| Digestions of 24 round cells with pre-programmed and user-defined programs |
| In total 24 round cells (16 mm) in two seperate heating blocks using the same program |
| • 8 stored programs for easy and fast operation including COD fast digestion |
| • 8 user-defined programs from room temperature/25-170°C with high temperature digestion |
| • AQA/IQC with optional external temperature sensor for documentation |
| Programs for standard parameters COD including fast digestion (148°C, 20 min.), total nitrogen, total phosphorus, TOC and heavy metals of galvanizing with automatic heating and switch-off quick. User defined programs can be easily entered and stored from room temperature respectively 25-170°C to perform special digestions and thus allow high temperature digestion. |
| The very same program can be run for all vials at the same time; to perform two parallel digestion programs, the CR 4200 is the suitable choice. For the analytical quality assurance (AQA), the external temperature sensor TFK CR can be connected to the PC/printer instead of a round cell. |
| Programs for standard parameters |
| •1: 148 °C for 120 minutes |
| •2: 120 °C for 30 minutes |
| •3: 120 °C for 60 minutes |
| •4: 120 °C for 120 minutes |
| •5: 100 °C for 60 minutes |
| •6: 148 °C for 20 minutes |
| •7: 150 °C for 120 minutes |
| •8: 100 °C for 30 minutes |
