Chromatographic separation of amino acids is performed by ion exchange chromatography, followed by detection of ions by conductivity or indirect UV measurement.
The samples for the IONUS are mainly water-based. Analyses according to EPA 300 Part A and Part B are standard.
The autsoampler includes 2x 48 sample vials, which have a capacity of 1.5 mL. For small sample volumes, inlets can be used for the sample vials to ensure proper sample collection.
The system has an alarm system with three different levels. At "yellow" the user is informed about a situation that is not critical, at "orange" a controlled shutdown of the system is performed and at "red" the system is secured against serious damage by emergency shutdown.
The system works with a pre-sequence, the analysis sequence and a post-sequence. When the measurement sequence is completed, the system goes into standby and runs a circulation to keep the system in an equilibrated state to be able to start a new measurement again as quickly as possible.
