摘要:Abstract(#br)Biological samples are complex and often contain many proteins, lipids and other contaminants, which affect the separation and ionization properties of the analytes. Moreover, the concentration of the analytes is very low in comparison with that of the interfering su...

摘要:High-accuracy analyses of polycyclic aromatic hydrocarbons (PAHs) in lipid matrix-based biological samples are highly necessary. We investigated the cleanup performance of the commercially available molecularly imprinted polymers (MIPs) to analyze PAHs in various biological samples...

摘要:Freeze-dried biological samples used for the determination of organotin compounds (OTCs) involve complicated or tedious pretreatment (e.g., freeze-drying) that may result in loss of analyst or contamination. In the present study, a rapid and accurate method for determination ...

摘要:Abstract(#br)The estimation of Pu/ 241 Am ratio in the biological samples is an important input for the assessment of internal dose received by the workers. The radiochemical separation of Pu isotopes and 241 Am in a sample followed by alpha spectrometry is a widely used techniqu...

摘要:Abstract(#br)Solid phase microextraction (SPME) has become a useful tool for in vivo monitoring the behavior of environmental organic pollutants in biological species due to its simplicity, relatively non-invasive, and cost-effective manner. However, the complex matrices in biological samples...

摘要:... however, its inherent enzyme activity would be a potential obstacle in quantifying heme in biological samples. Here, we found that mutation of the catalytically important residue, Asp140, with histidine in the sensor not only diminished the heme degradation activity but also ...

摘要:... The application of these synthetic polymers as sorbents allows not only pre-concentration and cleaning of the sample but also selective extraction of the target analyte, which is important, particularly when the sample is complex and impurities can interfere with quantificati...
