Soybeans were implanted by 30 KeV N + between the dosage of 3×10 15 ～3×10 17 N +·cm -2 ,and the relative activity of the sample’s estase isoenzymes was tested by combining electrophoresis with thin layer scanning.
Benzene-acetone (4:1,V/V)was used as developing agent to soparate amidopyrine and barbitone from the compound amidopyrine injection solution on the silica G plate,and Dual wave thin-layer chromatographic densitometry was used to determine amidopyrine (λ_s = 270nm, λ_R=340nm)and barbitone (λ_x=205nm,λ_R=320nm).
Using benzene as solvent and ethyl acetate-acetone as developer,benzoic and salicylic acids in benzoic and salicylic acids ointment were determinedby dual wavelength thin-layer chromatography densitometry(λ_s=223nm,λ_R=320nm for benzoic acid;and λ_s =295nm,λ_R=360nm for salicylic acid).
Dual waves thin-layer chromatography dcnsitometry (silicagel, ethylacetate-acetone as developing agent) was used to determine benzoic acid (λ_S=223 nm, λ_R=320nm) and salicyclic acid (λ_S=295nm, λ_R=360nm) in benzoic acid compound cream dissolved in the mixed solvent of benzene—methanol.
Method Double wavelength thin -layer chrom atography scanning(TLCS)was performed with benzene -ethyl ac-etate -methanol -isopropyl alcohol-water(6∶3∶1.5∶1.5∶0.3)as developer,detection wavelength at 345nm and reference wavelength at 370nm.
The content of PC in lecithin was determined by dual wavelength thin-layer scanning chromatography with chloroform-methanol-water(65∶25∶4,V∶V∶V)as developing system,λ_S=235nm,λ_R=260nm as measurement and reference wavelength,zigzag scanning with dual wavelength and peak area as quantifying method.
Thin-layer electrochemical studies of the underpotential deposition (UPD) of Bi and Te on cold rolled silver substrate have been performed.
By gel thin-layer scanning analysis, the amount of target protein was determined to be about 20%.
The method of disks in combination with thin-layer chromatography and spectrophotometry was used for a comparative evaluation of the efficiency of different methods of fixing and fermentation of medicinal plants (leaves).
Thin-layer chromatography and a novel rapid color-development assay were used to qualitatively establish the ability of fungi to convert cortexolone to hydrocortisone.
Using thin-layer chromatography of fecal bile acids to study the leopard (Panthera pardus ciscaucasica) population
Quantitative interpretation of the thin bed thickness is essential to thin bed structure interpretation, reservoir description, and lateral reservoir prediction.
Since the reflectance spectrum equation is a continuous function of thin bed thickness and frequency, it is convenient to analyze the effects of a single frequency and bed thickness on the reflectance spectrum.
The reflectance spectrum includes various propagating wave modes and multiples and is better for simulating multi-component thin bed AVO responses than the ray tracing method.
Predicting the distribution of thin bed reservoirs by broad frequency band seismic
Based on forward modeling, we recognized that a thin bed seismic reflection is characterized by changing amplitude with changing frequency (amplitude versus frequency, AVF).
