Book Synopsis Surface Layer Matrix-assisted Laser Desorption Ionization Time of Flight Mass Spectrometry (SL-MALDI-ToF MS) Analysis of Polymer Blend Surface Composition by : Jacob A. Hill
Download or read book Surface Layer Matrix-assisted Laser Desorption Ionization Time of Flight Mass Spectrometry (SL-MALDI-ToF MS) Analysis of Polymer Blend Surface Composition written by Jacob A. Hill and published by . This book was released on 2017 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The composition of a polymer blend is generally different at the surface than in the bulk and the gradient in composition with depth has important implications for surface properties. The determination of the surface composition presents various challenges which continue to prompt the development of new techniques for quantifying the composition. Here the technique of surface layer matrix-assisted laser desorption ionization time-of-flight mass spectrometry (SL-MALDI-ToF-MS) has been further developed to address four specific questions of polymer blend surface behavior within the general category of surface composition determination.The first question is how chain length disparity affects surface segregation in the case that the disparity is quite small. While such segregation is known for blends containing low molecular weight additives or systems with large polydispersity, it has not been reported for anionically polymerized polymers that are viewed, in practice, as monodisperse. For 6 kDa polystyrene the number average molecular weight (Mn) at the surface is ca. 300 Da (5%) lower than that in the bulk and for 7 kDa polymethyl methacrylate the shift is ca. 500 Da.The second question is how chain-end functionalization effects not the location of chain ends at the surface, but rather the prevalence at the surface of any part of a chain having an end functionalization. A key issue of such an approach is understanding precisely where the functionalities ultimately reside and how this functionalization shifts the balance of forces that determine the distribution of chains with depth. The surface of a blend of 6 kDa polystyrene and 6 kDa polystyrene functionalized with hydroxymethyl ends is not only depleted of the higher energy end groups, but is depleted of any segments belonging to the functionalized chains. This is demonstrated using SL-MALDI-ToF-MS, which detects entire chains that have any repeat unit at the outer surface, and requires no labelling. This study was extended to the surfaces of blends of 6 kDa polystyrene and 6 kDa polystyrene functionalized with hydroxyethyl ends. Blends of all compositions less than 90 wt. % functionalized chains showed depletion.Finally, the challenge of determining lateral variations in the surface composition has been addressed with the development of SL-MALDI-ToF-MS imaging (SL-MALDI-ToF-MSI). Key to developing imaging capability was improving the lateral uniformity of the matrix deposition. This uniformity was achieved using solvent free sublimation of matrix and salt onto the sample's surface. The capabilities of SL-MALDI-ToF-MSI were demonstrated by imaging the absence of material due to masking during material deposition, mechanical scribing or solvent perturbation at the surface of low molecular weight poly(methyl methacrylate) and polystyrene thin films. SL-MALDI-ToF MSI was made possible through the first uniform, solvent free simultaneous sublimation of matrix and salt onto the material's surface.

Book Synopsis Nonpolar Matrices for Matrix Assisted Laser Desportion Ionization - Time of Flight - Mass Spectrometry by :
Download or read book Nonpolar Matrices for Matrix Assisted Laser Desportion Ionization - Time of Flight - Mass Spectrometry written by and published by . This book was released on 2005 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has been used extensively for the characterization of large biomolecules, synthetic polymers and small molecules. Typically, low molecular weight acidic matrices have been used in MALDI-MS for such analyses. Here, the use of low molecular weight nonpolar matrices for MALDI-MS is investigated. In particular, the analytical and physical properties of this class of matrices are studied. The effect of instrumental factors on nonpolar matrix behavior was investigated. Two different MALDI target substrates, stainless steel and poly(methylmethacrylate) (PMMA), were used. The radical molecular ion abundance of nonpolar analyte ions analyzed in the presence of various nonpolar matrices, such as anthracene and 9-cyanoanthracene, were determined as a function of the MALDI target substrate. It was found that PMMA MALDI target substrates yielded higher radical molecular ion abundances for nonpolar analyte ions than stainless steel MALDI target substrates. This difference is attributed to the absence of photoelectrons which reduce charged species in the plume. To determine whether the desorption process for nonpolar matrices is different than the desorption process for polar, acidic matrices, matrix initial ion velocities were measured in MALDI-MS. The relative initial ion velocities of the nonpolar matrices, anthracene, 9-cyanoanthracene, pyrene, and acenapthene and were investigated and compared to the relative initial ion velocities for 2,5-dihydroxybenzoic acid (DHB), sinapinic acid (SA), and all-trans retinoic acid (RTA), polar matrices. It was found that DHB has a greater relative initial ion velocity than the nonpolar matrices. It does not appear that the desorption process is different between nonpolar and polar matrices based upon these results. In addition, when using any matrix, polar or nonpolar, to analyze nonpolar polymers, the addition of a metal salt increased the relative initial ion velocity of the matrix, suggesting a different desorption mechanism in these cases. To illustrate an application of nonpolar matrices for analytical MALDI-MS, an atmospheric resid crude oil fraction was characterized. The MALDI mass spectral data for this sample was difficult to interpret when a polar matrix, 3-indole acrylic acid, was used, due to fragmentation and matrix clustering in the analyte molecular weight distribution range. The nonpolar matrices anthracene and 9-cyanoanthracene were found to be very suitable for the analysis of this sample in either linear or reflectron mode time-of-flight mass spectrometry. These matrices did not lead to fragmentation or clustering, and identification and characterization of the analyte peaks were straightforward.
