LC-MS-Based Metabolic Fingerprinting of Aqueous Humor

Table 2

The number of metabolic features detected with different slopes of the gradient.

Method	Number of metabolic features detected			The % of reproducibly measured metabolic features
	Total	CV < 30%	CV < 20%	CV < 30%	CV < 20%
15 min	1445	1346	1283	93.1%	88.8%
17.5 min	1311	1226	1188	93.5%	90.6%
20 min	1407	1319	1300	93.7%	92.4%

The numbers of metabolic features detected do not include features present in the blank extraction. Presented results include data from both ion modes.
