The 881 Compact IC pro – Anion is an intelligent ion chromatograph of compact design with column oven for the determination of anions or polar substances with chemical suppression. It can be operated with various types of detection. The 881 Compact IC pro line of instruments is distinguished by:
- the intelligence of its components, which are able to monitor and optimize all functions and to provide documentation according to FDA requirements.
- its compact style of construction.
- its transparency. All components are easily accessible and arranged in a clear manner.
- its safety. Chemicals and electronics are separated and a leak sensor is integrated in the wet end.
- its environmental compatibility.
- its low noise emission.
The instrument contains the following components:
Eluent degasser
The eluent degasser removes gas bubbles and dissolved gases from the eluent. For degassing, the eluent flows into a vacuum chamber through a special fluoropolymer capillary.
High pressure pump
The intelligent and low pulsation high pressure pump pumps the eluent through the system. It is equipped with a chip on which its technical specifications and “life history” (operating hours, service data, … ) are saved.
Inline filter
Inline filters protect the separation column securely against possible contamination from the eluent. Inline filters can however also just as well be used for the purpose of protecting other sensitive components against contaminations in the solutions used. The filter platelets with a pore size of 2 μm can be replaced quickly and easily. They remove particles like e. g. bacteria and algae from the solutions.
Pulsation absorber
The pulsation absorber protects the separation column from damage caused by pressure fluctuations when switching the injection valve, and reduces interfering pulsations during highly sensitive measurements.
Injection valve
The injection valve connects the eluent and sample path through rapid and precise valve switchover. A precisely measured amount of sample solution is injected and rinsed with eluent onto the separation column.
Column heater
The perfect isolation of the column chamber ensures thermally stable conditions for the separation column. The temperature of the column heater can be set in the software.
Peristaltic pump
The Peristaltic pump is used for pumping sample and auxiliary solutions. It can rotate in both directions.
Metrohm Suppressor Module (MSM)
The MSM is used for chemical suppression in anion analysis with conductivity detection or UV detection. It is pressure-stable, robust and resistant to solvents.
Separation column
The intelligent separation column is the heart of the ion chromatographic analysis. It separates the different components corresponding to their interactions with the column. Metrohm separation columns are equipped with a chip on which their technical specifications and their history (first use / setting up, operating hours, injections, …) are saved.
The 858 Professional Sample Processor processes samples from 500 µL to 500 mL. The sample transfer takes place either by means of a peristaltic pump on the 850 Professional IC system or with an 800 Dosino.
