Katherine Lovejoy
Application Chemist
Katherine Lovejoy is an Application Chemist at the Thermo Fisher Scientific production site for HPLC and for the charged aerosol detector. She has 7 years of experience in that role and enjoys helping others get the best possible CAD results. She earned a PhD in Inorganic Chemistry from the Massachusetts Institute of Technology and has a h-index of 15. Her experience also includes time as a chemist reviewer at the FDA and a scientist at Los Alamos National Laboratory.
DAY 1: February 27th, 2025
SESSION: Aerosol-based detectors (CAD) as a solution to analytical challenges in the evaluation of E&L: troubleshooting and practical answers
◆ Reduction of the uncertainty factor and improved quantification by surrogate standard with CAD.
◆ ELSD/CAD method transfer.
◆ Common, easy-to-eliminate causes of ghost peaks in the blank for existing methods.
◆ Outlook and potential for users who will develop new CAD methods.
DAY 1: March 7th, 2024
SESSION: Implementation of a non-volatility test before quantitating E&L unknowns with a charged aerosol detector
◆ HPLC with 3 orthogonal detectors allows quantitation of unknowns by charged aerosol detectorand identification by easy-to-use low resolution MS
◆ Classification of unknowns as non-volatile or semi-volatile in the CAD reduces the uncertainty factor and improves quantification by surrogate standard.
◆ When using an inverse gradient, improved mixing with an inline capillary mixer after the merge point of the analytical and inverse gradients reduces inter-compound %RSD
