Колонки ВЭЖХ Symmetry

Symmetry™ Columns exceed the standards for HPLC column
performance. To ensure their optimum performance, they are packed
with high-purity silica using stringently controlled manufacturing
processes. No other silica-based LC column brand can match
the column-to-column and batch-to-batch reproducibility of
Symmetry Columns.

■■Symmetry C18 and C8 Columns deliver maximum reproducibility
■■SymmetryShield RP18 and RP8 Columns provide superior peak shape
■■Symmetry300 C18 and C4 Columns offer high recoveries of peptides and proteins

Goals of Sample Preparation

Successful sample preparation for most analytical techniques (HPLC, UPLC, ™LC-MS, UV, GC, etc.)
has a threefold objective. It needs to provide the sample component of interest:
■■  In solution
■■  Free from interfering matrix elements
■■  At a concentration appropriate for detection or measurement

Waters™ Sample Preparation Solutions for quantitative analysis make it easy to deliver a sample that is reproducible with
high recovery and free of interferences. Based on simple, logical workflows that produce clean samples through selective
separations, Waters Sample Preparation Products maximize sensitivity, increase throughput, and enable the development of
robust methods.
