Electrochemical detectors & analyzers
For over 25 years, Antec is known for its electrochemical detectors (ECD), providing unprecedented sensitivity in HPLC analyses. In almost any kind of application in conventional HPLC, UHPLC, Micro-, Capillary- and Nano HPLC, ECD is extremely selective and sensitive. It is applied routinely in a number of analyses such as neurotransmitters, (poly)phenols, carbohydrates, and a large variety of pharmaceutical compounds.
Electrochemical reactors for MS & synthesis
Using Electrochemistry (EC) as a reaction technique before the MS allows the analyst to mimic natures’ REDOX reactions in almost any analytical field. Many chemical and catalytic reactions (wet chemistry, Fenton, etc.) can be mimicked in a controlled manner in the electrochemical cell simply by applying a voltage potential. A large number of biochemical reactions such as enzymatic, micorbial, aquatic, photolytic, etc, can be simulated without biological interferences (e.g. cell matrix, plasma, urine, soil, etc.) and the generated REDOX products can be easily detected by MS, making EC/MS a real biomimetic tool with substantial cost and time savings compared to in-vivo or in–vitrotechniques.
DryLab Software for HPLC Method Development
DryLab is the revolutionary HPLC method development and optimization software that predicts chromatograms under a much wider range of experimental conditions than would ever be possible in the laboratory. With DryLab you can quickly and easily determine exactly how your separation behaves as you simultaneously vary multiple method parameters, such as pH, temperature, buffer concentration, and many more. Anybody developing HPLC methods who wishes to optimize complex samples and to economize resources spent developing and running methods will benefit from the many advantages offered by How does DryLab work? Define Method Goals and Run Input Experiments The beauty of DryLab is that with data generated from only 2-12 input experiments, DryLab predicts resolution and retention times for millions of unique, virtual chromatograms. The first step to using DryLab is to define your analytical target profile (ATP) and let DryLab help you choose your systematic approach and initial method conditions. Then simply run your input experiments and upload them as *.cdf files, which is the universal format for chromatographic data systems.ting the impact of small fluctuations on up to six critical separation parameters. You can determine which parameters exert the greatest influence on the method and therefore must be strictly controlled…

Chromatography columns, vials, caps and accessories
A group of independent distributors concluded that mergers and acquisitions in the chromatography consumables industry have limited the offerings available to the laboratory scientist – meaning less choice and less competitive pricing. Aiming to provide more options and let local independent distributors operate on a more level playing field, the idea of a buying group was born in the form of Chrom4.

As an authorized distributor, MD Scientific can offer Tosoh Bioscience’s comprehensive line of high and low pressure columns to meet your purification needs. For more details and price, please contact MD Scientific at info@md-scientific.dk or +45 7027 8565 HIGH PERFORMANCE LIQUID CHROMATOGRAPHY High Performance Liquid Chromatography (HPLC) and Ultra High Performance Liquid Chromatography (UHPLC) use liquid mobile phases to transport the sample components through a column packed with a solid material; the stationary phase. The “mode” of chromatography is usually defined by a combination of a certain stationary phase type with a certain mobile phase type. In order to generate a chromatogram that is suitable for qualitative or quantitative purposes, bonded phase chemistry, column dimensions, and particle and pore sizes are parameters that need to be optimized. TSKgel Chromatography Columns Tosoh Bioscience offers a comprehensive line of TSKgel (U)HPLC columns for use with conventional and UHPLC systems to meet your purification needs. The TSKgel product line include columns in nearly every mode of HPLC, including Size Exclusion, Ion Exchange, Reversed Phase, Hydrophobic Interaction, Affinity, and Normal Phase/HILIC.

PuriFlash columns from Interchim
Download column guide (PDF-file) puriFlash® Columns – The separation tools Manufactured by Interchim under proprietary packing “Accurate Bed Technology™ Purification results equivalent to a Prep LC column Compatible with any Flash system Stable @ up to 22 bars* /308 psi puriFlash® Columns – The separation tools – choose the right media Media selection requires consideration of sample volume, the nature of the analyte, analyte concentration and the inherent properties of the sorbent itself. See list of columns on Interchim’s website. Polymer loading capacities are higher than silica, however, silica sorbents exhibit greater selectivity. Silicas: Silica & bonded silica are rigid supports that do not shrink or swell with solvents. The silica surface can be easily modified, this creates a potential for a large selectivity for purification from hydrophobic to hydrophilic interactions. The pH stability of bonded silica is limited, typically to within the range of 2 to 7.5, this is chemistry dependant. Interchim offers more than 20 different silica based selectivities. Our sorbents take advantage of our ultra pure spherical silica, and this achieves greater reproducibility, and establishes optimized sample recoveries. Polymers: Polymer sorbents are very stable from pH 1 to 14, they exhibit high loading capacities allowing for the…
