Dec 17, 2015 · “The choice of solvents that can dissolve a polymer is typically very limited, compared to small molecules, and limits the type of HPLC method you can use. Also, polymers contain a distribution of chain lengths, which often will result in multiple peaks or a very broad peak during the HPLC separation.
EquipNet is the world’s leading provider of used HPLC systems and HPLC accessories. Our exclusive contracts with our clients yield a wide range of used HPLC systems from a number of respected OEMs, including Aijiren, Waters, Hewlett Packard, Perkin Elmer, Hitachi, Shimadzu, Dionex, and many others.
When there are additives the specific gravity of the resulting polymer may be higher or lower than that of the base polymer depending on the specific gravity and proportion of additive used. It is to be noted that the specific gravity of some of the polymers (polypropylene (PP) and (PE)) is less than 1.0, which is a drawback when working with
TradeIndia is organising India's first virtual event on Covid-19 Essential Products. In the absence of physical events, the Covid-19 essential expo gives an opportunity to manufacturers, suppliers and exporters to digitally connect with global buyers, build new business partnerships and get qualified leads.

HPLC Stationary Phases for a Wide Range of Separations. For more than 35 years, Hamilton Company has developed and manufactured pressure-stable, polymeric polystyrene-divinylbenzene (PS-DVB) HPLC columns that are used in most of the world’s top chromatography labs.
The reaction can also produce polymer to a significantly higher molecular weight than the melt phase process, which is suitable for extrusion blow moulding applications. For this type of application polymer with Mn greater than 35,000 is required. On achieving the required Mn, the pellets are cooled to temperatures 40. PET PACKAGING TECHNOLOGY
Designed for use with HPLC instrumentation and organic synthesis applications, our HPLC solvents undergo rigorous specification testing to ensure suitability for these uses.
This website is a a free, online resource for selectivity data and tools for High Performance Liquid Chromatography. The current database contains column parameters for over 500 reversed-phase HPLC columns characterized using the Hydrophobic Subtraction Model of reversed-phase selectivity.
Microvolume inserts are sold in both glass and polyproylene materials. Polypropylene inserts are recommended for pH-sensitive samples, greater solvent compatibility, biological samples, and ionic samples becasue of the material′s inertness.
Several styles are offered including flat bottom, concial inserts with a top spring or a bottom spring, and concial without springs.
