T&T GPC/SEC: A Development in High Temperature (HT) GPC/SEC
Size exclusion chromatography (SEC) is a powerful method for analysing molar mass distributions. It is essential, that the GPC/SEC eluent is appropiate for the analyzed polymers. Some kinds of…

T&T GPC/SEC: _Absolute or true molar masses for macromolecules - Mass spectrometry as a new solution
GPC/SEC separates macromolecules based on their hydrodynamic volume and therefore allows to separate an ensemble of chains with different lengths into small fractions. Primary information from GPC/SEC…

T&T GPC/SEC: _Copolymer Analysis in GPC/SEC 3: 2-dimensional Chromatography
A problem in GPC/SEC, that cannot be solved by using any detection technique, is that the method may suffer from limited chromatographic resolution. Combination of different separation techniques…

T&T GPC/SEC: _Faster Results
Traditionally GPC/SEC is a slow technique. A typical, non-optimized GPC/SEC run with 3 analytical columns and a precolumn needs about 45 to 60 minutes to be completed. This limits the number of…

T&T GPC/SEC: _GPC/SEC columns - Dos and Don'ts
GPC/SEC columns, like all LC columns, have a finite life time and in order to get the best performance and a long life time the columns have to be treated properly. However, there are many ways to…

T&T GPC/SEC: _GPC/SEC-Viscometry - a Versatile Tool for Structure Determination and More
In comparison to other GPC/SEC detectors as light scattering detectors or UV detectors, viscometers need more care. It takes longer times to get a stable baseline after changing from one solvent to…

T&T GPC/SEC: _Improving the reliability of GPC/SEC light scattering and viscometry results
On-line light scattering and viscometer detectors increase the information depth of GPC/SEC data and allow the measurement of absolute molar masses and structures. However, even a set-up with advanced…

T&T GPC/SEC: _Is this real? Unexpected peak shapes
GPC/SEC samples show often broad and/or multimodal peaks, that are not baseline separated and look strange to users of other chromatographic techniques. However, although many weird looking peaks are…
