New Reference Standards for Accurate trans Fat Determination

trans fats reference standards imageryGrowing concern about the impact of partially hydrogenated oils on human heart health makes accurate data on trans fat content in foods critical for protecting consumers. New reference standards from Restek help you ensure that your lab is generating accurate results. In addition to a derivatization agent, we also offer internal and calibration standards of verified composition and stability. Paired with an Rt-2560 GC column, these new reference standards help ensure accurate determination of trans fat content in foods and edible oils, and they are suitable for AOAC and AOCS methods.

Restek Wins Company of the Year

Restek was awarded Company of the Year from The Pennsylvania/Delaware Chapter of The ESOP Association during its annual conference on September 14 in Scranton, PA.

This is the second time Restek has won the award, having also received the honor in 2007. Over the years, many ESOP conferences have included a Restek employee as a session speaker, and two employees have also won the chapter’s Employee-Owner of the Year award.

“Employees at Restek are fully engaged in the ownership culture. They also have done wonderful work in advocacy both in Pennsylvania and in Washington D.C. Restek is very deserving of this award and should be a top contender to win the national award at The ESOP Association meeting next May,” Jeff Gelburd, Chapter President, said. The PA/DE chapter is one of 18 that provide educational services and resources to its members across the country.

An employee stock ownership plan (ESOP) is a business structure in which the employees of the company are also owners. Restek transitioned to 100% ESOP on Dec. 31, 2008.

“Restek is a family-oriented company that is owned by its employees. While our business is scientific, our culture is all about teamwork and taking care of our fellow employees so that we can better serve our customers and our community. We are honored to be recognized by the ESOP Association and encouraged to continue serving others through our business, our charity, and our ESOP advocacy,” said Bryan Wolcott, Restek President and Head Coach.

With over 450 employees across the U.S., China, Japan, Italy, France, Germany, and the UK, Restek has earned a reputation in the scientific community for unbeatable Plus 1 service and innovative, top-quality chromatography products. Analysts rely on Restek products to monitor the quality and safety of air, water, soil, food, pharmaceuticals, chemicals, and petroleum.

Recently, Restek, along with the PA Center for Employee Ownership, taught students from South Hills School of Business and Technology in State College, PA, about employee ownership and the benefits of working for an employee-owned company. Students from three majors—business, information technology, and graphics—took a tour of Restek’s facility, attended an in-lab chromatography demonstration, and received education about ESOPs and Restek—as well what Restek does for the community and the environment.

In addition to this most recent recognition, Restek has been named one of PA’s best places to work several times and has also been named one of The Wall Street Journal’s Top Small Workplaces.

Struggling with EtG/EtS matrix interferences?

A Raptor EtG/EtS column is your solution! Typical methods for EtG and EtS analysis have several limitations: poor resolution from matrix components, long run times that limit sample throughput, and short column lifetimes. Restek has developed a new Raptor EtG/EtS column that consistently retains and resolves EtG and EtS from matrix interferences, providing accurate, reliable results injection after injection. Reliable performance and long column lifetime make this column ideal for alcohol consumption monitoring by high-throughput labs. Paired with Restek reference standards and our fast, 4-minute, dilute-and-shoot LC-MS/MS method, the Raptor EtG/EtS column allows you to analyze EtG/EtS samples with confidence.

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation.

Abstract:

Methods for monitoring alcohol consumption biomarkers EtG and EtS are generally limited by poor retention and coelution with matrix interferences, as well as by long analysis times and short column lifetimes. The dilute-and-shoot EtG/EtS LC-MS/MS analysis developed here using the novel Raptor EtG/EtS column easily resolves EtG and EtS from matrix interferences, providing consistent, accurate results for high-throughput labs testing human urine samples for alcohol consumption.

Abstract:

By properly conditioning new columns and employing Restek’s EtG/EtS method for sample prep and analysis, high-throughput labs testing human urine samples for these alcohol consumption biomarkers can ensure accurate, consistent results with fewer column changes.
