Latest Application Notes
Determination of Methanol Content in Biodiesel using Gas Chromatography with Headspace Sampling According to EN-14110
The popularity and interest in biodiesel is significantly growing in many areas of the world and has become a commonly sought after alternative fuel source for use with diesel engines.
Multi-residue Analysis of PAHs, PCBs and OCPs on an Agilent J&W FactorFour VF-5ms GC Column
During multi-residue analyses, different groups of compounds are analyzed in a single run. Reducing time is one of the most important advantages of this approach. For environmental samples, different analyses usually have to be performed for each type of sample.
Quantitation Limit of Pharmaceuticals by UV Spectrophotometry
Quality control and securing product safety are important in the manufacture of pharmaceutical products, so it is essential that substances other than those specifically approved are not included with the specified ingredients. This means that contaminants from the environment must not become mixed in with the product ingredients and residual substances adhering to the manufacturing equipment must not contaminate the next product to be processed by that equipment.
Absolute Reflectance of Anti-Reflective Film for Solar Cells
Solar cells, devices which convert light energy to electrical energy, are presently undergoing active research. Various innovations are being implemented to raise the conversion efficiency, and one of these is anti-reflective film which is used to increase the amount of sunlight reaching the cell.
Quantitation of Nucleic Acid
The BioSpec-nano has 2 optical pathlengths (0.2 mm, 0.7 mm), allowing quantitation of nucleic acid with sample volumes of 1 µL and 2 µL, respectively. In addition, if the optional cell (sample volume: 2 mL) having a 5 mm pathlength is used, measurement can be conducted using the cell (cuvette).
Analysis of Contaminants in Foods
Concern for food is rising these days due to events of contamination with toxins and deceptive labeling of origin, etc., and one concern related to food safety is contamination with foreign substances.
Analysis of Black Rubber Diaphragm by FTIR and EDX
This Application News article introduces the qualitative analysis of a rubber diaphragm sample using both FTIR and EDX techniques.
Measurement of Minerals in Dietary Supplements by Atomic Absorption
Recently, the development and sales of a variety of dietary supplements have increased dramatically against the background of rising public interest regarding health. This application note introduces the method of analysis of minerals in dietary supplements as specified in the Pharmacopoeia of the United States, where the supplement market now stands at about three trillion yen (33 billion dollars).
Aroma research, flavour science, production process control
Proton Transfer Reaction-Mass Spectometry (PTR-MS) with its online measurement capabilities enables researchers to quantify compounds in the nose space air of test persons.
Monitoring of volatile organic contamination in cleanroom environments
Airborne molecular contamination (AMC) is a concern for any high technology manufacturing process, especially in the microelectronics industry. Organic contamination may cause adverse effects on production tools and consequently increase costs for high-tech companies.
