Nova-Pak C18 Guard-Pak Insert, 60Å, 4 µm, 10/pk

Make use of the Nova-Pak C8 Guard-Pak Insert to safeguard your analytical HPLC column by filtering out chemical and particle materials from the mobile stream. It is vital to note that the sorbents used in Waters Guard-Pak inserts are the same as the sorbents used in Waters HPLC columns and cartridges. As a result, it is critical to utilize an insert with the same sorbent as the column or cartridge you are using to get the best results. The product indicated here can be used with a µPorasil 4 µm particle size column or cartridge.

The Waters Nova-Pak C18 columns are general purpose, silica-based, reversed-phase C18 columns that are based on 4 µm particle technology. Compared to a 5 µm column, Nova-Pak columns offer higher resolution, more efficient separations, and faster chromatography. This is why it is essential to protect your Nova-Pak C18 columns so they continue to provide you with outstanding analyses.

Nova-Pak bonded phases' 4 µm compact particle size provides greater resolution, more efficient results, and faster chromatography by allowing users to use shorter columns, decreasing solvent usage, or longer columns to resolve even the most complicated mixtures.

The Nova-Pak C8 Guard-Pak Insert, like all of our manufactured products, is prepared with ultra-pure chemicals under the most stringent conditions. Our cGMP manufacturing facility's extensive QC procedures ensure batch-to-batch consistency.

When using the Nova-Pak C8 Guard-Pak Insert with high-performance/low-volume columns, you may notice some efficiency loss. When utilizing the guard holder and insert, the same care should be taken as when employing analytical columns. Only use miscible eluents to avoid precipitation inside the insert.
