We see from your search that you're looking for information on the term "Evaporative Light Scattering",
and we have a large number of manufacturers' news releases and technical articles here on Laboratorytalk which will be of interest.
Let me be your guide.
Start with
the news release Varian HPLC system promises speed and flexibility from
Varian, which we summarised at the time by saying "When the 920-LC is used with short, highly efficient Varian HPLC columns packed with sub-3micron particles, chemists will be able to achieve shorter analyses, better peaks, and better quality
data".
Several months prior to that,
we featured the news release Booklet explains triple detection GPC/SEC from
Viscotek Europe: "Technique combines a concentration detector (refractive index or UV-Visible), viscometer and light scattering detector acting in concert, with each providing complementary but different information".
In September 2006, we covered the news from SeQuant
concerning its Zic-Hilic column
- take a look at Determination of positive and negative counterions
which says: "Simultaneous determination of positive and negative counterions in pharmaceutical preparations using Zic-Hilic column containing an extremely versatile zwitterionic stationary phase".
Take a look also at the news release from Parker Balston - Analytical Gas Systems, Cutting nitrogen costs for laboratory applications,
as well as HPLC detectors are USB-compatible from ESA Biosciences,
and Free seminars in London and Manchester from Kinesis.
