«profic 9» ­ professional ic system for trace analysis with inline calibration sample preconcentration and matrix elimination professional ic system for ultratrace analysis of anions or cations in complex matrices «profic 9» with metrohm inline sample preconcentration and matrix elimination allows chromatography unaffected by matrix influences and guarantees that the analytical column has a long working life metrohm inline calibration permits very low concentrations ­ in the ppt range ng/l ­ to be reliably calibrated using a single standard of higher concentration ­ in the ppb range the sample is transferred to the preconcentration column fully automatically and with high precision by the intelligent 800 dosino the anions or cations are retained the matrix can be removed in a rinsing step the clean sample is then transferred to the ic system the 850 professional ic ­ prep 2 is equipped with an additional valve for liquid handling two peristaltic pumps transfer the sample and the rinsing solutions the intelligent magic nettm software controls and monitors the system calibration and calculation of the results as a function of preconcentration volume is also carried out by the magic nettm software even if complex procedures are involved operating the system remains child s play the anion system is additionally equipped with sequential suppression very high sensitivity is achieved by this unique combination of chemical and downstream co2 suppression the flexibility of the carbonate eluent is complemented by the low background conductivity with the preconcentration technique carbonate interference is practically eliminated the 858 professional sample processor ­ pump ­ injector is responsible for sample delivery numerous sample racks for volumes 0.5 500 ml are available typical preconcentration volumes are between 1 and 100 ml applications · ultratrace analysis for anions and cations in nuclear power plants conventional power plants semiconductor industry · trace analysis in organic solvents · quality control of fine chemicals 16
