32050063-4	2020	The best results were obtained with citrate-buffered version QuEChERS and a cleanup step, with 150 mg of MgSO4, 50 mg of primary secondary amine (PSA), 50 mg of C18, and 5 mg of carbon.	Citric Acid	36-43	Bardet-Biedl syndrome 9	Homo sapiens	161-164	
34537657-2	2021	C18-CDs are synthesized by simple one-step solvothermal method using octadecylamine and citric acid as carbon sources, and C18-CDs with proper polarity are collected through column chromatography purification.	Citric Acid	88-99	Bardet-Biedl syndrome 9	Homo sapiens	0-3	
30224277-6	2018	By evaluating the total ion chromatograms (TIC) on GC-Orbitrap-MS of different extracts using various sorbents, QuEChERS citrate using EMR-Lipid sorbent resulted in the cleanest extract among Z-Sep, Primary secondary amine (PSA), Oasis  Prime HLB, and Supelclean  Ultra cartridges that consist of a top bed of PSA, C18 and Grashsphere  2031 and a bottom bed of Z-Sep. Later, the analyses were performed on a GC-QQQ-MS/MS, applying a 15 min runtime method covering 205 compounds.	Citric Acid	121-128	Bardet-Biedl syndrome 9	Homo sapiens	315-318
