The Chromatography Beast

“It looked like a Medusa,” said Farah Mavandadi. “I was scared of it.”

Mavandadi, a senior product manager at Bio-Rad, was not describing a monster in a nightmare or a creature seen from a diving bell, but rather a research-scale chromatography system. Sprawling over a lab bench, instead of snakes the system had bunches of electronic cables and fluidic tubing that writhed and tangled around its various components.

Despite resembling an unholy mashup between Rube Goldberg and Jason and the Argonauts, this system was highly valued by the researcher who had wrangled it together, lovingly making each complex connection and hand-coding each component into the analytical software. The reason? Flexibility. Despite its messiness, the researcher could rearrange her system to get the most efficient fluidic path, to have right kind of detector in place, or make any other tweak in order to perform the best possible separation. Between having an “easy” instrument and having one she could change as her chromatography needs required, this researcher chose to face “Medusa.”

But what if, reflected Mavandadi, researchers could add, remove, and reconfigure modules in their chromatography systems without performing the Labors of Hercules? Answering this question became the driving principle behind developing the NGC™ medium pressure chromatography system. This installment of the Chromatography Chronicles will delve into Bio-Rad’s push to bring modularity and “plug-and-play” design to chromatography. But first, watch postdocs Tomas and Janna put their chromatography systems through their paces in a friendly but feisty face-off.

Three Great Webinars for Better Chromatography

Are you feeling frustrated by chromatography? Do you wish that there was someone there to help you with your chromatography needs instead of just telling you what to do and walking away? If so, join Bio-Rad scientists for three fantastic webinars on a myriad of chromatography subjects. The first three webinars include:

  • chromatography 101 (given June 5th but playback is available for webinar registrants
  • Ion Exchange Chromatography: An Overview Choosing a matrix, parameters affecting resolution, the latest products available, and tips for better chromatography (June 20)
  • Size Exclusion Chromatography: General principles, choosing the best matrix for your samples, the latest products available, and tips for successful separations (July 23)

Next Generation Chromatography is Finally Here

After months of cheesy YouTube videos, (some were actually quite funny…see “Stand Up Against Downtime” and “Break Out of the Cold Room“), Bio-Rad had finally launched the eagerly anticipated NGC™ Medium-Pressure Chromatography Systems.

The NGC family of chromatography systems offers multiple system configurations, optional upgrades, and a common software platform. Suitable for analytical and preparative chromatography. For a complete system tour visit www.bio-rad.com/ngc.

Bio-Rad Laboratories has also made available a series of videos explaining how to use the particulars of the system. To see the full list of video tutorials visit the NGC™ Next-Generation Chromatography YouTube Playlist.

Here’s a sample video to get you started:
