For the best separation efficiency, you can't beat Davisil® chromatographic adsor bents for T L C and C C . Narrow particle size range is the reason. Each of our ten Davisil grades consists of parti cles that are precisely sized — not too small be cause that would slow separation, and not too large because that would weaken resolution. With the right Davisil grade, you'll get optimum performance and consistency...on the
bench, in pilot plant replication, and tor com mercialization.What's more,Davisil is produced right here in America, by the world leader in silica gel technology and manufacturing. So you can count on Davison for the quantities you need, and the consistent quality that chromatography demands, f o r a broad se lection of narrow-range DAVISON adsorbents, talk to us.
