Table 1

System suitability parameters.

Parameter	Almotriptan	Clidinium bromide	Chlordiazepoxide
Theoretical plates (𝑁)	1711	4174	6598
Resolution factor^a (𝑅𝑠)	—	2.59	5.19
Tailing factor (𝑇)	1.03	1.43	1.16
Capacity factor (𝑘)	2.19	2.90	4.20
% RSD for seven injections	0.31	0.28	0.27

a The resolution factor is calculated between each peak and its nearest preceding neighbor.
