Nicolas Poussin（Les Andelys，1594–Rome，1665）于1626年左右创作的两幅婴儿玩具（Museo Nazionale d'Arte Antica，巴贝里尼宫，意大利罗马）在1626年左右被绘制为“ guazzo”，这意味着用胶水或鸡蛋结合介质。迄今为止，尚未通过分析确认这一点。使用铋团簇液态金属离子枪和氩气团簇离子束的双束飞行时间二次离子质谱仪（TOF-SIMS）可以将有机物和无机物映射到绘画的横截面上，并且有可能以获取样品的亚微米分辨率质谱图像，以及使用二次离子的延迟萃取获得的高质量分辨率。预先通过抛光或切片机切割来制备两幅画的横截面表面，然后直接在仪器真空室内使用气体簇离子束进行清洁。通过TOF-SIMS分析研究了两幅画中粘合剂的性质。通过考虑异质分析表面的不均匀物理特性，使用不同的仪器设置记录了几张高分辨率图像。脂质的检测似乎指向含油介质，而不是胶结合介质。由油和胶制成的乳液是另一种假设，可以用来更好地了解艺术家在其早期职业中的工作方法。通过TOF-SIMS分析研究了两幅画中粘合剂的性质。通过考虑异质分析表面的不均匀物理特性，使用不同的仪器设置记录了几张高分辨率图像。脂质的检测似乎指向含油介质，而不是胶结合介质。由油和胶制成的乳液是另一种假设，可以用来更好地了解艺术家在其早期职业中的工作方法。通过TOF-SIMS分析研究了两幅画中粘合剂的性质。通过考虑异质分析表面的不均匀物理特性，使用不同的仪器设置记录了几张高分辨率图像。脂质的检测似乎指向含油介质，而不是胶结合介质。由油和胶制成的乳液是另一种假设，可以用来更好地了解艺术家在其早期职业中的工作方法。

Time-of-Flight Secondary Ion Mass Spectrometry Imaging of Cross Sections from the Bacchanals Paintings of Nicolas Poussin

The two paintings Infant Bacchanals (Museo Nazionale d’Arte Antica, Palazzo Barberini, Rome, Italy) executed by Nicolas Poussin (Les Andelys, 1594–Rome, 1665) in around 1626 are thought to have been painted “a guazzo”, which means either with a glue or with an egg binding medium. To date, this has never been confirmed through analysis. Dual-beam time-of-flight secondary ion mass spectrometry (TOF-SIMS), using a bismuth cluster liquid metal ion gun and an argon gas cluster ion beam, allows the mapping of organic and inorganic matter on paintings cross sections, with the possibility to acquire submicrometer-resolution mass spectrometry images of the sample, together with high mass resolution using a delayed extraction of secondary ions. The surfaces of cross sections from both paintings were prepared beforehand either by polishing or by microtome cutting and then cleaned with the gas cluster ion beam directly inside the vacuum chamber of the instrument. The nature of the binders in the two paintings was investigated by TOF-SIMS analyses. By considering the uneven physical properties of the heterogeneous analyzed surfaces, several high-resolution images were recorded with different instrument settings. The detection of lipids seems to point toward an oil-containing medium, rather than a glue-binding medium. An emulsion made of oil and glue is another hypothesis to be explored to better understand the artist’s working methods in his early career.
