Page 14 - Shimadzu Nexera Series

Faster Analysis Without Sacrificing Precision

It is important to use the most appropriate column in your LC system to achieve the highest efficiency and most accurate
chromatograms. The Shim-pack series consists of a range of columns designed with the increased capabilities of the Nexera in mind. The
superior ruggedness of Shim-pack columns ensures a long lifetime even with demanding sample matrices.

Shim-pack Velox ™

The superficially porous particle (SPP) technology allows for optimum separation and analysis times. The range of column types available
enables you to choose the most appropriate column for each application.

SP-C18 C18 Biphenyl PFPP HILIC
USP classification L1 L1 L11 L43 L3
Stationary phase Sterically protected C18 C18 Biphenyl Pentafluorophenyl propyl None
Particle size (µm) 1.8, 2.7, 5 1.8, 2.7, 5 1.8, 2.7, 5 1.8, 2.7, 5 2.7
*To maximize column lifetime, columns with 1.8 µm particle size are
recommended for use with a pressure under 80 MPa.

Shim-pack XR-ODS II & III
™
Although the Shim-pack XR-ODS II has a particle size of 2.2 µm, it can be used up to a pressure of 60 MPa, making it appropriate for a
wide range of analyses. The particle size of the XR-ODS III column has been reduced to 1.6 µm. With a maximum pressure of 100 MPa, it
achieves high separation even with a short column length.
These columns are suitable for shortening analysis times while taking full advantage of the high separation power of UHPLC.

USP classification L1 L1
Stationary phase C18 C18

Shim-pack GIS/GIST/GISS
The Shim-pack GIS/GIST/GISS series lineup includes columns with particle sizes ranging from 5 µm, appropriate for HPLCs, to 2 µm,
appropriate for UHPLCs. With a variety of substrates available, they are ideal for method development.

GIS Series: HPLC columns packed with a high-purity silica gel material as a base. With high particle uniformity to secure the mobile
phase path, these columns are ideal for low-pressure analysis.
GIST Series: An increase in the inertness of the silica results in improved peak shapes and ruggedness. Can be used in pH 1–10
environments. Easy to use for a wide range of chemicals and environments.

GISS Series: Adding to the advantages of the GIST series, a faster elution time has been achieved to provide even sharper peaks.
