Retention time of each peak is marked above the peak and in the tabulated data below the chromatogram details of the retention time, area (as digital units), peak area%, height and height %. You can observe that due to non-ideal shape of peaks percentage area is different from percentage...
Asour ability to analyse water samples has evolvedand our awareness over the potential problems that this could cause has increased, we have begun to pay closer attention to certain chemical compounds in particular. Perhaps the first substance to be named as an emerging cont...
Zeitreihenanalyse monatlicher Mittelwerte von Temperatur, Salzgehalt, Nhrstoffen, Schwebstoffen und Phyto-und Zooplankton in acht Regionen auf dem nordwest... Summary In this study an overview is given of the time series analysis of monthly mean data of physical, chemical and biological parameters...
The researchers analysed the lycopene content in dried and fresh tomatoes, tomato paste and tomato pomace. They used HPLC to analyse the lycopene content after lycopene was extracted from the samples. The use of HPLC to analyse samples is discussed in the article,Pract...
How to read a mass spectrometer? What is the absorbance if you measure the potassium chromate on the preset conditions at 411 nm and 100 \mu M? A. 0.48 B. 0.20 C. 0.96 D. 0.53 Explain the science needed to analyse the environmental issues of Absorption spectra. Describe how a battery ...
After the fracture testing, beam-shaped specimens with all types of tubule orientations, stored in HBSS at 4 °C, were taken to analyse the distribution of the preferential alignment of thec-axis of biological apatite using a microbeam X-ray diffraction system equipped with a transmission opti...
In addition, access to suitable equa- tions could allow one to directly link the network properties to those of a single (average) nanoparticle-junction pair. As we will show, such a link allows the development of new methodologies to analyse junctions. In this work, we develop a simple ...
Until now, little has been known about the composition of spider silk. The breakthrough was thanks to the brown recluse spider, which spins its silk in a unique flat ribbon pattern in comparison to the cylindrical shape adopted by most species. This made the silk easier to analyse under a ...
In addition, five Quality Control (QC) samples were prepared by combining 10 µL of each sample in a 2 mL vial and these pools were injected every seven samples to allow chromatogram alignment during data treatment. In-line UHPLC-UV-HRMS analysis was performed using a Dionex system ...
