Time-of-flight secondary ion mass spectrometry (TOF-SIMS) imaging using cluster primary ion beams is used for the identification of a green painting layer on the scene The Angels Concert from the Issenheim Altarpiece (painted in 1516) from a German Renaissance painter, Matthias Grünewald. Copper carboxylate clusters inside a basic copper chloride (atacamite) layer have been identified and located in the copper green layer. The mechanisms of transformation of atacamite into copper carboxylates may be initiated by an aging of the paint layers. The combination of the high mass resolution of the technique together with a micrometer spatial resolution and the possibility to simultaneously identify both minerals and organics, has proven to be the method of choice for the study of the stratigraphy of a paint cross-section.
利用团簇初级离子束的飞行时间二次离子质谱（TOF-SIMS）成像技术，对德国文艺复兴画家马蒂亚斯·格吕内瓦尔德（Matthias Grünewald）于 1516 年创作的《伊森海姆祭坛画》（The Angels Concert）场景上的一个绿色绘画层进行了鉴定。在一个基本的氯化铜（氯铜矿）层内鉴定并定位了铜羧酸盐簇，该层内有铜羧酸盐簇。氯铜矿向铜羧酸盐转化的机制可能是由颜料层老化引发的。该技术具有高质量分辨率，同时具有微米级空间分辨率，并能同时鉴定无机物和有机物，这一特性已被证明是研究绘画剖面层的首选方法。
