Metrohm has brought out the Profic 3 (Professional 850 IC) system.
Profic 3 features inline stopped flow dialysis, a fully automatic sample-preparation technique for heavily loaded sample matrices that would normally disturb the baseline and prove detrimental to the lifetime of the separation column.
This column is the most expensive consumable accessory in Metrohm Intelligent IC instruments.
Automation enhances the sample throughput and reduces handling errors; both of these in turn help reduce analysis costs.
Dialysis effectively removes particles and colloids from various samples; for example it can effectively determine emulsions, fat-containing samples, bodily fluids and strongly polluted wastewaters without damage to the column.
The driving force behind dialysis is diffusion, as only ions can pass through the dialysis membrane, not particles.
This extends the life of the membrane and, for example, prevents oil droplets from reaching the column through the membrane.
The dialysis cell is mounted directly inside the 850 Professional IC and the two peristaltic pumps that control the stopped flow dialysis are automatically controlled by the Intelligent Magic Net software.
Magic Net is an integral part of Intelligent IC and allows logical decisions to be performed - for example automatic inline sample dilution - and monitors all the intelligent system components (Ipump, Icolumn, Idetector and intelligent dosing units), notifying the user, for example, when maintenance or service is required.
The intelligent hardware is equipped with a memory chip that stores device-specific data.
When the method is started, the parameters are checked, ensuring accurate and reliable results time after time.
Metrohm inline dialysis has low running costs, as the cell uses standard 47mm diameter membranes and the whole procedure is automated once the sample is introduced onto the carousel of the sample processor (autosampler).
