ion selective electrodes การใช้

• The hydrogen-ion selective electrode is a standard hydrogen electrode.
• Free nitrate ions in solution can be detected by a nitrate ion selective electrode.
• The selectivity of macrocyclic ligands can be used as a basis for the construction of an ion selective electrode.
• The glass electrode ( and other ion selective electrodes ) should be calibrated in a medium similar to the one being investigated.
• Simple ions are often measured with ion selective electrodes, which let one type of ion through, and measure voltage differences.
• Originally LiDCO s first technology used a lithium ion selective electrode to accurately measure cardiac output by lithium dilution in arterial blood, the technique was the inspiration for the company s name.
• The polymer Ion Selective Electrodes were able to determine the concentration of ions by measuring the change of electric potential within the sensor, which is separated from the wet chemistry cell by an ion selective membrane.
• Ionophore means " ion carrier " as these compounds catalyze ion transport across hydrophobic membranes such as liquid polymeric membranes ( carrier-based ion selective electrodes ) or lipid bilayers found in the living cells or synthetic vesicles ( liposomes)
• Although it is certainly a sound precaution for the determination of sulfide with an ion selective electrode, it might however hamper the development of the blue color if the freshly formed methylene blue is also reduced, as described here above in the paragraph on redox indicator.
• This value is calculated from Br  " and CTA + ion selective electrode measurements and conductometry data by using literature data for micelle size ( r = ~ 3 nm ), extrapolated to the critical micelle concentration of 1 mM . However, K?varies with total surfactant concentration so it is extrapolated to the point at which micelle concentration is zero.
• "' 1-( 2-Nitrophenoxy ) octane "', also known as "'nitrophenyl octyl ether "'and abbreviated "'NPOE "', is a chemical compound that is used as a matrix in fast atom bombardment mass spectrometry, liquid secondary ion mass spectrometry, and as a highly lipophilic plasticizer in polymer membranes used in ion selective electrodes.
