Breaking Down the Features of Thermo Fisher Scientific ORION Ionic Strength Adjusters, Thermo Fisher Scientific Scientific 950210
Specifications
The Thermo Fisher Scientific ORION Ionic Strength Adjusters, Thermo Fisher Scientific Scientific 950210 is specifically designed to enhance the ionic strength of weak acidic solutions, which is crucial for the accurate functioning of certain electrochemical sensors. The product is sold individually, with each unit containing one pint (1 PT) of the adjuster solution. This volume is quite substantial for laboratory use, meaning a single bottle can last a considerable amount of time depending on the frequency of use and sample volumes.
The primary specification is its intended application: to increase the ionic strength of solutions, particularly those that become dilute as ions leave the sample, such as in chlorine or bromine analysis. This adjuster is ionically based, meaning it introduces ions into the solution to create a more conductive and stable environment. This increased ionic strength helps to minimize liquid junction potentials and ensure that the activity coefficient of the measured ion remains relatively constant.
Crucially, this specific model is indicated for use with Carbon Dioxide electrodes. This is a key specification that dictates its suitability for particular analytical tasks. For comparison, other ionic strength adjusters might be formulated for different types of electrodes or sample matrices. The Thermo Scientific No.: 950210 is the unique identifier for this product, ensuring proper ordering and inventory management within a lab setting.
