Nice Expert Opinion piece from Paul on Becoming an Expert: Using Raman spectroscopy to analyse vaping ‘e-liquids’.

This article details Paul’s analytical chemistry work in his kitchen and in the lab during the COVID-19 era. This resulted in a great article published in Analyst last year:

• Richardson, P.I.C., Burke, A., Gotts, N. & Goodacre, R. (2023) Quantifying PG:VG ratio and nicotine content in commercially available E-liquids using handheld Raman spectroscopy. Analyst 148, 4002-4011.
