Protein and Particulate Removal That’s Fast, Painless, and Effective

Resprep PPT3 CRMRestek’s line of Resprep® sample preparation products has expanded to include 96-well protein precipitation (PPT) plates. New Resprep® PPT3 96-well plates offer highly efficient protein removal with built-in, drip-free membrane and 3-way versatility for filtration, so you can prepare serum, plasma, and other biological samples using the name you have long trusted for quality, cleanliness, and performance.

Resprep® PPT3 96-well plates offer consistently greater than 99% protein removal and drip-free, in-well protein precipitation for a minimum of 24 hours—with no fear of backflushing or contamination. A dual-layer membrane with different porosities in each layer prohibits clogging and speeds up filtration, and using our recommended solvent-first method streamlines sample preparation even further.

Resprep® PPT3 96-well plates are also incredibly versatile. The 2.0 mL deep wells are suitable for mixing by vortex or pipette, and these 96-well plates can be used to increase throughput in general filtration applications. Best of all, PPT3 96-well plates are compatible with all common filtration devices: vacuum manifold, positive pressure manifold, and centrifugation.

Abstract:

Restek’s Chris English sat down for an interview with chromatography icon Robert Sternberg, who received his PhD in electrochemical biosensors and worked on the development of a glucose sensor in an artificial pancreas for 10 years before joining an emerging field of astrobiology. This started a 37-year career in analytical chemistry that would play a critical role in the success of the Cassini-Huygens, Curiosity, ExoMars, and most recently the Rosetta mission. His areas of interests are in the characterization for organic molecules in extraterrestrial environments. Dr. Sternberg and the European Space Agency (ESA) have been working with Restek, using our columns and Pro ezGC® software on their missions, for over 15 years. With the Rosetta spacecraft and its Philae lander making the news recently, Chris caught up with Dr. Sternberg to discuss his work.

Abstract: Carrier gas changes for SimDist methods, such as ASTM Method D7213, can be easily implemented in your daily process. Using MXT®-1HT SimDist columns and EZGC® method translation software, helium-based SimDist methods can be easily translated to alternative carrier gases while maintaining ASTM Method D7213 requirements.

Restek Encourages Bellefonte Middle Schoolers to Think Outside the Beaker

Nearly 30 students will attend an after-school science education program at Penn State, thanks to a donation by the Bellefonte-based business.


For the next five weeks, students from Bellefonte Middle School will participate in Think Outside the Beaker, an after-school science program hosted by Penn State’s Science Outreach Office—thanks to a donation from Restek.

“We’re proud members of the Bellefonte community and are excited to offer this opportunity to our local middle schoolers,” Restek President, Bryan Wolcott, said. “As a technical company, we love science, and we love being able to encourage youth who share our passion!”

On Mondays, from September 21 through October 19, students from grades 6 to 8 will be bused from Bellefonte to nearby Penn State to learn about biology, chemistry, physics, astronomy, neuroscience, and more from University scientists, engineers, and students. The program is held yearly by Penn State’s Science-U.

“We’re thrilled to have Restek as a partner in offering this program every fall and are having a blast fostering the next generation of STEM professionals,” Michael Zeman, Director of Science Outreach, said.

By participating in the brand-new workshop miniseries, students will focus on a variety of STEM topics (Science, Technology, Engineering, Mathematics) while improving their critical thinking, creativity, problem-solving, and communication skills.

Electronic Cigarette Solutions and Resultant Aerosol Profiles

Abstract: Electronic cigarettes (e-cigarettes) are growing in popularity exponentially. Despite their ever-growing acceptance, their aerosol has not been fully characterized. The current study focused on evaluating e-cigarette solutions and their resultant aerosol for potential differences. A simple sampling device was developed to draw e-cigarette aerosol into a multi-sorbent thermal desorption (TD) tube, which was then thermally extracted and analyzed via a gas chromatography (GC) mass spectrometry (GC-MS) method. This novel application provided detectable levels of over one hundred fifteen volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs) from a single 40 mL puff. The aerosol profiles from four commercially available e-cigarettes were compared to their respective solution profiles with the same GC-MS method. Solution profiles produced upwards of sixty four unidentified and identified (some only tentatively) constituents and aerosol profiles produced upwards of eighty two compounds. Results demonstrated distinct analyte profiles between liquid and aerosol samples. Most notably, formaldehyde, acetaldehyde, acrolein, and siloxanes were found in the aerosol profiles; however, these compounds were never present in the solutions. These results implicate the aerosolization process in the formation of compounds not found in solutions; have potential implications for human health; and stress the need for an emphasis on electronic cigarette aerosol testing.
