A simple digital image processing technique is examined to recognize the phase separation of a chemical process. traditional aqueous-organic hexane (1) - water (2) acetic acid (3) system and its alternative aqueous two-phase PEG (1)-K2HPO4 (2)-water was selected as model with or without polymer. In this technique, monitored recorded using webcam set up processed on computer an subtraction proce...

a rapid, simple and sensitive high-performance liquid chromatography method was developed for determination of ciprofloxacin in plasma by means of ultraviolet detection. ofloxacin was used as an internal standard and separation carried on a novapak c18 column using a mobile phase of 0.01 m phosphate buffer (ph =2.6): methanol (82: 18 v/v). extraction of drug was performed from plasma by liquid-...
