enrichment-system
1.An online enrichment-separation system of C 18 and inductively coupled plasma-mass spectrometry (ICP/MS) with flow injection (C18-FI-ICP/MS) was established for the determination of trace heavy metals in seawater.
2.CHEMISTRY OF MARINE RESOURCES VIII. THE ENRICHMENT BEHAVIOUR FOR POTASSIUM OF THN IN SEAWATER SYSTEM
3.Enrichment and Separation with Sulfhydryl Cotton Spectrophotometry of Trace Cd with 5-Br-PADAP-OP System
4.Some advanced techniques are adopted,such as :screening of raw material under bins, sintered ore mixed with coke nuts for charging,bell less BF top, long life BF shell with soft water closed recycling system and thin refractory lining, hot blast stove with double preheating,“OCP” slag granulation, pulverized coal injection system with high oxygen enrichment, BF gas turbine blower, Bishorf BFG cleaning system, power generation using the extra pressure of BFG, computer automatic control and so on.
5.Based on the summary of observation results of forty uranium deposits located in CIS and Bulgaria which are of different sizes and industrial-genetic types, analysis on available published information concerning oxidation and uranium mineral enrichment in supergenic zone, oxidation zone classification of hydrothermal uranium had been put forward according to the general system of the exogenetic uranium concentration.
6.Main approaches to construct a learning type of editorial department of a journal include: emphasis on self-study to build a concept of life-long study in the department; enrichment of the foundation of knowledge and set-up of a common prospect: establishment of a mechanism of sharing academic achievements and design of a scientific evaluating system of achierements.
7.A concentration, enrichment and clean-up with Oasis HLB cartridge wasdeveloped for beverage sample preparation. Recoveries were ranged from 91.08% to103.19% for all compounds at three different spiked levels. The limit of detections(LOD) of the HPLC system were ranged from 7.0 to 28.0 ng/L of DAD detector and1.0 to 2.4 ng/L of fluoresce detector for material drinking water;
8.Under the optimum conditions (isopropanol/(NH4)2SO4=1.5 mL/4.3 g, acidity of system pH=4.0, concentration of gibbertimes less than 0.064 g/L), a one step extraction percentage(E%) and the enrichment multiple reached to 93.47% and 11.36 respectively.
9.Methods: We isolate cardiac myocytes from ventricles of newborn rats digested bytrypsin and set up methods obtaining mass cardiac myocytes from ES cells based onmass production of EBs using rotary cell culture system (RCCS), induction of EScells into cardiac myocytes using ascorbic and enrichment of cardiac myocytes usingPercoll discontinuous gradient centrifugation.
10.Qinling had undergone four tectonic stages and many times tectonic system changes and resulted in the multi period structure thermal events and ore forming processes since Archeozoic, the ore forming course underwent multicyclic tectonometallogenic evolution also. These created the conditions of the metal elements enrichment and to ore content in large scale.
