    The Power of the Sun, Solar Energy Development Solutions

    幸运8平台彩票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.

    Safeguarding the Authenticity of Herbs & Spices

    Infrared (IR) and near-infrared (NIR) spectroscopy are fast, easy-to-use techniques with a history of being used for food applications such as those for measuring protein, moisture, and fat content. Food fraud and adulteration has become of particular concern to the industry over the past few years following reports of incidents in the media, with herbs and spices identified as one of the key problem areas.

    Weighing the Benefits and Risks of Nanotechnology White Paper

    幸运8平台彩票There is a growing body of evidence showing that there are significant differences between some nanomaterials and their non-nanoscale counterparts. What those differences portend raises many new questions about their potential to cause harm to human health and the environment.

    Determination of Oil Content in Membranes Used in Compressed Air Sampling by Infrared Spectroscopy

    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.

    Accurate Sizing and Precise Counting of 10 nm Gold Nanoparticles using the NexION 2000 ICP-MS

    In this work, we demonstrate that PerkinElmer's NexION® 2000 ICP-MS, with its unique RF generator and ion optics, coupled with the Syngistix™ Nano Application Software Module, can be used to accurately measure and characterize NP sizes of 10 nm and smaller, both alone and in a mixture of NPs of various sizes.

    Measurement of Gold Nanoparticle Solutions on the LAMBDA 265

    The data shows the suitability of the LAMBDA 265 for producing rapid, high-quality spectra. It also shows that the instrument is able to measure the higher nanoparticle sizes, even though these scatter light to a greater extent due to the increased particle size and also settle out more quickly.

    Water Analysis Using LAMBDA UV/Visible Spectrophotometers: Iron Determination

    Iron is rarely found in its elemental form in nature due to the high tendency of its ions, Fe(II) and Fe(III), to form oxygen and sulphur containing compounds. Concentrations of iron found in surface waters are typically no greater than 1 mg/L, unless contaminated by industrial effluents, whilst much higher concentrations are found in ground waters. The World Health Organization guideline for iron in drinking water is 0.3 mg/L as undesirable bacteria growth in water systems occurs above this concentration. In this application, the quantitative analysis of iron was performed using the LAMBDA 265™ UV/Vis spectrophotometer and CHEMetrics iron cell test kit.

    Discrimination of Herbal Lifestyle Products Using AssureID SIMCA and COMPARE Algorithms

    Herbal lifestyle products are widely used as alternatives to medicines around the world, with as many as 80% of people using them as a primary source of healthcare in developing countries. These treatments are commonly regarded by scientific papers, and on some occasions the media, as being inferior to orthodox treatment. This is due to the variation between herbal formulations which will not be present in so called ‘single-chemical’ drugs. The reasons for the aforementioned variation involve several factors including storage, environmental conditions, handling and unintentional or intentional contamination (adulteration).

    The Analysis of Precious Metals in Mining with the PinAAcle 500

    When mining for precious metals, ores are extracted from the ground and subjected to various sample preparation procedures in order to remove the metals of interest. A commonly used procedure to isolate metals from the ore is fire-assay, which leaves a matrix-free “button” of the metal. This work will focus on the analysis of precious metals in simulated digested precious metal buttons, with an added emphasis on assessing the lowest limits which can be accurately measured.

    Biodiesel Concentration Measurements Using Attenuated Total Reflectance (ATR)

    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.

    Simple Method of Measuring the Band Gap Energy Value of TiO2 in the Powder Form using a UV/Vis/NIR Spectrophotometer

    The measurement of the band gap of materials is important in the semiconductor, nanomaterial and solar industries. This note demonstrates how the band gap of a material can be determined from its UV absorption spectrum.

    Augmenting Standard Methods of Measuring Airborne PM2.5 Using IR Imaging

    幸运8平台彩票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
