There is, apparently, no reason any more to waste time on routine work such as manual sample injection or manual sample preparation, as this sample processor takes over all these tasks
The 838 IC sample processor represents the latest generation of high-performance sample processors for ion chromatography.
Metrohm sdays it sets new standards regarding flexibility, sample preparation, liquid handling and sample throughput.
Sample volumes ranging from 500ul to 250ml can be processed, 999 sample positions can be accessed; with up to three Dosinos, two membrane pumps, and a bidirectional peristaltic pump the possibilities offered for liquid handling are virtually unlimited, it adds.
More than thirty years of experience in sample changer design - the first Metrohm sample changer was marketed in 1973 - guarantee the usefulness of its products, it says.
With the 838, Metrohm presents an instrument that is described as extremely user-friendly and allows substantial savings.
Automation in ion chromatography helps to optimally organise working hours.
There is no reason any more to waste time for routine work such as manual sample injection or manual sample preparation, says the company; the sample processor takes over all these tasks.
The 838 IC sample processor's sample rack accommodates up to 148 samples.
If the analysis time for one sample is assumed to be 20 minutes, the sample processor will take care of these 148 samples over the weekend.
Human touch or high precision?.
In most cases, manual sample injection means increased standard deviation of the results.
Systems equipped with Metrohm sample processors yield excellent reproducibilities, it says.
If the aim is to obtain highly accurate results and to automate and document all the sequences, the 838 is the instrument of choice, it says.
The 838 advanced IC sample processor comes in five versions.
The application determines which sample processor is the right one.
838 Advanced IC Sample Processor (2.838.0010); Advanced IC Injection Sample Processor (2.838.0020); Advanced IC Filtration Sample Processor (2.838.0210); Advanced IC Dialysis Sample Processor (2.838.0110); Advanced IC Dilution Sample Processor (2.838.0120).
Typical applications include 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 neutralisation, trace analysis of anions and cations in ultrapure water samples after inline sample preconcentration of large volumes, and rapid determination of phosphoric acid in cola drinks.
