Anion exchange chromatography with both indirect photometric detection (IPD) and unsuppressed conductivity detection modes were used for the separation and detection of inorganic anions. Salt of phthalic acid has been used as an eluent for several anions both with IPD and conductivity detection.

In this work new derivatives of L-ascorbic acid (Vitamin C ) have been stynthezized .

    Atenolol ion selective electrodes have been prepared based on phosphotungistic acid using many plasticizers which were:Di-butylphosphate (DBP), Tri-butylphosphate (TBP),o-nitrophenyloctylether (ONPOE) and Di-octylphthalate (DOP).The properties of the prepared electrodes have been studied including: slope, concentration range, detection limit, life time, and pH effect.The electrodes no.
