ODS-H Example 1. The absence of active silanols in kromega Select is illustrated by this standard test mixture which includes both pyridine and phenol. The lack of peak tailing clearly demonstrates the absence of metallic impurities. 1. Pyridine, 2. Phenol COLUMN kromega Select ODS-H 5µm DIMENSIONS 15cm x 4.6mm MOBILE PHASE 40:60 Acetonitrile:Water TEMPERATURE 40°C FLOW RATE 1 ml/min DETECTION UV at 254nm ODS-H Example 2 Neutral silanol groups can still occasionally cause problems with certain classes of compound. Theobromine, theophylline and caffeine are particularly prone to this effect. In kromega Select this effect is elimated by full end capping. 1. Theobromine, 2. Theophylline,

Many compounds such as polyphenols interact irreversibly with the active sites on silica based reversed phase materials. In the case of kromega Select ODS-H this problem does not occur, which makes it possible to analyse problematic compounds such as in the ODS-H Example below.
