Near infrared(NIR)spectroscopy combined with multivariate calibration has been widely used for the quantitative analysis of complex samples in petrochemical,agricultural,pharmaceutical and other field
In this work,a ratiometric fluorescent aptamer sensor was developed to achieve the simple,rapid and label-free detection of Pb2+based on the quantitative fluorescence model(QFM)and dual wavelength mon
This study aims to explore the chemical differences of Acori Tatarinowii Rhizoma(ATR)samples collected from two habitats,Sichuan and Anhui provinces,China.Gas chromatography-mass spectrometry(GC-MS)wa
Infrared spectroscopy(IR)technique combined with multivariate statistical analysis methods is widely used in fundamental and applied chemical research.
In this contribution,an accurate mass spectroscopy quantitative determination platform was developed for target DNA in complex biological samples(i.e.,urine and serum)based on a novel multiplicative e
Data smoothing is of great importance for chemical signal pretreatment.Although the Savitzky-Golay(SG)algorithm has become an almost universal method to smooth any kind of signal,there may be room to
