaluate the pyrolysis GC-MS results for a vinyl acetate resin. Integrated Analysis of an Acrylic Resin using msFineAnalysis v2 - MSTips 300 In 2018, msFineAnalysis Ver.1 software was released in which data acquired by EI, soft ionization, and accurate mass measurements were automatically integrated to generate a qualitative report for samples measured by these techniques with GC-MS. Recently, msFineAnalysis Ver.2 was introduced as an enhanced version with additional features. In this work, we will describe the changes in Ver.2, which now includes chromatographic deconvolution, and present applications using the new features. DART Contamination Resistance: Analysis of Compounds in Saturated Salt and Buffer Solutions DART provides very simple mass spectra that are free of multiple charging and alkali metal cation adducts such as [M+Na]+ and [M+K]. This facilitates identification of target compounds in mixtures and simplifies assignment of elemental compositions for unknowns. Integrated Analysis of Fatty Acid Methyl Esters using msFineAnalysis v2 - MSTips 301 Fatty acid methyl esters (FAMEs) are crucial for determining the fat content in food. Being environmentally friendly, they are also increasingly used as bio-diesel fuels. Many of the FAMEs are unsaturated with double bonds in the alkyl chains. As the number of double bonds increases (more unsaturation), the EI measurements tend to lack molecular ions. In this work, we measured a standard sample containing multiple FAMEs using EI and FI to detect their molecular ions. The resulting data was further examined by using msFineAnalysis to produce an integrated report for these compounds in which the library database search was combined with the molecular ion exact mass analysis to produce a qualitative identification of these compounds.
