LCMS combines the separation capabilities of liquid chromatography (LC) with the detection capabilities of mass spectrometry (MS). After separation by LC, compounds are ionized and then introduced into the mass spectrometer, which identifies and quantifies them based on their mass-to-charge ratio. ...
高效液相色谱法(HPLC)已应用于定性和定量分析,可作为鉴定和评价复杂性质中草药质量的一种方法。在定量方面,高效液相色谱和液相色谱质谱(LC-MS)联用分析已被证明是一种快速有效的分析技术。鲜有对红枣提取物进行定性和定量分析的色谱方法。...
(LC/MS and LC/MS/MS) and is routinely used for quantitative analysis in biological samples such as blood, urine and other body fluids. HPLC consists of using a liquid mobile phase to pass under high pressure a mixture of analytes extracted from the sample through a column containing the ...

(DMPK) is the step where the seeker composites for medicine are tested for their metabolism and pharmacokinetics. The studies involve the use of LC-MS or LC-MS/MS. The thing in the discovery stage of medicine development is to discover a new, safe and active chemical reality (NCE) that ...
The intra and interday assay precision were less than 9.2% and 12.0% for LC-MS and HPLC assay. The pharmacokinetic parameters were estimated using noncompartmental pharmacokinetic model with WinNonlin. Busulfan AUClast showed an average difference of 0.7% between the two methods. The LC-MS ...
