The aim was to establish a first, basin-wide estimate of microlitter contamination across compartments, setting a baseline for further monitoring. The survey showed that the abundance of microlitter in riverine sediment (0 – 4000 particles.kg-1 dry weight (dw)) and riverine water (1.00 ± ...

Nowadays, the entry of toxic substances through food and drinking water generates free radicals which induce several diseases in the human body. It is due to the free radicals of reactive oxygen species attack on fatty acids, DNA, proteins, lipids, and initiate a rapid destructive chain reaction...
So, one of the main targets of greening chromatography is a solvent-reducing approach, where the most common mobile phases containing methanol are replaced by less harmful and more ecofriendly alternatives, such as water, ethanol and isopropanol29. The aim of this newly developed method is ...
Sutariya, Wehrung, and Geldenhuys (2012) developed a method for quantification of GSH in nanoparticle solutions using direct UV detection at 215 nm. The mobile phase was acetonitrile: water (pH 7.0) (50:50, vol/vol) at a flow rate of 1 ml/min. The method was simple and did not ...

Qualitative Reaction Lab Observing a Single ChemicalReactionQualitativevs. Quantitative Observations Abstract: The purpose of this experiment is to help you sharpen your observational skills. The aluminum foil was found to rust in the water containing the dissolved Copper Chloride (CuCl₂) crystals. Th...
However, when taking a closer look at these standards, many describe similar methods and most of them are specific for O2 and water vapour permeation testing. In Table 1, Table 2, Table 3 the international used standards of the International Organization for Standardization (ISO) and the ...
in HIV-TB co-infection. In order to study possible changes in plasma levels of these hormones, we developed an approach based on high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). To our knowledge, this represents the first report of their simultaneous measurement in ...
