XTerra Columns

Thank you for ordering a Waters XTerra

®

column. XTerra packing

materials are synthesized using Waters Hybrid Particle Technol-
ogy. XTerra particles contain both inorganic (silica) and organic
(organosiloxane) components sharing the advantages of both. Hybrid
technology allows for the high efficiency of separation and improved
pH stability when compared to Silica based reversed phase packing
materials. The manufacture of XTerra columns starts with ultrapure
reagents to control the chemical composition and purity of the Hybrid
particle. Every manufacturing step is conducted within narrow toler-
ances and each column is individually tested. Certificates of Batch
Analysis and Column Efficiency are provided with each column.

We recommend the use of Waters Sentry

guard columns to extend

the life of your column and protect it from contaminants.
