| liquid handling with the 800 dosino the 800 dosino is the only electronic buret with 10 000 precise volume steps when equipped with a 10-ml glass buret volume increments of only 1 l can be added the 800 dosino is an integral part of the liquid handling setup in metrohm ic systems for use in power plants in cooperation with the 838 advanced sample processor the dosino carries out various tasks related to «misp» metrohm inline sample preparation the system is completely controlled by the metrodata ic net software via the «msb» metrohm serial bus inline sample preconcentration the 800 dosino transfers ... | |
| liquid handling with the 838 advanced sample processor the 838 advanced sample processor prepares samples for analysis more than 30 different sample racks are available and are automatically recognized by the sample changer sample volumes from 0.5 to 500 ml are safely handled up to 148 samples of up to 11 ml can be accommodated on the standard sample rack in ultratrace analysis the sample vessels play a significant role because as the volume of the sample vessel increases the risk of contamination and adsorption by the vessel walls decreases for example 125-ml nalgene® bottles are recommended these ... | |
| applications determination of cations in the secondary circuit of nuclear power plants the «mic-4 advanced»-system is used for this application the standard system has been extended by the 838 sample processor with 800 dosino i trap column and the transfer tubing two «misp» techniques are used · inline calibration · inline sample preconcentration calibration the calibration values are selected so that the whole of the expected concentration range is covered the linearity of the inline calibration is excellent the correlation coefficients for all cations are >0.999 cations calibration levels of ... | |
