Response surfaces and contour plots of the contents of total lignans, chlorogenic acid, arctiin, and arctigenin were obtained through ultraviolet and visible (UV-Vis) monitoring and high performance liquid chromatography (HPLC).
We compared the measured zeta potential and UV-vis spectra (monitored in the range of 200 to 800 nm) of the Au-DNA to the DNA solution and found that the features of DNA (the zeta potential is −36.0 and a shoulder UV peak at 260 nm [25]) remain unchanged before and after the reaction (shown in Table 2 and Figure 5).
Applicability of UV-VIS spectroscopy for monitoring surface reactions of hydrocarbons in acidic zeolites has been demonstrated by the examples propene/HNaY, cyclohexene/HZSM-5 and neopentane/HNaM.
RNA quantity and purity were assessed by Nano-Drop (ND-1000 UV-Vis spectrophotometer; NanoDrop Technologies) monitoring the absorbance at 260 nm and the 260/280 nm and 260/230 nm ratios (Both ratios were about 2.0).
The progress of Ag NPs formation was monitored by recording Vis spectra every minute using the Gary 60 UV-Vis spectrophotometer (Agilent Technology, Malaysia).
Dirt's life is emblematic of the distinct and interrelated issues of drug addiction and mental illness, as well as public health bureaucracies' inability to monitor these issues vis-à-vis black folks.
UV-vis absorbance spectra were monitored by a UV-vis spectrophotometer TU-18100, Purkinje General Co., Ltd, Beijing, China).
This paper demonstrates the feasibility of using a fiber-optic equipped visible-near-infra-red (Vis-NIR) spectrometer to monitor both colour and composition in an extruder during the extrusion of yellow corn flour.
The formation of the AgNPs was monitored by UV-vis spectroscopy using Shimadzu (Model No-UV 1800) double beam UV-vis spectrophotometer [ 3].
The optical properties of silver particles were monitored by UV-vis spectroscopy.
The products and substrates of this reaction were easily monitored by UV-Vis spectroscopy.
