Studies on injector pump-ultrasonic nebulizer feeding sample system for MPT-AES
例句来源
The feeding-sample system used by microwave plasma torch atomic emission spectroscopy (MPT-AES) is the pneumatic nebulization system; its efficiency, however, is not good.

Well-defined core-shell structure and narrow particle size distribution could be achieved under starved conditions of monomer feeding.
Medium chain fatty acids, C8-C11, were obtained from the byproducts of petroleum and then esterified with natural or synthetic glyceroi to form four kinds of synthetic oil. Different experimental diets were prepared by using these synthetic oils as dietary sources of fat. These diets, together with a low fat basal diet and a soybean oil diet, were fed respectively to 7 groups of weanling rats. Body weights and serum cholesterol were measured during 12 weeks of feeding. At the end of this period, the a...
Diets with 15% fat, containing 78, 68, 48, 38% saturated fatty acids and stock diet were fed to five groups of rats. After four weeks of feeding, radiolabelled 3H cholesterol and 14C triglyecride were gavaged and lymph was collected 0-8 hour and 8-24 hour after diets, all under 37℃. The lymphs was supercentrifuged to chylomicrons, VLDL,LDL and HDL. The fat contents in plasma and liver, in lymph lipoproteins, their absorption rates, fatty acid composition and apoprotein composition were measured. Using...
Soy flour and peanut flour have long been used as protein supplement in infant and child feeding. In this study the nutritive value of different heat processed soy flour and peanut protein concentrate were measured by means of chemical and biological methods. The samples tested included: (1) Soy flour, wet heat treated-soybean was cleaned, soaked, steamed, dried and ground to powder. Such a process is time consuming, and therefore inconvenient in large scale production. (2) Soy flour, infra-red expose...
