Understanding Biosensors Biosensors are devices used in identifying a selective range of analytes (specific substances that require detection). The device comprises two elements: a biological component and physicochemical detector (also known as the transducer). Each biosensor functions by converting biological responses into readable electrical signals. This process is achieved by generating signatures proportional to the concentration of the analyte. The...

6 Reasons to Initiate Change Control with Manufacturers Making a year-end decision to change an established manufacturing partnership in the life science, diagnostic, medical device, and pharmaceutical industries is one of the most difficult decisions you will ever make in your organization. I am a 30-year veteran of the life sciences industry, currently serving as Founder/CEO of AG Scientific, Inc...

Magnesium Ionophores for Ion Selective Electrodes Magnesium (Mg) is a metallic element and one of the most abundant minerals found on Earth. The mineral does not exist naturally on its own, often making up a part of dolomite and magnesite deposits. Magnesium is essential in the sustenance of life and is located within the core structure of chlorophyll, the green...

Carbonate Ionophores for Ion Selective Electrodes Carbonates (CO3(2−)) are a vital ingredient in organic chemistry and are some of the most widely scattered minerals found within the Earth’s crust. Carbonate salts are formed when a substance reacts with carbonic acid (H2CO3). Carbonate ionophores can be useful for measuring concentrations of such carbon species. There are diverse types of carbonates commonly...

Ionophores are a chemical species that reversibly bind ions. Lithium ionophores are a lipophilic variant of these species, which means that they may be combined with lipids and are fat-soluble. What is Lithium? Lithium is a metallic element (Li) with 2 naturally occurring forms of isotopes, namely lithium-6 and lithium-7. Lithium has become a popular battery option due to its...

Ion-Selective Electrodes (ISE): An Introduction Ion-selective electrodes have a wide variety of industrial and research uses. They offer a comprehensive method in testing the level of activity of ions contained within aqueous solutions. This is a necessary process to determine the electrical potential (conductivity) of a substance or solution, through potentiometry. What Are Ion-selective Electrodes? Ion-selective electrodes are also known...

7 Procurement Problems in the Chemical Industry Procurement is at the heart of any large organization. Finding you the raw materials needed for the very best price is what keeps your business ticking over. In the complex and nuanced world of the chemical industry, suppliers who tick all the boxes are few and far between. Here are 7 common procurement...

Decoding Chemical Grades For Your Lab Handling chemicals is serious business. In order for researchers to create the solution they need for an experiment, they have to choose reagents of the right chemical grades. Choosing an insufficient grade could have unanticipated affects when added to a system. When a chemical reagent is graded by its manufacturer, customers are able to...
