First steps to fast separations

June 2923 -- Pure Essential Chromatography System: First steps to fast separationsJune 2023, Flawil, Switzerland - BÜCHI Labortechnik AG, a leading provider of laboratoryequipment, has added the Pure Essential Chromatography system to its portfolio. Thisinstrument serves as the ideal introduction to automated flash chromatography. Benefittingfrom an easy-to-use, compact, and modular design that allows the system to grow with yourneeds. The most basic of all chromatography systems is the traditional open-column setup. It is howmost people are introduced to chromatography, similar to the setup used bychromatography's inventor Mikhail Tsvet. The setup is very basic, involving a glass columnwith two open ends (sometimes, in small laboratories, a burette is used instead of a column).At the bottom of the column is a stopcock to control the solvent flow directed to the collectionflask. The entire process is gravity fed; therefore, it is slow and inefficient and requiressomeone to perform each step of the separation process manually. Over the years, the technique for separating compounds of synthesis or extraction mixtureshas been vastly improved; however, many modern systems are complex and expensive andoffer advanced features that some users do not require. The Pure Essential Chromatographysystem has been specifically developed to fill this gap in the market. At its heart is a strong50 bar pump that allows for high flow rates. The pump rapidly moves the solvent and samplethrough the stationary phase. The instrument allows for automation of the process thanks toan intuitive software control which also ensures fast and reproducible results. Only a fewclicks are required to program a method or adapt parameters on the fly. Prepacked flashcartridges simplify the setup, as there is no requirement for manual column packing. Theentire system is efficient and uses small particle sizes for higher-resolution results, all whilereducing solvent consumption.

The Pure Essential Chromatography system has been designed as a modular system with asmall footprint, allowing the setup to grow with your needs. A highly sensitive UV detector orfraction collector can be added to the powerful Pure Chromatography C-900, a controlledpump. Safety is also a key feature of the Pure Essential Chromatography system which isequipped with a pressure sensor and benefits from a solid design with steel pump heads androbust accessories built for the rigors of daily use. Everything is easily accessible on theinstrument, making maintenance a breeze.

Simplicity results from intelligent design and years of experience, and the Pure EssentialChromatography system is a shining example of a dedicated focus on perfecting theessentials. The instrument is ideal for academia or labs that require a bespoke setup for aparticular workflow. "The Pure Essential Chromatography system is super easy to use,without any bells and whistles. It benefits from a small footprint and attractive price as well; itis the perfect way to enter the preparative chromatography instrument world when used tousing open columns," said Dr. Ruedi Hartmann, Director of Business Areas & VerticalMarkets at BÜCHI Labortechnik.

The Pure Essential Chromatography system completes BUCHI's comprehensive range ofpreparative chromatography systems. BÜCHI Labortechnik AG remains dedicated to offeringsolutions catering to all budgets and workflows of academic, pharmaceutical, chemical, andbiotechnological industries.

Modernizing pharmaceutical assay testing

Titration is an important analytical method that is widely used for pharmaceutical assay testing. However, many USP monographs still refer to manual visual endpoint titration methods. Such manual procedures are not only tedious to perform but also more prone to human error. A free white paper by Metrohm summarizes the steps involved converting an existing manual titration procedure to semi-automated or automated titration procedures and gives three practical examples. Traditionally, the reaction...

New MT-5 Alkalinity Titration System - Simple and Smart!

MANTECH's MT-5 marks our evolution to bring simple water quality analyzers to municipal and industrial users. These important users, operating the drinking and wastewater treatment plants, have long suffered with multiple scattered analysis stations to do their critical jobs, and having to "write down" results on bench sheets. The operators try to remember: Is the pH meter calibrated? Is that glass buret with alkalinity titrant purged?, etc. With the NEW MANTECH Pro software, operators and...

Better reproducibility of results, compliance with GxP, and more

Many laboratories are still using manual titration to perform their routine analysis. However, glass burets are delicate to handle, volumes are difficult to read, and exposure to hazardous liquids pose a threat to the user's health. A short video describes and explains these and other reasons why laboratories should switch from manual titration to using an automatic system with a digital buret and a potentiometric end point detection.As titration is one of the oldest methods of chemical analysis, many...

Eco Dosimat – new, universal tool boosts productivity in the laboratory

A great deal of time is spent in laboratories every day on repetitive routine task such as preparing standard solutions, controlling syntheses and/or performing manual titrations. With the new Eco Dosimat, much of this time can be saved, as these tasks are performed faster, easier, and much more reliably.The Eco Dosimat combines a digital buret, an integral magnetic stirrer, a touch sensitive display, and GLP compliant documentation in one compact device. There are many routine tasks, where the Eco Dosimat...
