which demands preliminary sample preparation of urine.
Triamterene in urine can be determined in presence of
studied diuretics by emission intensity with high sen-
sitivity. Simple method of amiloride determination in
human urine was proposed. It does not include long sam-
ple preparation but provides high specifity of analysis
with sufficient sensitivity. The reduction of time of ana-
lysis due to avoiding sample preparation merits the tech-
niques proposed.
