Advances in FTIR and UV-Vis: No Need for Cells in Liquid Sample... This webcast will highlight the benefit of advanced sampling technologies in achieving fast, easy, and reliable measurements of liquid samples in comparison with the traditional liquid cells used for FTIR and UV-Vis measurements...
For gas samples and liquid samples, it can be equipped with a transmission box (see picture above). 2. Samples Thermo Nicolet FTIR spectrometers can measure gaseous, liquid and solid samples. The 6700 FTIR standard configuration uses the Smart-iTR setup. The Smart iTR is an ultra-high-...
Biosynthesis of metal clusters for the nitrogenase component proteins NifH and NifDK involves electron donation events. Yet, electron donors specific to the biosynthetic pathways of the [ 4Fe-4S] cluster of NifH, or the P-cluster and the FeMo-co of NifDK, have not been identified. Here we ...
of the water bands, but depressurizing the sample chamber to a vacuum causes liquid samples to vaporize, preventing ATR sample measurements of the sample. The liquid triple-reflection ATR crystal plate for the THz (far-infrared) region that can be mounted on the ATR-500/Mi, used for these...

To perform long-path absorbance measurements for liquid samples, a luminescence detector cell must act as an optical fiber or waveguide. Otherwise, excessive noise results. And if the cell is to function as a liquid core waveguide, it must be made of material with a lower refractive index ...
Bruker Alpha-P ATR FTIR 标准操作程序 (Diamond-ATR)说明书 Last Updated: October 2020 Version: 5 Bruker Alpha-P ATR FTIR Standard Operating Procedure (Diamond-ATR)1.Introduction 1.1.Purpose To outline the procedure for the IR analysis of a course-provided or course-produced sample with the ...
The diffusion coefficient values have been calculated for different samples and interesting variations of the diffusion coefficient as a function of sulphonation level, solvent and film thickness have been analysed in detail. 展开 关键词: Physical chemistry Chemistry, Physical and theoretical Plastics ...
1.1Click on the OMNIC icon to open the software.1.2Using the icon bar, open the “Experiment Setup” Array menu by clicking on . Check that a signal is being measured under the “Diagnostic” tab.You should see a peak centered in the left window with a max value above 6.5.1.3If...
For liquid and paste samples we will typically use a HATR (Horizontal Attenuated Total Reflectance) multi bounce technique which will involve placing the sample on a crystal plate or trough in the horizontal position such that gravity acts to make the intimate contact with the cell. Different crys...
