Ion Exchange Flashcards
Uses the compounds…..
Chemical properties.
Used medically for the…
Separation of haemoglobin compounds from HbAlc
Used to soften water by
Cation exchange of sodium ions with magnesium and calcium ions.
The SP is an…
Ion exchange resin.
One ionic species, the solute, is….
Substituted for another in the SP.
Exchange of positive ions is…
Cation exchange.
Exchange of negative ions is….
Anion exchange.
IEC can analyse any ions, including….
Organic ions.
Ions are eluted in order of strength of binding, therefore the….
Weakly bound ions are eluted first.
The interactions of ions on the SP depend on differences in….
Charge and charge density of the ion.
Can analyse….
Multiple ions.
Automated IEC is…
Rapid.
Multiple ions elute from IEC, retention times must be compared with…..
Standards which have been ran through the same type of resin.
Chemical prep may be needed to…
Separate diff anions and cations.
Separates ions in the sample by their exchange….
Of ions on the column.
Sulfur dioxide analysis by IEC is more….
Sensitive than titration.
Sulfur dioxide analysis: type of column is…
A negative, anion exchange column.
Sulfur dioxide analysis: the SP is
HCO 3-
Sulfate ions are eluted by addition of more…
HCO3- ions
Sulfur dioxide analysis: the concentration of sulfate ions is proportional to the….
Conductivity of the solution and can be measured with a conductivity meter.
