Laser Ablation APCI-HRMS Method for the Analysis of Cultural Heritage Materials.

ABSTRACT: Analyzing cultural heritage (CH) materials, particularly organic substances, is challenging due to their complex chemical composition. A key requirement in such analyses is the use of analytical techniques that cause minimal damage to the artifact while providing the maximum amount of chemical information about the materials. Chromatographic and mass spectrometric (MS) techniques give valuable information about components of the organic materials, but these typically require a microsample from the object, along with specific preparation and instrumental conditions. For CH artifacts, techniques that work directly on the surface, thereby causing minimal damage, are far more desirable. We have developed a 355 nm optical fiber-coupled laser ablation (LA) atmospheric pressure chemical ionizatio
