Triple detection GPC/SEC combines measurements from multiple detectors to offer not only increased amounts of data, but also increased amounts of information, which is made available by the combination of different detectors (and unobtainable using individual detectors separately). The theory of triple detection GPC/SEC is described here.

This application note describes the analyses of a variety of aqueous (water-soluble) cellulose derivatives using the OMNISEC triple detection system and the subtle, yet distinct differences between these different derivatives that can be parsed out by the OMNISEC system

The investigative power of multiple detectors. Here, we describe the analysis of a semi-purified protein mixture containing β-amylase. Step-by-step, we show how different properties of the proteins elicit a specific response in each detector and how coupling this data can be qualitatively and quantitatively evaluated.

Benthoctopus sp gets overly familiar with Alvin’s robotic manipulator arm at 2,300 meters down in the Gulf of Mexico.

Extraction of air sampling filters for the determination of dioxins using BUCHI’s SpeedExtractor E-914

A 2015 Innovation Award-winning “fastGC” module enhances proton transfer reaction time-of-flight analyzer performance by adding an optional near real-time chemical pre-separation step. Here’s the story behind its development.

The traditional approach of designing experiments by changing one factor at a time is outmoded.

Can a new slippery surface for Raman scattering open the door to routine single molecule detection?

The molecular weight, molecular weight distribution and size of two common polymers are measured using SEC-MALS 20. Results from SEC-MALS and conventional calibration are compared and discussed.
