As the demand for solar power continues to grow, there needs to be a clear focus on different key issues in the life cycle of a solar cell. These issues are: efficiency, durability and cost. Coupling PerkinElmer’s application knowledge and experience together with our product portfolio, we can help manufacturers overcome these obstacles. At PerkinElmer, we’re taking action to ensure the quality of our environment.
Designed specifically to meet the requirements of the Caterpillar® S.O.SSM program, the JOAP program, and the new ASTM® Methods D7412, D7414, D7415, D7418, Spectrum™ OilExpress is the fastest, most cost-effective Oil Condition Monitoring (OCM) solution for busy test laboratories. OilExpress also uses less than half the solvent required by competing systems, dramatically reducing day-to-day operating costs and making laboratories more competitive.
This note describes the test method for the quantitative analysis of aerosol oil and liquid oil typically present in the air discharged from compressors and compressed air systems. The method is rapid, sensitive and cost effective and shows the FT-IR can be an effective tool for the monitoring of oil content. The methodology followed for the analysis by FT-IR is reported in Bureau of Indian Standard and we have also tested for its ruggedness, spike recovery, linearity and detection limits.
This study shows that DSC can be used to study the curing degree of the EVA resin by measuring the residual curing enthalpy. The data show that the residual curing enthalpy can be correlated to the curing time in a linear way. The DSC test is quick and easy.
Biodiesel fuels are often blended compositions of diesel fuel and esterified soybean oils, rapeseed oils, or other potential vegetable oils as well as fats. The physical and combustion properties of these biofuels have allowed them to achieve similar performance to diesel fuel. However, there are several characteristics that are of concern. These differences, especially the cetane reduction, require that adequate control of the biofuel concentration be implemented.
The use of IR imaging expands the measurement possibilities by giving information about the individual types of materials present in the collected particles. The information from the IR imaging experiment is not only qualitative (i.e. identification of the particulates), but can also be calibrated to give quantitative information on the components present. The IR imaging measurement will take only five minutes, whereas Ion Chromatography requires solvent extraction of the particulates and would take around 20-25 minutes per sample
幸运8平台彩票A gas chromatographic analysis of the extract can provide even greater sensitivity and more detailed compositional information, but further increases the time required for the analysis. Thermogravimetric analysis coupled to infrared spectroscopy (TG-IR) can provide detailed information about the amount and nature of the pollution, while requiring no sample preparation at all. This application note illustrates the kind of data that can be obtained with a modern TG-IR system.
幸运8平台彩票Where ΔCp and ΔCp pure are the changes in specific heat at the glass transition temperature, Tg, for the composite, and for the unfilled polymer, respectively. This work suggests an alternative method for determining Cp that takes advantage of fast heating and cooling rates to obtain quantitative Cp in the upper temperature region without having to dwell in that high temperature region to establish an upper isothermal.
幸运8平台彩票Infrared spectroscopy is particularly suitable for the identification of materials, even when the differences between the materials are subtle variations in complex mixtures. In this note we demonstrate that biodiesel from several common feedstocks can be distinguished on the basis of absorption bands arising from double bonds in the fatty acid chains.
幸运8平台彩票IR spectroscopy is an ideal method for quantifying benzene at the concentration levels required, and there are several standard methods for this measurement, all of which utilize the distinctive C–H out-of-plane deformation band at around 673 cm-1. While this band is characteristic of benzene, toluene and xylenes have some weak absorption at this frequency that can interfere with the results if high concentrations are present.
幸运8平台彩票The purpose of this study is to demonstrate the proximate analysis of two standard samples using the STA and show that the performance is easily able to allow this moderate cost, small profile and sturdy instrument to be used for this type of routine analysis.
In the “Early Drug Discovery Phase” of pharmaceutical development when there is a minimum amount of synthesized drug candidate, quick thermal analysis using a small amount of sample is the norm. The sample amount could be less than 3 mg. Because of the rush to identify possible drug candidates, analytical answers must be given within the day. The STA 6000 with its sensitivity of 0.1 µg allows minimum sample material to obtain reproducible results in half the time.
