The PFPD has advantages over the other two phosphorus sensing GC detectors: 1) the Thermionic Specific Detector (TSD), a nitrogen-phosphorus detector, and 2) the Flame Photometric Detector (FPD). Comparisons are made between these detectors. Finally, high speed data acquisition firmware and software that allows one to easily set up the PFPD and review the pulsed emission data emanating from eac...
It has been pointed out that SARS-CoV-2, the cause of COVID-19, can droplet or nucleus infection by aerosol particles. Therefore, there is a growing need for method to investigate behavior Currently, it impossible visualize particles and measure their concentration simultaneously. In this study, measuring visualizing flame photometry was developed. method, consisting sodium chloride solution us...
Various ion-selective electrodes based on valinomycin (Table 1) have been widely used for determination of the K + concentration in whole blood, blood plasma, and undiluted and diluted blood serum, as well as in diluted urine [for a review see (1)]. Plasticized poly(vinylchloride) membranes (columns 2 and 3 in Table 1) have been of special interest. Although these electrodes, especially the one...
