J.T.Baker® HPLC–9012 Acetonitrile Provides a Competitive Alternative for Customers Performing Routine HPLC Applications

Mallinckrodt Baker, a business unit of Covidien (NYSE: COV), a leading global provider of healthcare products, has introduced a new grade of acetonitrile to match the quality requirements for customers performing routine high-performance liquid chromatography (HPLC) applications and analysis.

Mallinckrodt Baker’s new J.T.Baker® HPLC-9012 Acetonitrile rounds out the company’s offering of acetonitrile products specifically developed for HPLC and LC/MS applications. The new product extends Mallinckrodt Baker’s ability to provide customers with options that closely match performance and quality requirements across multiple applications. This helps ensure a more cost-effective use of acetonitrile in the laboratory.

J.T.Baker® HPLC-9012 Acetonitrile is application-optimized and function-tested specifically for use in isocratic HPLC (refractive index or UV/Vis) and routine gradient HPLC (UV/Vis) analysis, as well as spectrophotometry, ion chromatography, biopharmaceutical purification and quality control testing.

J.T.Baker® HPLC–9012 Acetonitrile is gradient elution tested at 254 nm and meets ACS specifications for general use, liquid chromatography suitability and UV spectrophotometry. In addition, Mallinckrodt Baker’s manufacturing expertise in purification, packaging and analytical testing ensures strict quality control to provide the lot-to-lot consistency required in HPLC methods and applications.

The new 9012 HPLC grade is intended to complement Mallinckrodt Baker’s existing J.T.Baker® HPLC Ultra Gradient–9017 Acetonitrile, a higher purity grade of acetonitrile, which is designed for more advanced HPLC methods and applications such as trace concentration or environmental analysis, using evaporative light scattering or fluorescence detection.

“In response to the recent worldwide shortage of HPLC acetonitrile, our expanded offering helps customers reduce their supply chain and quality risks, and also improve their ability to manage costs,” said Russell Thorpe, Global Marketing Director for Laboratory Products at Mallinckrodt Baker. “We’ve tailored our HPLC and LC/MS solvent product lines to closely align with the needs of our customers so that they can select exactly the right grade of acetonitrile. So whether they are performing routine, gradient HPLC testing or advanced research on today’s most demanding instrumentation, Mallinckrodt Baker has a product to optimize instrument performance and help them meet their financial objectives.”
