App Notes

In gel permeation chromatography (GPC), just like all chromatography modes, the heart of the separation lies in the quality, applicability and selectivity, or resolution, of the column.

The need to increase the use of low valued co-products derived from the processing of sugar beets has prompted the investigation of the structure of the pectin extracted from sugar beet pulp.

For polymeric materials the molar mass and molar mass distribution play a vital role in the determination of mechanical, bulk, and solution properties

New roles and applications in the areas of science and technology are continuously being found for synthetic polymers.

Isocyanates are both highly reactive and highly toxic low molar mass chemicals.

This Application Note presents data obtained from a series of poly-b-alkylalanoids synthesized by Dr. Li Jia, which were obtained using living alternating copolymerization of N-alkylaziridines and carbon monoxide5.

Analyzing blood serum for opioids, cocaine and their metabolites commonly involves manual or partly-automated sample preparation steps such as protein precipitation, solid phase extraction, evaporation and derivatization before GC/MS or LC/MS determination. The process can now be fully automated.

Hydrogen generators are now becoming an essential component in many laboratories with greater gas consumption levels. Most people are aware that hydrogen gas is produced from electrolysis of water, but is it as simple as that and why are generators so expensive?

GC-MS based pesticide analysis utilizing a new and fast QuEChERS sample preparation procedure

Larger porous shell particles with narrow particle size distribution - used in reversed-phase U/HPLC analysis of peptides and proteins - provide increased efficiency per unit pressure drop, which can be taken advantage of by increasing peak capacity or traded in to reduce analysis time.
