应用气相色谱质谱法对文物中天然有机胶合材料的研究(英文版) 内容简介
用于装饰目的的颜料可以追溯到4万年前，当时史前人类用绘画和素描装饰洞穴。古时候可用油、树脂、阿拉伯树胶、明胶、蛋清、蜂蜡等作为黏结剂。显然，这些有机材料在艺术目前起着很好重要的作用，因此，对其进行明确的识别和更好地了解其退化机制，对于保护文化遗产至关重要。本书中研究了GC/MS和Py-GC/MS技术来鉴定艺术品中应用，并以案例形式介绍了其使用方法

Chapter 1 Introduction to gas chromatography and mass spectrometry 1.1 Gas chromatography Gas chromatography is a technique used to separate mixtures of gaseous chemical compounds based on differences in the compounds’ relative affinities for a solid (gas-solid chromatography) or liquid (gas-liquid chromatography) stationary phase held within a column. The main part of a gas chromatography is the column. It has a gaseous mobile phase or eluent that carries the solute or sample through the stationary phase where the separation occurs. The carrier gas (gaseous mobile phase)， usually helium， nitrogen， or hydrogen， transport the sample to the stationary phase. In the terms of the intermolecular forces， an interaction occurs between the sample molecules and the stationary phase molecules. The intensity of interaction differs from strong to weak. The stronger the interaction， the longer the sample retained in the stationary phase， ensuring the successful separation of the mixture [1]. Figure 1.1 illustrates the sample (mixture) interaction with stationary phase. 1.2 Mass spectrometry Mass spectrometry is an analytical technique that uses an instrument called a mass spectrometer to measure the mass-to-charge ratios of molecular ions. Molecules fragment within the mass spectrometer to produce a mass spectrum， which can be interpreted to determine the identity of the molecules in the sample. A mass spectrometer is commonly composed of ion source， mass analyzer and detector. Firstly， the sample molecules are ionized by ion source into gas-phase ions which are then transported to the mass analyzer in magnetic or electric field. Then the mass analyzer sorts the ions by their mass-charge ratios in the electromagnetic field. Finally， the detector converts ions into electrical signals which are shown in software in the form of spectrum (Figure 1.2). The three main parts of MS instrument work in a vacuum system. When the pressure of the instrument is high， the density of gas is high， and the probability of collision between ions is high. The collision will make the ions deviate from the normal motion orbit. Only under low pressure， the ions will have enough average free paths， and there will be no collision between them. The vacuum system ensures that ions move in the normal orbit from the ion source to the detector， and ensure the good focus of the ion beam， so that high sensitivity and resolution of the MS instrument can be obtained. Mass spectrometer usually uses two-stage exhaust system. The first stage pump is usually the molecular turbine pump， which is to pump out the carrier gas from GC and remain a high vacuum state in mass spectrometer. The second stage pump is usually a mechanical pump， which can discharge the gas extracted from the first stage pump. Figure 1.2 The components of mass spectrometer and illustration of its working path 1.3 The Components and functions of GC/MS GC/MS is mainly composed of gas chromatograph， mass spectrometer， mechanical pump and personal computer system (PC) [2]. Gas chromatograph has a high efficiency of separating a variety of compounds and obtaining a single substance. Mass spectrometer can effectively identify an unknown compound with a high sensitivity， but it requires a single sample. Their combination enables the qualitative and quantitative analysis of complex organic materials in many fields (Figure 1.3) Figure 1.3 The main components of GC/MS 1.3.1 Ion source There are many kinds of ionization technologies， including electron ionization (EI)， chemical ionization (CI)， electrospray ionization (ESI)， matrix-assisted laser desorption/ ionization (MALDI)， field desorption (FD)， fast atom bombardment (FAB)， thermospray， desorption/ionization on silicon (DIOS)， direct analysis in real time (DART)， atmospheric pressure chemical ionization (ACPI)， secondary ion mass spectrometry (SIMS)， spark ionization and thermal ionization (TIMS) [3]. EI is the common ionization technique for gases and vapors. In EI mode， the sample molecules are bombarded by electrons with certain energy (generally 70 eV)， and lose their own electrons， then become molecular ions which can be used to determine the molecular weight of the compounds. When the residual energy of molecular ions is greater than some chemical bonds energy， they break up and form fragment ions， which can be used to determine the structure of the sample molecules. EI has an advantage of nonselective ionization. As long as the sample can be gasified， it can be ionized with high efficiency and sensitivity. Other ionization techniques， such as ESI and MALDI are also commonly used for their high efficiency for analyzing biomaterials [4]. 1.3.2 Mass analyzer The sector instruments of a mass analyzer include time-of-flight analyzer， quadrupole mass filter， ion traps， Fourier transform ion cyclotron resonance， etc. 1.3.3 Detector The detector records the charge induced
