General description

Visit our Sensor Applications portal to learn more.

Application

Calcium ionophore V (K23E1) may be used in fabricating calcium on to the waveguide sensor to understand the selectivity of the specific ion and also measure its concentration.
Selected application examples

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Employed in highly calcium-selective membrane electrodes exhibit excellent selectivity toward alkali and earth alkali ions (log KPOT(Ca2+,Mg2+ = -5.0)) and extremely high lipophilicity (log PTLC ionophore: 14.6); Neutral ionophore used in a calcium-selective optode
