Agilent 5100 ICP-OES

Fossil fuels have been the main source of energy in industrial applications and transportation for decades. However, depleting reserves, environmental concerns and economic issues have led to the development of renewable, cheaper and cleaner alternatives. Bio-ethanol is one of those alternatives and is derived by fermenting the sugar and starch components of plant byproducts. Different purities of bio-ethanol are used as fuel sources. Hydrated ethanol fuel has not had treatment to remove moisture and contains between 93-96% ethanol. It is often used in flexible (flex-fuel) or dual fuel engines. Anhydrous ethanol has been treated to remove moisture and has a purity of at least 99%. It is blended at up to 25% v/v with gasoline. High purity fuel can be contaminated with elemental impurities during production, stockpiling and transportation, so accurate quantitation of metal content is important. According to ASTM D4806 specification [1] and the Brazilian National Agency of Petroleum, Natural Gas and Biofuels 2 (ANP) Resolution number 19/2015 [2], the presence of Cu, Fe, Na and S in ethanol must be controlled. Limit concentrations for Cu are 0.1 and 0.07 mg/kg (ASTM and ANP respectively), 5 mg/kg Fe (ANP), 2 mg/kg Na (ANP), and 30 mg/kg S (ASTM). In this study, the accuracy, precision and long term stability performance of the Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES was evaluated for the determination of Cu, Fe, Na and S in ethanol fuel samples according to ASTM D4806 and ANP Resolution 19/2015 methods.

Steel manufacturers conduct quality control testing for a range of metals and trace elements to ensure the grade and performance of their final product. The Standardization Administration of China uses their GB/T 20125-2006 standard “Low-alloy steel – Determination of multi-element contents – Inductively coupled plasma atomic emission spectrometric method” to control the quality of manufactured steel products. Different grades of steel have different specifications for elemental content, with most steel and stainless steel grades required to have less than 0.05 % by weight of Sulfur and 0.04 % by weight of Phosphorus. With the Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) technique easily able to measure elements at this concentration within a sample, laboratories are looking beyond whether an instrument can ‘do the job’ to whether a specific instrument can improve their sample throughput, lower their costs, simplify sample preparation and instrument operation, and deliver reliable results throughout the analysis of a large batch of samples. 2 This application note demonstrates the performance and benefits of Agilent’s 5100 Vertical Dual View (VDV) ICP-OES instrument in the analysis of steel samples, using the GB/T 20125-2006 method. The instrument offers many advantages for this application, which involves the rapid analysis of a large number of challenging steel samples.

5100 VDV ICP-OES 非常适用于分析浓盐水。它采用垂直炬管以及在 27 MHz 下运行的固态射频 (SSRF) 系统产生稳定的等离子体，能够处理溶解态固体含量高的溶液并提供长期分析稳定性，且炬管所需的清洁和更换次数较少。本研究对 Agilent 5100 ICP-OES 测定浓盐水中 Ca、Ma、Sr 和 Si 的准确度和稳定性进行了评估。

Trace metals in gasoline are a major source of environmental pollution. They can also adversely affect the performance of automotive engines. Silicon (Si) contamination can be especially problematic as deposits damage components such as catalytic convertors and oxygen sensors leading to costly repairs. ICP-OES is often used for the determination of trace elements in petroleum products due to its reliability, robustness and sensitivity. A successful analysis needs to take account of sample characteristics, such as the high volatility of gasoline. Continuous loading of the plasma with gasoline can affect the stability of the signal and lead to carbon build up on the torch that may cause the plasma to extinguish. 2 In this study, the Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES was used for the analysis of 21 elements in gasoline, including Si. Oxygen was added to the auxiliary argon gas flow to reduce carbon build up on the torch, maintain a stable plasma and reduce carbon emission from the organic solvent. A programmable temperature spray chamber, set to -10 °C, was used to reduce vapor loading on the plasma, ensuring a more stable plasma.

实验室一直都希望能够通过提高样品通量和尽力减少日常费用来提高分析效率并降低运行成本。农业应用实验室通常需要处理大量样品，但提高分析速度通常会导致某种分析性能的损失，例如精密度降低。结合了完全集成式高级阀系统 (AVS) 的 Agilent 5110 ICP-OES 无需在分析速度和精密度之间进行折中。其设计用于实现更快速、更经济而更简单的样品分析，是高通量实验室的理想选择。

水质对各种生态系统的健康有着直接的影响，因此，监测水、废水以及固体废弃物中的污染物极为重要，往往需要受到严格的法规限制。ICP-OES 是一种行之有效的技术，也是许多采用美国环境保护局 (EPA) 方法（尤其是 200.7 法规——使用 ICP-AES 测定水、固体和生物固体中的金属和痕量元素）的环境实验室的主力工具。许多环境实验室每天需处理数百个样品，因此一直期望能够提高分析效率、降低操作成本，同时保持仪器稳定性、易用性和分析性能。

许多从事地下水、工业废水、土壤、污泥和沉积物等环境样品中元素分析的实验室操作 ICP-OES 以美国国家环境保护局 (US EPA) 6010C 方法作为指导原则。这些实验室期望提高样品通量并降低分析成本，但由于元素种类众多且在典型样品中的浓度各不相同，因此使用光谱化学技术难以达到目标。 配备垂直炬管的径向 ICP-OES 或双向观测 (DV) ICP-OES 通常用于测定复杂环境样品中的常量、微量和痕量元素。然而，Agilent 5100 ICP-OES 独特的同步垂直双向观测 (SVDV) 构造能确保仪器在最适合特定应用的模式下运行（轴向、径向、垂直双向观测或同步垂直双向观测），为建立方法和应用要求提供充分的灵活性。 本研究采用在 SVDV 观测模式下运行的 Agilent 5100 ICPOES，依照 6010C 方法对河床污泥有证标准物质中的常量、微量和痕量元素进行了分析。将 Agilent SVS 2+ 切换阀系统与 ICP-OES 配套使用，以提高样品通量并减少每个样品的氩气消耗量。6010C 方法是一套基于性能的指导原则，用于分析土壤、污泥和沉积物中的 31 种元素。6010C 方法要求 5100 SVDV ICP-OES 满足校准有效性、线性动态范围(LDR)、方法检测限 (MDL) 以及光谱干扰检测 (ISC) 的性能标准。

The determination of the elemental composition in plants is important for development, growth and maintenance of plant tissues. Elements, such as Al, B, Ba, Ca, Cu, Fe, K, Mg, Mn, S, Sr, P, and Zn, are important for plant nutrition, being vital nutrients required for tissue development, maintenance and plant metabolism [1]. The determination of macro, micronutrients and contaminants in plant samples is important to keep up with sources of nutrients and minerals. The chemical analysis of plant materials can be applied to assist in the remediation of contaminated soils or to solve mineral malnutrition, a problem that seriously affects the human population [2, 3]. Inductively coupled plasma optical emission spectrometry (ICP-OES) is an attractive technique for this analysis because it can accommodate the wide concentration ranges typical of macro and micronutrients in plants. 2 Agronomical laboratories typically deal with large batches of samples. Several critical elements, in wide concentration ranges, must be determined on a routine basis for such samples. The Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES with Dichroic Spectral Combiner (DSC) technology, has the ability to keep up with these demands, performing axial and radial measurements in a single reading, leading to faster sample throughput times. With faster sample run times, the 5100 SVDV requires less argon per sample, meaning significant savings can be made for labs involved in high throughput analysis. The Vista Chip II detector used in the 5100 ICP-OES has the fastest processing speed (1 MHz) of any charge coupled device (CCD) detector used in ICP-OES. It delivers fast warm-up, high throughput, high sensitivity, and the largest dynamic range.

使用原子光谱分析技术对葡萄酒和烈酒进行元素分析被广泛应用于区分不同的食品和饮料，因为产品中存在的元素根据地理、原材料、生产方法和储存等条件而各有不同。 由于其高灵敏度和广泛的多元素覆盖范围，ICP-MS 已成功 地用于分析其他酒精饮料（如葡萄酒）的元素组成 [2]， 并用于区分不同原产地以及加工地点的葡萄酒 [3, 4]。微 波等离子体原子发射光谱仪 (MP-AES) 也已经用于通过几 种目标元素来分析葡萄酒 [5]。 本研究考察了 Agilent 5100 同步垂直双向观测 (SVDV) ICPOES 分析六种不同类型威士忌的适用性。还利用安捷伦的 Mass Profiler Professional (MPP) 软件对结果进行了分析。MPP 使用户能够以不同的方式显示数据，可以更轻松地对结果进行比较和解析。安捷伦的 5100/5110 ICP-OES 系列仪器提供的数据可通过 MPP 进行分析。本应用也适用于 Agilent 5110 ICP-OES。

"为了保护公共健康和环境，动物性食品产品中各种元素（包括营养元素、微量营 养元素和有毒元素）的测定必须遵守国家或国际监管机构的规定。例如，联合国 粮农组织 (FAO) 和世贸组织 (WTO) 成立了食品法典委员会，制定了统一的国际食品标准、指南和操作规范，各国通常以此为立法的基础。需要遵循监管框架的食 品检测实验室必须在日常分析中监测大量样品的各种指定元素。ICP-OES 仪器以其可靠性和易用性，已广泛用于许多食品检测实验室。不过，Agilent 5100 同步垂直双向观测 (SVDV) ICP-OES 技术的操作水平和性能更胜一筹，尤其体现在它的稳定性、分析速度和较低的运行成本方面。Agilent 5100 使用的 ICP Expert 软件配有包含预设方法模板的软件程序，可快速、简单地进行方法开发。DSC 智能光谱组合技术进一步简化了方法开发，无需针对样品中的元素选择等离子体观测模式。操作人员仅需选择测量元素和波长，仪器会自动完成测量模式的切换，全谱一次曝光，一次分析完成。例如，样品中百分含量水平的营养元素（如钠和钾）可通过垂直观测分析，而 ppm 或 ppb 水平的其他元素（如铜或锌）可在同一次读数中通过水平观测分析，从而实现对宽浓度范围内的所有元素进行分析。仅需对样品进行 1 次测量，而传统双向观测仪器需要 2 次、3 次，甚至 4 次测量。"

牛奶的元素组成能够很好地指示环境的污染情况。牛奶在为人类提供必需元素的 同时，也是有毒金属摄入的重要途径。因此，人们开发了一系列标准方法和指南以监测牛奶及牛奶类产品中的元素含量。例如，中国国家食品安全标准 GB 5413.21—2010 就规定了对婴幼儿食品、原料乳以及乳制品中钙、铁、锌、钠、 钾、镁、铜和锰的测定。奶粉中的许多常量营养元素（如 Na、K 和 Ca）的含量很高。同时还必须测定低浓度的有毒元素，因此仪器的灵敏度至关重要。为了达到有毒元素所要求的低定量限，人们倾向于使用水平观测 ICP-OES 仪器，但同时也必须考虑如何测定高浓度的常量营养元素。以往研究 表明，向标样和样品中添加铯 (Cs) 内标和 Cs 离子抑制剂有助于测定高浓度的 Na 和 K 等元素。覆盖宽的测定范围的另一个途径是使用双向观测 (DV) ICO-OES 仪器，用水平观测测定痕量元素，用垂直观测测定营养元素。但是，为了分析所有元素，传统的 DV 仪器需对样品进行多次序列分析。在本文中，我们使用拥有独特智能光谱组合 (DSC) 技术的 Agilent 5100 同步垂直双向观测 (SVDV) ICP-OES，一次读数同时完成水平和垂直光路测定，确保垂直光路测定 Na 和 K 等常量元素，同时水平光路测定痕量元素。这样一来扩展了测定的上限，降低了 Na 和 K 等营养元素的分析干扰，同时还可测定 Zn、Cu 和 Mn 等痕量元素，无需耗费额外时间，更可降低每个样品分析的氩气消耗量，获得准确而精密的数据以及无与伦比的线性动态范围 (LDR)。

The 5100 Synchronous Vertical Dual View (SVDV) ICP-OES has a range of features that simplify the analysis and sample preparation procedures required for the Chinese National Food Safety Standard (GB 5413.21—201) for measuring Ca, Fe, Zn, Na, K, Mg, Mn and Cu in milk powder for infants.

过去一直使用火焰原子吸收系统 (FAAS) 或配备垂直炬管的径向 ICP-OES 分析地质样品。但是这些技术却难以实现低成本、高通量地分析地化样品。地化样品中元素众多且浓度不一，需要多次稀释，尤其是使用 FAAS 时更是如此。此外，样品中还含有高浓度的总溶解固体 (TDS)，从而导致需要 频繁清洗样品引入系统。本应用简报使用 Agilent 5100 同步垂直双向观测 (SVDV) ICP-OES 来分析含有最高 2.5% TDS 的地化样品。本文展示了该仪器的准确度和灵活性，还测定了样品测量速率和每个样品的氩气消耗量。

电感耦合等离子体光学发射光谱 (ICP-OES) 以其多元素分析能力、宽线性动态范围和操作简便而成为一种测定 REE 不错的替代方法。此外，在一些情况中，应用其他仪器方法时，获取样品特征检验其他目标分析物的潜在干扰元素至关重要。例如，相比于 ICP-MS 测定双电荷物质（如 150Sm2+ 和 150Nd2+）产生 75As+ 的干扰数量级，ICP-OES 能够更灵活地选择无干扰的发射波长和观测位置。本研究采用 Agilent 5100 同步垂直双向观测 (SVDV) ICP-OES（5110 SVDV ICP-OES 也适用于本应用）测定地质样品中的 REE（Dy、Er、Eu、Gd、Ho、La、Lu、Nd、Pr、Sc、Sm、Tb、Th 和 Tm）。在 SVDV 观测模式下，通过一次读数获取轴向和径向等离子体观测数据，5100 和 5110 仪器能够实现同步测量。同步垂直双向观测 (SVDV) 模式能够节省数据采集时间，从而减少每个样品的氩气消耗量。

Traditionally, geological samples are analyzed using flame atomic absorption (FAAS) and/or radial ICP-OES with a vertical torch. Achieving high sample throughput at a low cost per analysis for geochemical samples can be challenging when using these techniques. The samples often have a wide range of element concentrations, requiring multiple dilutions, particularly when using FAAS. The samples also have high levels of total dissolved solids (TDS), which requires frequent cleaning of the sample introduction system. In this application note, the Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES was used to analyze geochemical samples containing up to 2.5% TDS. As well as demonstrating the accuracy and flexibility of the instrument, the sample measurement rate and argon consumption per sample were determined.
