European Patent for the Use of Nanoparticles in the Preparation of Calibration Standards
This European Patent concerns the use of nanoparticles comprising an analyte in the prepartion of a calibration standard for use in an analytical atomic spectroscopic technique and a method of calibrating such an instrument. The application for this European Patent...
Fatty Acid Methyl Ester & Fatty Acid Ethyl Ester Standards (FAME and FAEE Standards)
Free fatty acids (also referred to as volatile fatty acids or carboxylic acids) can be difficult to analyse for two reasons. The first, is because of their high polarity, which leads to adsorption problems in columns. The second, is that in the case of unsaturated fatty acids, these may only show small peak differences, which are difficult to distinguish. So, esterification of fatty acids is an important tool for both characterising fats and oils and for quantifying the total fat content of several materials in particular fat content of foods and foodstuffs. It is also an important technique for assessing the quality and purity of biofuels and on an industrial scale, the production of biofuels. Reagecon offers an extensive range of FAME and FAEE Standards.
Five Benefits of Using Reagecon Conductivity Standards
Reagecon is the worlds largest producer of conductivity standards and offers over 45 different values of such standards. The company is the only producer in the world with the capability to manufacture and stabilise these products at such low levels of conductivity....
How Do I Measure pH Accurately and Consistently?
John Barron, Technical Director of Reagecon, offers his top 10 tips on how to measure pH accurately and consistently. 1. Selection of the pH Measurement System The selection of an appropriate measurement system that includes metre, electrode, buffers and controls is...
ICP Standards – Relevance, Application and Metrology
The measurement of cations and anions is of critical importance in almost every industry. Detailed examples of these industries, whilst not exhaustive, are presented in this paper and this list is steadily growing. The level of user expectation in terms of sensitivity...
Measurement of Conductivity | Conductivity Standards
Introduction The measurement of electrical conductivity in liquid or conductivity measurement as it is more commonly known is an extremely popular and important measurement. It is a measurement that is performed daily in a wide range of industries. The correct...
Nitrosamine Standards
Nitrosamines are formed from the chemical reaction between amines and nitrogen containing products that include nitrides, nitrogen oxides or nitrous acids. The products are present extensively in the environment and in the alimentary tract of humans and mammals. These products are now classified as known carcinogens. The products may only be present in various matrices in parts per billion (ppb) or parts per trillion (ppt) levels, so a high degree of sensitivity and high-quality standards are necessary to detect their presence. Reagecon offers ready-to-use, neat (powder form) and multi element standards for nitrosamine analysis.
Obtaining Accurate Conductivity Measurement
Conductivity is an extremely common analytical technique. Due to the simplicity of the equipment required, it can be measured quickly and cheaply. However, there are a number of factors that need to be taken into account to ensure that these measurements are accurate and fit for purpose so that decisions made based upon conductivity test results are correct …
Obtaining Accurate Readings with TDS Meters
Total Dissolved Solids (TDS) is commonly used for assessing the concentration of impurities in water in areas such as environmental monitoring and boiler and cooling tower water monitoring. There are 2 main methods for testing TDS: Contents of the Guide 1. Take an...
Organic Standards Product Range | Reagecon Poster
Reagecon has an extensive range of Organic Standards. These include very commonly used standards and some less widely used but equally important products such as: Volatile Organic Compounds (VOCs) Phenol Standards Polycyclic Aromatic Hydrocarbon Standards (PAHs)...
pH Buffer Solutions, Selection, Use, Application and Metrology
What is a pH Buffer? pH buffers are solutions that are used to resist changes in pH when an acid or a base is added to the solution. The pH of the solution changes very little over the specified buffer range of the pH buffer. pH buffer standards covering the full pH...
Phthalate Standards – Relevance and Application
Because of their extensive use in plastics, phthalates of various types are now ubiquitously present in the environment. The fact that they can migrate into foodstuffs, can bioaccumulate, are toxic and poorly degradable means that they are of concern from a health and safety perspective. To protect consumers, many methods have been developed to qualitatively and quantitatively detect and measure phthalates, with chromatography being the method of choice. Irrespective of the method used, there is a requirement for high quality, well characterised phthalate standards. Reagecon offers a significant range of such standards which can be used for calibration, verification, quality control and method validation of chromatographic equipment.
