Spherisorb SAX Column, 80Å, 5 µm, 4 mm X 250 mm, 1/pk
Depend on the Waters Spherisorb SAX Column to give you outstanding flexibility in optimizing methods and reducing solvent consumption. The silica-based column is designed to be general-purpose, durable, and high-efficiency chromatographic columns.
With the Waters Spherisorb SAX Column, you can consistently meet the quality standards required for liquid chromatography. Like all other lab equipment made by Waters, the Spherisorb SAX Column is manufactured in the dedicated Waters chromatography chemistry manufacturing plant under the strictest cGMP, ISO 9002 conditions. Using the Waters Spherisorb SAX Column, you will get the most critical performance features: column efficiency, peak symmetry, column lifetime, and column-to-column reproducibility.
Rely on the Spherisorb SAX Column to get the best column stability and highest efficiency along with best peak symmetry as the Spherisorb SAX Column is designed to understand and address the effects of all process parameters such as slurry solvent choice, packing pressure time, temperature, flow rate, and slurry volume.
Protect your analytical column by using the Spherisorb SAX Guard Cartridge, 80Å, 5 µm, 4.6 mm X 10 mm, 3/pk. The guard cartridge extends the life of your analytical column by removing all particulate and chemical contaminants from the mobile phase. Thus, it is the ideal lab equipment as it extends the column’s lifetime and ensures that you always get consistent and reliable performance from the column.

When Will The Spherisorb SAX Guard Cartridge Need To Be Replaced?
To ensure that the Spherisorb SAX Guard Cartridge serves a long time, use a Waters Spherisorb guard of matching chemistry and particle size between the injector and main column. This is important to protect the main column while not compromising or changing the analytical resolution. Changing the guard columns needs to be done at regular intervals as determined by the sample contamination. An indication that the guard column needs to be replaced is when system backpressure steadily increases above a set pressure limit. Another indication is the sudden appearance of split peaks or other changes in chromatographic performance.
