XTerra Shield RP18 Column, 125Å, 5 µm, 4.6 mm X 50 mm, 1/pk

With the XBridge Shield RP18 Columns, you will achieve greater base separation. The XBridge Shield RP18 Columns, which use the patented Shield Technology to achieve extremely symmetrical and efficient peaks, show reduced silanol interactions with basic analytes. The 'Shielding' effect, which results in enhanced peak shape, is caused by the deactivation of basic analytes. This is significantly superior to commonly available C18 lab equipment, which has poor peak symmetry due to secondary interactions with basic chemicals caused by weak cation exchange with residual surface silanols.

With the XBridge Shield RP18 Columns, you can spend less time and have more confidence generating robust separations to fully exploit the power of pH.

The XTerra Shield RP18 Column is made from a high purity methyl hybrid material that is made in a similar way to high-purity silica, with one important difference: the XTerra material is made from the mixed condensation of two high purity monomers rather than one. The XTerra Shield RP18 Column's Hybrid Particle Synthesis is done with tetraethoxysilane (TEOS) and methyltriethoxysilane (MTEOS). The XTerra Shield RP18 Column, like all Waters lab equipment, is built to ISO 9001 standards, guaranteeing that each step is completed to the highest standards and with the tightest tolerances possible.

Using the XBridge Shield RP18 Columns, optimize the test conditions that are critical to obtaining a successful separation. The XBridge Shield RP18 Columns provide an alternative selectivity by being able to operate over a wide pH range and with a number of solvents.

Depend on the XTerra Shield RP18 VanGuard Cartridge, 125Å, 5 µm, 3.9 mm X 5 mm, 3/pk for the continued optimal performance of your analytical lab equipment. The cartridge is made using the exact materials that the column is made from, making them an ideal fit. It works by preventing any chemical or particulate material from entering the mobile phase. This enhances the life of the column while improving the accuracy of the analytical results.
