| The stability of the AGP column has been tested using bumadizon (an acidic drug) as a test compound. A total of 30.5 liters of mobile phase (10% isopropanol in phosph. buffer pH6.0) was pumped through the column. During the test 2030 samples of bumadizon were injected. The two chromatograms below are the first and the last obtained in the test. No significant changes were observed. |
