The Use of Kits in the Analysis of Tissue Lipids Requires Validation

The ready availability and ease of use of kits for the measurement of serum lipids has greatly facilitated these measurements. In many cases it would be convenient to use these kits in the determination of lipid concentrations in tissues. The successful application of serum kits in tissue analysis requires that two important issues be considered. First, the solvent system for the extraction of the lipids and the solvent used for analysis by the kit must be compatible with the reactions in the kit. Second, the concentration range in the analyzed solution must be within the range for which the kit is used. We report here that lipids in liver and adipose tissues may be significantly underestimated by the use of some kits. We recommend that the use of kits for tissue analysis of lipids be validated for the specific analysis.

Qualification of Image-Based Measurement Systems for Characterization of Sprays

Image-based measurement techniques become increasingly popular and expedite digitalization in chemical engineering. This article demonstrates their potential by testing two inline probes, namely modified optical multimode online probe (OMOP) and process microscope. Validations are performed with static monodisperse standards (9.2 µm to 406 µm) and fast-moving droplets (68.6 µm to 860.7 µm; 24.5 m s⁻¹ to 11 m s⁻¹). Screening of a lithography attests both probes great distortion-free image quality. A 1951 USAF chart attests a low optical resolution of 8 µm or 7 µm with respect to the OMOP or process microscope, respectively. The modified OMOP and process microscope reaches accuracies of 7.6 % or 5.9 % for particles and 8.2 % or 6.8 % for droplets.

Catalyst Characterisation and Preparation Using Sample Controlled Thermal Techniques—High Resolution Studies and the Determination of the Energetics of Surface and Bulk Processes

This paper summarises some applications of advanced thermal techniques for the characterisation and preparation of catalysts using different sample controlled thermal analysis (SCTA) methods. The techniques are applied to temperature programmed decomposition (calcination), oxidation, reduction, dehydration, desorption and reaction. SCTA methods can produce significant enhancements in the resolution of complex reactions, provide a detailed insight into the energetics of surface and bulk processes and, when applied to catalyst preparation, give improvements in the pore structure and uniformity of the resulting materials. The advantages and limitations of SCTA methods, in which the sample temperature or concentration of reactant gas is altered as some function of the rate of a thermally induced physico-chemical process, are discussed.

Physico-chemical characterisation of Indian biomass ashes

India stands fourth in biomass utilisation for various purposes like domestic, commercial and industrial applications. While extensive studies have been made for coal ash characterisation and utilisation, studies on characterisation of biomass ash and its utilisation has not been addressed. In this paper, biomass ash from five sources i.e. rice husk, bagasse, groundnut shell, cashewnut shell, and arecanut shell have been characterised. Chemical composition analysis, particle size analysis, thermal analysis, and microstructure analysis were carried out. Results show that in all ashes silica is the major compound with particle size ranging from 15 to 30 μm and having irregular shape. Ash powders originating from cashewnut shell, arecanut shell and groundnut shell also have compounds of calcium, magnesium and potassium. Bagasse and cashewnut shell ashes have high LOI due to presence of unburnt carbon, P₂O₅ and other volatiles.
