Dr. Byrdwell is a Research Chemist at the Food Composition and Methods Laboratory, part of the Beltsville Human Nutrition Research Center, part of the Agricultural Research Service, the research branch of the U.S. Department of Agriculture in Beltsville, Maryland |
My research focuses on applying
the latest technology in Liquid Chromatography/ Mass Spectrometry to questions
of biological and agricultural importance. The primary focus of my research
is analysis of fats and the fat soluble Vitamin D in foods
and in agricultural products using high performance liquid chromatography-mass spectrometry (HPLC-MS).
Dr. Byrdwell utilizes three mass spectrometers interfaced to liquid chromatographic systems via atmospheric pressure ionization interfaces. We have Three techniqes in use: Atmospheric Pressure Chemical Ionization Mass Spectrometry (APCI-MS), Atmospheric Pressure Photo Ionization MS, APPI-MS, and Electrospray Ionization MS, ESI-MS. Dr. Byrdwell was the first author to report simultaneous use of two mass spectrometers employing APCI-MS and ESI-MS in a "Dual Parallel Mass Spectrometer" arrangement for analysis of lipids. Studies are underway to expand this initial work. 
It's Here! It's Here! Dr. Byrdwell's NEW book is now available ONLINE !!! www.MendingTheSacredHoop.com!  Mass Spectrometry and Related Techniques is available from AOCS Press (http://www.aocs.org/catalog/) www.HPLC-MS.com! Preparation of the first report of the Unit Simulacrum as a construct for Mass Spectrometry is underway! Keep an eye out at Byrdwell.com to continue to follow developments regarding this exciting discovery! |

| Have a Look Inside Dr. Byrdwell's New Lab -- It's Finally Up and Running | |
| Lab News! We got a Hot NEW Agilent 1200 HPLC with DAD and a TSQ 7000 tandem sector quadrupole mass spectrometer! Pictures to come! | |
| Click on pictures to enlarge them. | |
I now have a ThermoElectron Corp. LCQ Deca XP! This came from  |
This is Command Central, from where I operate the Dual Parallel Mass Spectrometers |
 |
From this data station, I control the TSQ 700 Tandem Mass Spectrometer, the HP 1050 Liquid Chromatograph with Autosampler, Photodiode Array Detector, Fluorescence Detector, and Evaporative Light Scattering Detector, and I control the LCQ Deca XP ion trap mass spectrometer and the Thermo Separation Products Liquid Chromatograph with Autosampler, Photodiode Array Detector, and Fluorescence Detector, which are pictured at left. |
| Here is the good old TSQ700 Liquid Chromatograph/Mass Spectrometer that I've had for so long! Still running like a Champ! |
