LCGC Magazine is pleased to announce the addition of Douglas E. Raynie to its editorial advisory board.
Raynie is an associate research professor in the Department of Chemistry and Biochemistry at South Dakota State University (Brookings, South Dakota). Prior to joining SDSU, he worked for 11 years as a senior scientist in Procter and Gamble’s research division.
Raynie’s research interests are in the field of sustainability and green chemistry. His two major areas of research are analytical separations and bioprocessing, using supercritical fluids and related technologies. One common theme to both of these research areas is the use of nonconventional solvents, including supercritical fluids, ionic liquids, and deep eutectic solvents. His analytical separations research includes high-resolution chromatography, chromatographic sample preparation (accelerated solvent extraction, superficial fluid chromatography, solid phase microextraction, and solid phase extraction), chromatography theory, green analytical chemistry, and problem-based learning in analytical chemistry. His active projects in bioprocessing are centered on pretreatment strategies for the conversion of lignocellulosic biomass to bioenergy or high-value materials.
Raynie received his PhD from Brigham Young University (Provo, Utah) under the direction of Milton L. Lee. His undergraduate degree is from Augustana College (Sioux Falls, South Dakota), with majors in chemistry and biology.
Sustainable Green Solvents in Microextraction: A Review of Recent Advancements
March 27th 2024Conventional sample preparation can be time- and resource-consuming, and a green analytical methodology can be a game-changer for scientists, in addition to facilitating selective and sensitive separations.
Transferring Methods to Compact and Portable HPLC
February 14th 2024The current trend in laboratory equipment design is the miniaturization of laboratory instruments. Smaller-scale HPLC instruments offer benefits that cannot be matched by analytical-scale equipment, especially in the areas of portability, reduced fluid volumes, and reduced operating costs. Yet, the miniaturization of laboratory equipment has brought with it a unique set of challenges, including transferring methods to compact LC. Capillary LC expands the use of LC to applications not currently done using conventional LC in a wide array of application areas, including pharmaceutical, food and beverage, petrochemical, environmental, and oil and gas. Greg Ward, Axcend’s CEO wrote, “Customers want an HPLC system with a small footprint, low flow rates and green chemistry.” Join his podcast where he shares method transfer in these application areas.
High-Throughput Analysis of Volatile Compounds in Air, Water, and Soil Using SIFT-MS (Apr 2024)
March 27th 2024This study demonstrates high-throughput analysis of BTEX compounds from several matrices (air, water and soil). Detection limits in the single-digit part-per-billion concentration range (by volume) are readily achievable within seconds using SIFT-MS, because sample analysis is achieved without chromatography, pre-concentration, or drying. We also present a calibration approach that enables speciation of ethylbenzene from the xylenes in real time.
