CHRONECT Symbiosis | Plus

Flexible online SPE-UHPLC system for routine and research

The CHRONECT Symbiosis Plus version reduces sample preparation time and enables LC peak focusing with mixed-mode SPE cassettes.

This configuration contains two SPE clamps using 250 bar clamps and SPE cartridges. With the second clamp, the system is suitable for rapid SPE method development or 2D/orthogonal SPE using two different types of SPE cartridges in series. Simple breakthrough testing reduces method development time. The system allows selection of different SPE methods for optimal purification of sample extracts. Peak focusing, as a built-in standard mode, and selectable mixed- mode SPE cartridges and methods can also be used to extract your samples. With two SPE clamps, you can purify your sample on second SPE cartridge while simultaneously eluting your analytes into LC-MS from the previously prepared first SPE cartridge. The total sample run time, including SPE sample preparation, is then determined by the LC-MS analysis time. Also with this system, you can perform direct UHPLC injection without reconfiguring your system hardware.

CHRONECT Symbiosis is controlled by CHRONOS Symbiosis 

CHRONOS organizes the connection to the LC-MS. All CHRONECT Symbiosis systems are able to process multiple batches/assays quickly and reliably with maximum analytical performance without supervision.

Special features of the
CHRONECT Symbiosis solutions

SPE cartridges

The online SPE cartridge for Symbiosis ACE systems has been specially developed for online elution to the HPLC column. The dimensions are optimized to combine high extraction capacity with small elution volumes. Standard are 10 mm length and 2 mm inner diameter. Of course, these cartridges resist the typical HPLC system pressures (max. 300 bar). All cartridges are also available in 10 x 1 mm; then the maximum pressure is 1,000 bar. These versions are manufactured with PEEK instead of PVDF. The materials for the sorbents are the same for both cartridge types.


Each cartridge is marked with a code indicating the brand, type and batch of SPE sorbent. In addition, 96 car-tridges each are provided in a rack that is inserted directly into the CHRONECT Symbiosis system for process-ing: No cartridge needs to be touched! Each tray contains an RFID chip that transmits cartridge type, lot number, production number (unique) and expiry date to Symbiosis. This information is displayed on the PC screen and is attached to the analysis report. After processing, the Symbiosis system transmits data about used/unused positions to the RFID chip. Racks can thus be stored safely without the need to label or remove used cartridges.


Method development

The systems are delivered with standard methods. These can be modified and adapted to the respective ap-plications at any time. When developing your own methods, many publications, application notes or scientific posters will help you.

Cartridge Packaging Program

A cartridge packaging program allows you to use your specific sorbents. In a first phase, it is possible to produce a smaller test batch with customer-supplied materials. This requires 10 g of sorbents for 25 cartridges. A safety data sheet must be available for the materials provided. If the results meet the expectations, a batch with at least 10 racks per order can be produced.
