石腦油中微量雜質的 ICP 分析檢測

石腦油通常作為汽輪機的燃料。如果石腦油中的雜質元素含量過高,將會縮短汽輪機的使用壽命。本文采用水平觀測ICP 建立了對石腦油中微量雜質的分析方法。

湖南沅水流域戰國時期楚墓出土古代玻璃器的成分分析

采用激光剝蝕電感耦合等離子體發射光譜技術分析了湖南沅水流域楚墓出土的11件玻璃璧和2件蜻蜓眼珠的化學成分,并對化學成分進行了多元統計分析。結果表明:這些玻璃器都屬于鉛鋇硅系玻璃,是戰國時期重要的一種國產玻璃。玻璃璧的來源單一,而蜻蜓眼則為不同來源。與其它已經發表的鉛鋇玻璃璧的數據進行比較,顯示湖南南部在戰國時期可能是當時主要的鉛鋇玻璃璧生產中心。同時探討了不同顏色玻璃的呈色機理。結果表明,古代楚國工匠可能通過調整玻璃中鉛鋇硅含量的比例來控制玻璃的酸堿度,從而得到預期的玻璃顏色。

等離子體發射光譜測定煤灰中雜質含量

飛灰中含有大量的金屬雜質,是大氣污染的主要來源,因此對飛灰的檢測對環境保護就顯得格外重要。本文采用ICP-OES(Prodigy Leeman Labs)對飛灰中金屬雜質進行了系統分析,分析結果與NIST SRM 1633b 標準樣品比較,結果優良。

ICP 指紋技術應用

全譜ICP固體檢測器主要的特征是具備一次測定未知樣品中所有元素,也即元素“指紋”譜圖。此技術在QC及仲裁方面具有強大的功能。為實現“指紋”功能,要求ICP全波長覆蓋及對應的全譜數據處理功能。本文將描述Prodigy ICP有關元素“指紋”技術的性能。

Western technical traditions of pottery making in Tang Dynasty China

This study is based on the SEM-EDS and LA-ICP-AES analyses of a sample of twenty-nine Tang sancai sherds unearthed from the Liquanfang site, Xi’an city. The results indicate that ceramics with yellowish bodies are calcareous and those with red bodies were made of ferruginous clays.

Determination of Trace Elements in Copper by Radially Viewed ICP

Copper is considered to be the first metal used by man and has been mined for more than 10,000 years. Since copper is a soft, malleable metal, early civilizations learned to fashion tools, containers, ornaments and weapons from it. Once it was discovered that the addition of a small amount of tin to molten copper produced an alloy that was harder than copper, the Bronze Age had begun.

Determination of the Halogen Elements in the Deep UV Region of the Spectrum by ICP

There are many applications where the ability to measure the halogen elements, at the same time as the metallic elements, is desirable. A few of these include the measurements of Cl and Br in refinery process fluids, the measurement of Cl and Br in waste oils and the determination of Cl-, Br- and I- in food supplements and drinking water.

Determination of Alloying Elements in High Carbon Steel by Radially Viewed ICP

Carbon steels are by far the most frequently used steels. More than 85% of the steel produced in the US is carbon steel. These steels are classified by their carbon content. Table 1 shows the classification of carbon steels and some typical uses.

Chemical and lead isotope analysis from the Warring States Period

In the context of the present study, we have conducted chemical and lead isotope analyses on twelve ancient glass samples unearthed from Chu tombs in Changde City, Hunan Province. The results of the chemical analysis of these samples show that all samples are PbOeBaOeSiO2 glasses, thus indicating that they are all traditional ancient Chinese glasses. The chemical results also suggest that all Bi wares may either share a common source or were produced according to similar recipes. In turn, the eye beads are different from the Bi wares for their distinct chemical composition.

Chemical analysis of white porcelains from the Ding Kiln site, Hebei Province, China

The Ding kilns were some of the most famous early kilns of medieval China, producing huge quantities of white and cream-white porcelains of outstanding technical and aesthetic quality. Since 1949 they have been excavated three times, in 1965, in 1987, and in 2009 respectively. In this latest study 69 white porcelain sherds from assured contexts and from the 2009 excavations were analyzed using laser ablation techniques (ICP-AES).
