The Quality of the Analytical Result
The Quality of the Analytical Result is a technical paper which has been produced by John Barron, Technical Director of Reagecon, and provides information on how to obtain a result that is fit for purpose and prove that such a result is of high-quality. Many factors...
The Role of Accreditation’s in the Production and Use of Analytical Volumetric Solutions (Titrants)
The acquisition and maintenance of accreditations and certifications, has and continues, to play a major role in the commercial production, of high quality analytical volumetric solutions. For a producer of such materials, accreditations and certifications should be...
The Selection and Use of Instruments for Accurate Conductivity Measurement
Conductivity instruments should only be used if they can produce measurements of the required quality and format, are suitable for their measuring environment and are user-friendly. This paper describes all of the key characteristics of conductivity instruments, enabling analysts to assess if conductivity instruments meet their requirements.
The Selection, Use, Care and Maintenance of Sensors for Accurate Conductivity Measurement
Abstract As is the case with all measurements, the selection of appropriate sensors and their correct use is essential for the accurate measurement of conductivity. This paper outlines the different types of conductivity sensors that are available to the analyst and...
Titrants (Analytical Volumetric Solutions & Indicators)
Reagecon produces an extensive range of high-quality Titrants (Analytical Volumetric Solutions). These products are standardised and factorised against a primary standard, where such a primary standard exists, and certified to a specification of ± 0.1% in the case of common aqueous titrants or ± 0.2% in the case of less commonly used Titrants or Non-aqueous Titrants.
Total Acid / Total Base Number (TAN/TBN) Standards
Reagecon has a complete offering of standards and reagents for both TAN and TBN, irrespective of the method used. These include titrants, standards, buffers and electrolytes for the major ASTM methods. The suite of products extend to titrants required for back titration and the potassium hydrogen phthalate used to re-standardise or re-factor the titrants
Total Acid Number (TAN) and Total Base Number (TBN)
This short video provides viewers with an overview and short summary of Total Acid Number (TAN) and Total Base Number (TBN).
TAN and TBN are critical parameters in lubricating oil and are also measured in a wide range of other petrochemicals. The measurement is a quantification of the acidic or basic impurities, is tested by non aqueous titration and the units used to express both TAN and TBN are milligrams/gram of potassium hydroxide. There are a number of specified methods and a change in method may result in a change of test result. However, the most commonly used methods are those specified by ASTM.
Total Organic / Inorganic Carbon Standards (TOC / TIC)
Reagecon manufactures two ranges of Total Organic Carbon (TOC) and Total Inorganic Carbon (TIC) Standards for use when calibrating all types of TOC analysers, irrespective of brand. TOC Standards are manufactured using high purity USP or NIST raw materials in accordance with USP guidelines.
Total Organic Carbon (TOC) / Total Inorganic Carbon (TIC) Standards
This short video provides viewers with an overview and short summary of Total Organic Carbon (TOC) and Total Inorganic Carbon (TIC) Standards.
Total organic carbon (TOC) is an indirect measure of the quantity of organic material present in a solution.
TOC measurements may be performed in a laboratory setting, others on-line in a plant or effluent stream or using portable instrumentation in a wide variety of settings. In all cases, the level of organic carbon needs to be corrected for measured carbon dioxide emanating from inorganic materials.
Turbidity Standards
Reagecon’s Turbidity Standards for ratio and non-ratio instruments are composed of suspended polymer microspheres. These Turbidity Standards remove the handling, stability and accuracy problems associated with traditional Formazin Turbidity Standards. These products are extremely accurate (± 1%), NIST traceable and US EPA approved and have guaranteed stability throughout their entire shelf life, even after opening the bottle
