Ultrasonics. hand - held probe doppler foetal heartbeat detectors. performance requirements and methods of measurement and reporting.
该方法经优化后的条件为：样品经乙腈超声提取，弗罗里硅土柱净化，DAD二极管阵列检测器，经高效液相色谱测定。
The optimized conditions were that the sample was extracted by ultrasonic acetonitrile, cleaned up by Florisil-phase extraction (SPE). HPLC with DAD detector was used for determination.
