“…The Armitage group has pioneered the use of DART-MS for analysis of natural dyes for applications to ancient textiles [9,[19][20][21][22] and other cultural heritage materials [23][24][25]. While paper spray has been used by others for characterizing both natural and artificial colorants in food and beverage [26,27], this is the first instance of which we are aware for its use in heritage science applications. We present here the results of using DART-MS and paper spray MS for identifying the colorants in a selection of the Peruvian dye samples from the Saltzman Collection, along with HPLC-DAD and HPLC-ESI-Q-ToF analyses for comparison and validation of the results.…”

Yarn samples from the Saltzman Collection of Peruvian dyes were characterized by several different analytical techniques: high performance liquid chromatography with both diode array detection (HPLC-DAD) and electrospray ionisation with tandem mass spectrometry (HPLC-ESI-Q-ToF), direct analysis in real time (DART) mass spectrometry and paper spray mass spectrometry. This report serves primarily as a database of chemical information about the colorants in these dye materials for those studying ancient South American textiles and their colorants. We also provide a comparison of the results obtained by currently widespread HPLC techniques with those of two different ambient ionisation direct mass spectrometry methods to highlight the advantages and disadvantages of these approaches.

Detection of Analgesics and Sedation Drugs in Whiskey Using Electrochemical Paper‐based Analytical Devices

The adulteration of whiskey with analgesics and sedation drugs has been a common practice to prevent hangover the following day and promote loss of consciousness. In both situations, the portable and low cost detection platforms are of paramount importance for forensic investigations. This report describes the use of electrochemical paper‐based analytical devices (ePADs) fabricated by pencil drawing for detecting metamizole, paracetamol and midazolam maleate in whiskey. Different types of paper substrates and graphite pencils were initially characterized with ferrocyanide. The best results were achieved using vegetal paper and Aquarelle/6B pencils. ePADs revealed a decrease in current signal indicating a short lifetime, thus limiting their use to disposable sensors. Despite the short lifetime, the graphite pencil ePADs revealed good electrochemical reproducibility (RSD=3.3 %). The forensic feasibility of the proposed ePADs was demonstrated through the analysis of metamizole and paracetamol in whiskey. The limit of detection (LOD) achieved for paracetamol and metamizole were 45 and 20 mg L−1, respectively. ePADs were also tested to detect midazolam maleate in whiskey. The signal recorded exhibited linear correlation in a wide concentration range (25–1000 mg L−1) and a LOD of ca. 5 mg L−1. Considering the disposability and operational simplicity, ePADs offer a good strategy for detecting adulterations in alcoholic beverages at the point‐of‐need.

“…Samples were quantified using PS MS, and the extent of mixing was determined by using various chemometric methods such as principal component analysis and partial least squares (Li et al, ; Mazzotti et al, ; Pereira et al, ; Tosato et al, ; Yu et al, ). Perfumes have been analyzed in a similar manner to adulterants in alcohol (Guo et al, ). Foodstuffs such as olive oil have been characterized using PS MS with enhanced ionization efficiency by doping the sample with silver nitrate (Lara‐Ortega et al, ).…”

Mass Spectrometry Reviews

Recent advancements in the sensitivity of chemical instrumentation have led to increased interest in the use of microsamples for translational and biomedical research. Paper substrates are by far the most widely used media for biofluid collection, and mass spectrometry is the preferred method of analysis of the resultant dried blood spot (DBS) samples. Although there have been a variety of review papers published on DBS, there has been no attempt to unify the century old DBS methodology with modern applications utilizing modified paper and paper‐based microfluidics for sampling, storage, processing, and analysis. This critical review will discuss how mass spectrometry has expanded the utility of paper substrates from sample collection and storage, to direct complex mixture analysis to on‐surface reaction monitoring.
