This short video provides viewers with an overview and short summary of Analytical Volumetric Solutions, Titrants and Indicators.
The principle of all titrimetry involves the determination of the quantity of the reagent of known concentration the (titrant), that is required to react completely with an unknown analyte. Volumetric titrimetry involves measuring the volume of the solution of known concentration the (titrant) consumed, gravimetric titrimetry measures the mass of the reagent consumed and coulometric titration measures a direct electrical current of known magnitude that consumes the analyte. In coulmetry, the time it takes to complete the electrochemical reaction, is the measurement.
This short video provides viewers with an overview and short summary of Chemical Oxygen Demand (COD) Reagents & Vials.
Chemical oxygen demand also called COD is widely used as a measurement in wastewater and natural waters. COD is defined as the amount of a specified oxidant that reacts with a sample under controlled conditions and is expressed in mg/l.
This short video provides viewers with an overview and short summary of Colour Standards.
The measurement of colour is now an exact science. This is due to the simultaneous evolution of high-quality instrumentation, and high-quality standards to calibrate and control this instrumentation.
Colour measurement is also a highly sophisticated science and accurate measurement is necessary in almost every industry. Such industries range from the Pharma and Cosmetics industries, right through to both potable and polluted waters, Beverages both alcoholic and non-alcoholic, Food and many other industrial segments.
This short video provides viewers with an overview and short summary of Conductivity Standards. It briefly describes how Conductivity Standards are measured and used.
The measurement of electrical conductivity in liquid or conductivity measurement as it is more commonly known is an extremely popular and important measurement. The correct performance of the measurement is dependent on using high quality equipment, in particular a good sensor used in the correct manner and in the right environment. It is particularly important that the sensor is calibrated correctly and in a timely manner and that the test is correctly controlled.
This short video provides viewers with an overview and short summary of Cyroscope Standards. It briefly describes how Cyroscope is measured, the different types and applications of Cryoscope along with what industries predominantly use Cyroscope Standards.
One application of the change in freezing point is to measure the concentration of water in a solution, which is known as Cryoscopy.When water is added to a solution such as milk, the freezing point is elevated towards zero degrees Centigrade and differs markedly from that of a normal, undiluted milk sample.
This short video provides viewers with an overview and short summary of Density Standards.
Density, also called Mass Density, is a fundamental physical property of a material. It is defined as the mass per unit volume at a specific temperature. Mathematically, density is expressed as mass/volume where the SI units are kg/m3 but g/cm3 or g/ml are also widely used. The density of a material varies with temperature and pressure.
This short video provides viewers with an overview and short summary of Flame Photometry Standards.
Flame Photometry is particularly suitable for Alkali and Alkaline Earth metals by exploiting the fact, that these metals are excited at a lower temperature than most other metals. When these excited metals return to their normal state, they emit electromagnetic radiation. The wavelengths of this radiation are easily isolated by optical filters and converted to an electrical signal, the magnitude of which is a direct function of the concentration of a particular metal in a sample, standard or control material.
This short video provides viewers with an overview and short summary of ICP-MS and ICP-OES Standards.
The measurement of cations and anions is of critical importance in almost every industry. The extent of these industries is almost limitless but can broadly be classified as: Industrial Engineering, agriculture, food, pharmaceutical, mining and geology, medicine and medical device, petrochemicals, metal processing, environmental.
Forty years ago methods of choice for measuring cations and anions included colourimetric measurement, flame photometry, ion selective electrodes and atomic absorption spectroscopy. All of these technologies are still widely used but nowadays where greater sensitivity, versatility or efficiency are required, ICP-OES, ICP-MS, ion chromatography and XRF are widely used.
This short video provides viewers with an overview and short summary of Melting Point Standards.
The Melting Point of a substance is the temperature at which the crystalline phase of the substance changes to its liquid phase. Melting point is defined as the temperature at which the solid and liquid are in equilibrium at a total pressure of 1 atmosphere. Unlike the volume change that accompanies the vaporization of a liquid, the change in volume that takes place upon the melting of a solid is very small.
This short video provides viewers with an overview and short summary of Reagecon’s Organic Standards offering.
Chromatography is the collective term for a set of laboratory techniques used for the separation of mixtures. The mixture in other words the sample is carried by a liquid or gas and is then separated into its respective components as a result of the different affinities of the components as they flow through a stationary liquid or solid phase, known as a column. Three of the main techniques of analytical chromatographic analysis are Gas Chromatography, High Performance Liquid Chromatography and Ion Chromatography. So, to define chromatography, in simple terms, it is the separation of compounds based on their affinity for a bonded stationary phase.
