Book excerpt: The U.S. Bureau of Mimes is investigating Fourier transform infrared (FTIR) spectroscopy for on- filter quartz analysis of respirable dust. A custom accessory is described for full-face examination of filters utilizing a large-diameter infrared (IR) beam. The accessory positions samples to match diameters with that of the diverging analytical beam. Sample absorbance is then measured. With nonuniform deposition of dust on collection filters being a major issue for such analyses, this approach is the most direct way to accomplish sample area averaging. The approach is unconventional since it utilizes large-beam geometries instead of the usually desired minimized beam dimensions. The issues and problems involved in the analysis of quartz on a filter matrix are discussed. Absorption bands chosen, light-scattering effects, curved baselines, random noise, interference fringes, and possible solutions to technical difficulties are the topics covered. The more significant findings include a 20-pg detection limit for quartz when the custom accessory is used and minimal occurrence of light-scattering effects at low wavenumbers. The custom accessory performance was satisfactory and merits further work. With continued research, an on-filter method for quartz analysis of respirable dusts seems achievable

Available in PDF, EPUB and Kindle. Book excerpt: Characterization of Polymers and Fibres addresses an integral part of fiber and polymer manufacturing processes that is crucial in helping manufacturers ensure that final products achieve intended specifications. The characterization of fiber and polymers is needed for attributes including molecular weight, morphology, dyeing behavior, tensile, optical and thermal behavior. This book covers a wide range of characterization techniques, including thermal, X-ray diffraction, solubility, tensile, optical, hygroscopic and particle size distribution. Introductions and definitions are provided where beneficial to make topics accessible to a broad range of readers in both academia and industry. Addressing advances from the fields of bioscience, polymer science, material science, and textile science, this book is wide in scope, drawing on the latest research to provide details of characterization techniques and equipment. Provides a thorough description of the material quality control process, including the latest industry practice Presents material characterization at all levels, from the atomic level to surface structure Covers technical advice on natural fiber characterization methods, including XRD, XPS, TGA, SEM, TEM, AFM, Contact angle, Particle size analysis, FTIR, and NMR

This book was released on 2014 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: India is endowed with huge reserves of various minerals (as many as 89) and, therefore, the mining sector is very large employing millions of workers who are regularly exposed, in various degrees, to quartz dust in workplaces. Although the mining sector is quite old and well established, the reported data related to dust and its quartz content are few and far between. The work presented herein is a study of the quartz content in respirable airborne dust generated in coal and metal (zinc and manganese) mines,with a view to evaluating the health risk of miners as per mines regulations. The direct-on-filter method using an Fourier transform infrared (FTIR) spectrometer has been adopted for the determination of quartz. Personal air samplers were used to collect dust from different locations in mines on GLA-5000 PVC membrane filters. The air samplers were either attached with different workers engaged in a shift or placed in a position near to the dust-generation source in the mines to collect dust for direct-on-filter analysis. The proportion of quartz in the dust was determined from an estimation of the intensity of the doublet at 800 cm-1 calibrated against that of on-filter standard quartz dust. It has been found that the percentage of quartz in the dust in coal mines, especially in coking coal mines situated in the Jharia coalfield, is less than 1 % in almost all the workings, barring a few cases where it has exceeded this value. In contrast, the proportion of quartz in dust in metal mines exceeds 5 % in many workings. It has been found that wet drilling and good ventilation systems help to control dust problems at some locations, whereas rotation of workers may be needed in some places where it is difficult to suppress dust to a safe level.
