Chromatography 17 New, Simple to Use Flash Purification Interface Introduced
Biotage, a leading global supplier of solutions and technology for analytical, medicinal and peptide chemistry, is pleased to announce the introduction of Isolera™ Assist, a new intelligent user experience for their flash purification systems.
Isolera™ Assist provides a structured guide for users resulting in consistent purification conditions and an intelligent way to select optimal cartridges based on crude sample mass and TLC data. Isolera™ Assist is available to all Isolera instruments, making each system a simple to use purification instrument. Isolera™ Assist simplifies the setup procedure of a purification run, incorporating intelligence that guides the user to utilise the system in the most economical way to quickly and reliably isolate pure compounds. The patented gradient prediction and gradient optimisation tools predict gradient shape and sample loading as well or better than an experienced chemist.
“Using Isolera Assist is like having a senior chemist/mentor with 30 years of experience watching over your shoulder. Helping you produce successful purifications with a minimum of risk, time spent and cost. With Isolera™ Assist, we bring the benefits of our Accelerated Chromatographic Isolation (ACI™) system to the next level, integrating both in a simple to use setup procedure for every chemist, regardless of their experience level,” said Biotage Flash Purification Product Manager, Tobias Nordin.

Short Thread Vials from Kinesis are designed with an overwind-barrier that provide an optimal seal and compression between the cap, septum and vial. The sealed vial offers the sealing and performance characteristics of a crimp top vial and the versatility and convenience of a threaded vial. This is achieved by incorporating a definite stop point into the design of the vial, preventing over tightening of the cap. SureStop Vials remove all doubt about the degree of tightening necessary for optimal sealing.
Reduce Sample Evaporation and Extend Autosampler Needle Lifetime SureStop®
SureStop Vials offer a consistent seal, independent of the amount of torque applied when closing the vial whether by the same or different users. This gives optimal septum compression across the opening of the vial. This design allows the positioning of the closure to be consistently aligned with the vial, producing a more cylindrical vial profile, which in turn improves autosampler recognition, handling and compatibility. SureStop Vials are compatible with the majority of autosamplers on the market.
In comparative studies with other 2ml vials, SureStop Vials provided the lowest solvent loss due to evaporation and the lowest standard deviation. For more information on SureStop Vials, please visit

37607pr@reply-direct.com ADVERTORIAL UK Made Gas Chromatograph from only £5400
The 200 Series Gas Chromatograph from Ellutia is an extremely compact, energy efficient yet powerful analysis tool. Designed and manufactured by Ellutia in the UK the 200 Series GC offers all the analytical performance of a much larger conventional system but with a footprint of just 41 x 32 cm and power consumption of just 800 VA.
The 200 Series GC is a single channel instrument that comes installed as standard with a split/splitless injector and full electronic carrier gas control. A Choice of detectors are offered including FID, TCD, ECD and FPD, allowing for most applications to be run. The oven can accommodate capillary columns up to 60m in length as well as packed columns using the optional adaptors.
The 200 Series GC column oven is heated by a unique, innovative and award winning heater design. The flow through heat exchanger unit means the design of the GC could be kept extremely compact and energy efficient without sacrificing performance. The oven can be temperature programmed with up to 5 settable ramps up to maximum temperature of 300?C.
A Range of accessories are available including Liquid and Headspace autosamplers, gas sampling injection valves, integration software and hardware and PC method download Software. Are available to further enhance the capabilities.
The 200 Series GC starts at only £5400 for an instrument with an FID Detector and further discounts available for educational establishments.

Analysis of Diacetyl and Other Vicinal Diketones
(VDK’s) in Alcoholic Beverages Vicinal diketones (VDK) are naturally produced compounds in the fermentation process. The monitoring of VDK levels is of great importance as the concentration of these compounds can greatly alter the flavour of a beverage. VDK’s produce a butter like flavour in the beverage so are undesirable in lighter beers that want a clean crisp taste, but are actually wanted at higher levels in wines to give a smoother taste and feel. The most commonly monitored VDKs are 2,3-butanedione also known a Diacetyl and 2,3-pentanedione also known as Acetyl Propionyl. VDK’s are typically found in the 0-100ppb range in beers, and can be anywhere from 100 to 5000ppb in wine.
The Rise in popularity of craft beer has seen a dramatic rise in the number of smaller independent breweries. Many of which cannot justify they cost and space of large expensive GC systems. A method has been developed using the Ellutia 200 series Gas Chromatograph and the Ellutia EL-2100 Head-Space autosampler to provide an offering that can address the analysis at a lower entry price.
The System is able to analyse the compounds of interest down to the required low ppb levels.
The Ellutia 200 series GC and EL2100 autosampler can provide a simple lower cost solution to VDK analysis allowing breweries with smaller budgets the ability to perform this useful analysis. For Further information please visit:
