Improved column stability Spherical sorbents for liquid chromatography are not new, nor are claims of higher efficiency and ease of packing. The significant advantage of spherical 5μηη sorbents, however, is their stability and long life in the packed column.
Extensive testing has proven that Spheri-5 reverse phase columns have a longer shelf life, and survive a greater number of sample injections and solvent changes than columns packed with 5μηη ir regular shaped sorbents. Proven high performance Spheri-5 columns are indi vidually computer tested. The test conditions and chromatogram are included with each analytical c o l u m n or cartridge.
You can expect twice the plate count of our regular 1û>m products, at only a 20% higher price. Order from a Brownlee Labs distributor, or write for more information: Brownlee Labs!
