mass spectrum analysis การใช้

• The highest concentration of mercury was found in the antennal glands by mass spectrum analysis
• Moreover , the mass spectrum analysis of the hydrolyzed water soluble products of phb powder after treatment of enzyme was performed and the main product was identified to be dimers
• A lot of mercury granules were found primarily in antennal gland by transmission electron microscope and mass spectrum analysis . mercury granules were found in the lysosome of the cell of antennal gland , and were transited to lumen by apocrine secretion
• The distribution and accumulation of three kinds of heavy metals including lead , copper and mercury in tissues and cells of several organs , and their effects on activity of digestive enzymes and alkaline phosphatase of macrobrachium nipponense were studied with light microscopy , transmission electron microscopy , cytochemical method , atom absorption spectrum , mass spectrum analysis and enzyme analytical method
