Abstract: A method of measuring concentration of dissolved organic nitrogen in sewage. The method includes: filtering a sewage sample using a filter membrane; measuring the concentrations of total dissolved nitrogen (TDN), ammonia nitrogen (NH4+), and nitric nitrogen (NO3?) in the sewage sample, respectively designated as CTDN(I), CNH4+(I) and CNO3?(I); calculating the ratios of (CNH4+(I)+CNO3?(I))/CTDN(I) and CNO3?(I)/CNH4+(I), and according to the ratios, calculating the concentration of dissolved organic nitrogen (DON) in the sewage sample.

Abstract: In an LC/MS analysis of a sample containing various compounds, additive supply pumps 164A and 164B in a post-column adding unit 16 draw and supply different kinds of additives A and B from containers 163A and 163B, respectively. The additives are mixed into an eluate through T-joints 162 and 161. A preferable combination of the additives is the combination of DMSO which produces the effect of gathering charge states and 2-propanol which produces the effect of promoting atomization or vaporization of droplets. By mixing the two additives into the eluate while mixing them at an appropriate flow-rate ratio according to a previously determined flow-rate program, the ionization efficiency can be nearly optimized for each compound during the process of generating ions by spraying electrically charged droplets of the eluate from an ESI spray 21. Consequently, the detection sensitivity becomes higher than conventional levels.

Abstract: There is provided a method for identifying protein methylation on arginine and lysine residues. The method comprises obtaining a set of peptides; blocking un-methylated arginine and lysine residues and the free N-terminal amine of peptides in the set of peptides, so that un-methylated peptides are neutralized and only methylated peptides are positively charged at neutral or basic pH; isolating the methylated peptides based on charge; and performing mass spectrometry (MS) analysis on the isolated methylated peptides to detect methylated lysine and arginine residues. Methods provided herein can be used for large scale, high throughput profiling of protein methylation in a cell or tissue.

Abstract: Disclosed herein is a low cost and rapid microfluidic based method and test device for quantifying male fertility potential. The device can simultaneously measure three critical semen parameters rapidly, namely live sperm concentration, motile sperm concentration, and sperm motility. The device includes a transparent substrate and a top sheet with two holes therethrough and an intermediate sheet sandwiched between the substrate and the top sheet. The wells formed by holes form a concentration measuring well (C) and a motility well (M) formed by the top sheet with these two holes bonded to the intermediate sheet. A colorimetric agent is located on the top surface of the intermediate sheet at the bottom of each well which changes color when in contact with sperm. In the motility well a porous membrane is located on top of the colorimetric agent and a liquid buffer may be placed on the top surface of the porous membrane.
