Page 3 of 838 Advanced IC Sample Processor by Metrohm AG

advanced ic dialysis sample processor 2.838.0110 the advanced ic dialysis sample processor easily masters the unique inline dialysis sample preparation procedure patented by metrohm the dialysis cell is mounted vertically in the 820 advanced ic separation center a second valve is no longer required if another peristaltic pump 2.833.0010 is added to the setup dialysis has significantly expanded the application range of ion chromatography the diffusion-driven ion exchange through the semi-permeable and hydrophilic dialysis membrane made of cellulose acetate allows to analyze without manual sample preparation and with high precision even very difficult samples such as cutting oil emulsions blood urine milk or beer advanced ic dilution sample processor 2.838.0120 highly concentrated solutions often have to be diluted the classical manual procedure is to dilute the sample before sample injection and above all before the sample is placed on the sample changer metrohm inline sample dilution simplifies this step the concentrated sample is placed into a vessel all the rest is taken care of by the 838 advanced ic dilution sample processor fully automatically and with high precision different samples can be allocated different dilution factors that are automatically taken into account for the inline sample dilution the 838 advanced ic dilution sample processor is supplemented with a dosino and an external sample station with stirrer where the dilution takes place the built-in six-way injection valve is used for the different dilution and rinsing steps the dosino offers maximum flexibility together with high precision which makes it possible to perform dilutions up to a factor of 1:500 the dual-channel peristaltic pump whose rotation rate and flow direction can be varied is used for the efficient rinsing of the sample station between samples carryover from one sample to the next is less than 0.5 applications · anions in surface water samples after automatic inline ultrafiltration · anions and cations in industrial waste water samples by means of inline dialysis · analysis of carbohydrates with the 817 bioscan pad pulsed amperometric detector · anions in cutting oil emulsions after inline dialysis · cations in brine after automatic dilution · anions in blood and urine after inline dialysis · organic anions in champagne after inline ultrafiltration · anions in concentrated sodium hydroxide solution by means of inline neutralization · trace analysis of anions and cations in ultrapure water samples after inline sample preconcentration of large volumes · rapid determination of phosphoric acid in cola drinks · etc geniessen sie ihr wochenende während der 838 für sie arbeitet die automation in der ionenchromatographie hilft arbeitszeit und selbst freizeit optimal zu nutzen es gibt keinen grund mehr zeit für routinetätigkeiten wie manuelle probenaufgabe oder probenvorbereitung zu verschwenden der wechsler übernimmt alle diese funktionen bis zu 148 proben finden auf dem probenteller des advanced ic sample processor 838 standardmässig platz einmal angenommen die analyse einer probe benötige 20 minuten so kann der probenwechsler diese 148 proben übers wochenende selbstständig erledigen «human touch» oder hohe präzision manuelle probenaufgabe führt in den meisten fällen zu grösseren standardabweichungen der messergebnisse mit metrohm-probenwechslern ausgestattete systeme liefern hervorragende reproduzierbarkeiten wenn es darauf ankommt sehr genaue ergebnisse zu erzielen und alle abläufe automatisiert und dokumentiert durchzuführen ist der «high end» advanced ic sample processor 838 das gerät der wahl lateral view of 838 advanced ic sample processor technical specifications exchangeable sample racks automatic rack identification sample volume standard sample rack number of samples standard sample rack maximum number of samples definable positions swing head connection external position rs 232c connection remote connection msb connections connection for 802/741 stirrers connections for 801/804/802 stirrers keypad with built-in intelligence software-compatible ic net number of workstations integral dual-channel peristaltic pump ­ selectable rotational direction ­ variable velocity external pump connections membrane pumps integral six-way injection valve sequences can be freely programmed via keypad individual steps per sequence 3 sequences per method method storage capacity of the instrument method storage capacity of the pc splash protection 800 dosino 801 magnetic stirrer yes yes 0.5 250 ml 12 148 999 1 1 yes yes 3 1 3 yes yes 1 yes yes yes 2 yes yes 99 approx 100 unlimited yes optional optional ion chromatography
