Determination of Atropine Sulfate in Human Urines by Capillary Electrophoresis Using Chemical Modified Electrode as Electrochemiluminescence Sensor

Table 1

The determination of atropine sulfate in patient urines (𝑛=5).

Sample	Found (mg·mL^−1)	R.S.D. (%) for peak area	Added (mg·mL^−1)	Recovered (mg·mL^−1)	Recovery (%)
1	0.112	1.52	0.100	0.0986	98.6
2	0.0782	2.19	0.100	0.0909	90.9

Conditions were the same as Table 1. Sample 1 was from the patient who was operated for the polyp excision after ca. 3 h when atropine sulfate was injected; sample 2 was from the patient who was operated for uremia after ca. 8 h when atropine sulfate was injected.
