#HPLC-"pure silica" produced via the polymerisation of tetraethylorthosilicate; uniform associated silanol groups are produced .......
#HPLC Remember.. if you are out by 1% in your mobile phase composition.. that can equal a HUGE 5% change in retention time
#HPLC - ...... ENCAPPING is used to reduce the no. of isolated silanols and only 30% of available silanols are capped!!!
#HPLC-"base deactivated" silica is acid treated to reduce metals which are responsible for increasing the acidity of the silica surface
#HPLC -How to overcome the problem of peak tailing: solution 2 - use "base deactivated" silica!
