Free Capillary GC Tips and Tricks Seminars


High Sensitivity GPC Triple Detector System for


Polymer & Protein Characterisation The new SEC-3010 triple detector system from Dorton Analytical Ltd sets a new standard for high performance characterisation of polymers and proteins using Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC).


Crawford Scientific, in conjunction with Agilent Technologies, are staging a series of seminars across the UK informing customers about a myriad of tips and tricks that will improve their productivity when operating Capillary GC systems.


Hints on GC troubleshooting, column selection, how to move to ‘fast GC’ painlessly and methods employed to obtain best peak shape, resolution and detection limits are covered by the experienced speakers from Crawford’s and Agilent.


The seminar is intended to be the most productive event that chromatographers will attend this year and early registration is recommended.


Each seminar lasts for a half day and registration is free. All registrants are entitled to lunch, free giveaways and special promotional offers.

The SEC-3010 triple detector system is a complete GPC system comprising pump, autosampler, viscosity/refractive index detector, multi-angle light scattering detector and ParSEC enhanced software.


The patented design of the SEC-3010 Viscosity/Refractive Index Detector allows the simultaneous determination of the refractive index and the intrinsic viscosity of a polymer solution. With its sophisticated technology, it overcomes the disadvantages usually encountered when using coupled detectors. The asymmetrical bridge circuit allows 80% of the sample to reach the measuring arm compared with 50% in conventional instruments, thus increasing sensitivity by a factor of 2. The direct integration of the refractive index measuring cell in the analytical arm of the viscometer allows the determination of the intrinsic viscosity and the refractive index in exactly the same sample segment.


The Multi-Angle Light-Scattering Detector is a modern, intuitive, 7-angle detector for the comprehensive characterisation of macromolecular compounds. Its innovative technology offers the highest quality and precision in the absolute determination of molecular weight. The sample is illuminated by a very precise, temperature-controlled laser beam. The scattered light is collected by a highly-sensitive CCD detector which transmits the data to the ParSEC software.


ParSEC Enhanced provides the complete software solution for comprehensive polymer characterisation via multi-detector GPC. The software records and evaluates the data from various combinations of GPC detectors. It calculates the specific and intrinsic viscosity, the Mark-Houwink coefficients, the absolute molecular weights, Mn, Mw, Mz, Rg, the Mw/Mn structure coefficients and the branching parameters from the scattered light data. All analytical methods, raw data, calibrations, results and sample information are stored in a single database, allowing very easy archiving and retrieval of data.

Fused-Core® HALO®


particle technology


for hyper-fast and super-rugged HPLC columns


Not like other fast HPLC columns.


HPLC columns rival the speed and resolution of columns packed with sub-2 µm particles, but generate less than half the back pressure. HALO columns can turn almost any HPLC into an ultra-fast HPLC. Now available as a polar-embedded phase–HALO RP-Amide.
