Chromatography 17
UHPLC Method Development Software on Show at Pittcon 2018 The Molnár-Institute for applied chromatography has made progress this year to connect DryLab®
4 from to some popular Chromatography Data Systems (CDS’s) and instruments (such as Waters, Shimadzu,
Thermo) to automate the development of UHPLC methods. This is a great help for users, as they don’t need to manually set up the 12 methods, which are typically required by DryLab®4 for its unique 3D-modelling of the critical resolution of UHPLC separations.
Stop by Pittcon booth 1763 to discuss innovative strategies for improving the efficiency and success of cutting-edge HPLC through Molnár-Institute’s revolutionary method development software, DryLab® 4,
and learn how to shorten your method development time from 1-3 months to less than 1 week. If you want your data system to support automated modelling, visit the Molnár-Institute for applied chromatography for more information and get an evaluation opportunity for your method optimisation work.

New Application Book Offers Expertise in GPC Analysis
Gel permeation chromatography (GPC) is a valuable and well-established tool for the chemical industry when it comes to the determination of the molecular weight and its distribution of polymers.
GPC can determine several important parameters. These include number average molecular weight (Mn), weight average molecular weight (Mw), Z weight average molecular weight (Mz), and the most fundamental characteristic of a polymer, its molecular weight distribution. These values are important, since they affect many of the characteristic physical properties of a polymer. Differences in these values can cause significant differences in the end-use properties of a polymer.
A new application book compiles various examples of ambient and high temperature GPC analysis for a broad range of polymers performed using the Tosoh EcoSEC GPC systems and TSKgel columns.

SFC Column Kit for Fast Screening of Samples
The Kromasil SFC kit is shipping for fast evaluation and efficient method development of samples under SFC conditions. The Kromasil SFC kit contains four columns including the following phases: 2-ethylpyridine, cyano, diol and silica. These columns are based on the trusted, high performance, state- of-the-art spherical Kromasil silica, giving peace of mind to those working in the research and discovery.
Designed for fast separations using 2.5 µm particle size technology, laboratory scientists are able to analyse a wide range of substances, from non-polar to strongly polar compounds with the columns included in the kit. Medium and high-throughput laboratories looking to improve efficiency find this kit a vital tool to achieve the required goals.
With 30 years of stationary phase manufacturing and packing expertise, Kromasil continues deliver performance products to customers in the pharmaceutical, food and beverage, clinical and environmental industries.

New Immobilised Lux®
Chiral LC/SFC Selector Delivers Broad Enantioselectivity
Phenomenex Inc has expanded its Lux chiral LC/SFC column family with new immobilised Lux 5µm i-Amylose-1 and Lux 3µm i-Amylose-1 media. During the manufacturing of Lux immobilised media, a chemical crosslinking is formed between the polysaccharide and silica support, resulting in a robust column that can withstand a wide range of strong solvents including DMSO, THF, Ethyl Acetate and DCM. This robustness allows for potential increases in enantioselectivity as new strong solvent systems can provide more mobile phase options during method development. It also allows scientists to keep samples dissolved in strong solvents like DMSO/DCM.
With the addition of the new Lux i-Amylose-1 and previously introduced i-Cellulose-5 media, Phenomenex now offers two immobilised polysaccharide chiral stationary phases (CSP) in analytical and preparative formats. These two robust chiral options combine with six Lux coated chiral stationary phases (Amylose-1, Amylose-2, Cellulose-1, Cellulose-2, Cellulose-3 and Cellulose-4) to deliver a wide and complementary range of enantioselectivity for even the most difficult chiral separation projects under normal-phase, reversed-phase, polar-organic or SFC separation modes.
“Amylose tris (3,5-dimethylphenylcarbamate) is one of the most popular polysaccharide CSPs in use today for enantiomeric separations,” explained Simon Lomas, Strategic Marketing Manager for Phenomenex. “The addition of an immobilised version of this popular phase adds versatility and extends the possible uses of the product.”
The new Lux 3µm i-Amylose-1 is ideal for LC/SFC analytical work and chiral screening, while the larger diameter Lux 5µm i-Amylose-1 can be used for analytical and purification work as it is available in pre-packed Phenomenex Axia™ preparative columns. Primary applications for this new phase include small molecule pharmaceuticals and their impurities as well as chiral pesticides in the environmental and agricultural markets. Phenomenex continues to expand its Lux chiral media offering, which now contains eight different Lux medias, to meet these needs. The company also offers free chiral screening services with greater than 90% success rates from its PhenoLogix application development group, along with over 2,000 chiral applications online that are easily searchable by compound structure or name at
