2-Dimensional
Chromatography for Macromolecular
Molar Mass and Structure Determination
REVIEW: A primer
in 2Dimensional Chromatography
In 2D chromatography, different
techniques are essentially combined to achieve a higher degree of
separation. eg. coupled GPC-HPLC; HPLC (to separate functional
groups) and GPC to
separate according to
size.
2D is useful for analysis of complex polymer systems like
polymer blends, copolymers, branched polymers and proteins.
Where to purchase
a 2D system?
PSS can provide you with all of the
necessary components, including software, the column
chemistry,
valving and transfer loops, do the installation, and show you how to
operate the 2D-LC system. You need to provide or purchase the LC instrument
for the
1st dimension, (injector and gradient pump), and a pump for the
2nd
dimension (GPC separation), as well as a detector, (usually an
ELSD,
but a UV detector is also used on occasion).
Analytical Services
PSS offers the development of 2-D
applications and performs the analysis for you, with our special
software for data acquisition, quantitative interpretation and data
plotting. Please forward a sample form and
or fill out our
