Linear dependence of derivative values on analyte concentration is maintained in a range 3.12 microg x mL(-1) - 44.80 microg x mL(-1). Detection and determination limits are in the range 0.51 - 3.23 microg x mL(-1) and 1.27 microg x mL(-1) - 9.80 microg x mL(-1), respectively. Determination results of drug constituents are very accurate. Recovery percentage is in a range 95.50% - 103.60%. | | Language | eng | | Pub Type(s) | Journal Article
