Composition analysis of falsified chloroquine phosphate samples seized during the COVID-19 pandemic	2020-11-12		.txt	text/plain	3175	170	54	authors: Waffo Tchounga, C.A.; Sacre, P.Y.; Ciza, P.; Ngono, R.; Ziemons, E.; Hubert, Ph.; Marini, R.D. title: Composition analysis of falsified chloroquine phosphate samples seized during the COVID-19 pandemic These suspect samples were first analyzed in a screening phase using field tools such as handheld Raman spectroscopy (TruScan) and then in a confirmation phase using laboratory tools such as hyperspectral Raman imaging and High Performance Liquid Chromatography (HPLC). A previous publication, at the origin of the WHO alert, showed about five falsified tableted chloroquine samples collected in Cameroon and DRC using thin layer chromatography (GPHF Minilab) as a screening method [16] [17] [18] . Raman imaging results showed the presence of chloroquine phosphate in samples F, G and H with correlation coefficients of 0.95, 0.98 and 0.99 respectively. Falsified samples of chloroquine phosphate seized by Cameroon, DRC and Niger during the COVID-19 pandemic were analyzed.	./cache/cord-273495-hruq0hdw.txt	./txt/cord-273495-hruq0hdw.txt
