ATR fully automatic solid-phase extraction concentration systemThe core of the operation process is "sample preparation → automatic extraction → concentration and purification → collection for later use", with concise and standardized steps.
1、 Preliminary preparation
Confirm the status of the instrument, check the sealing of the pipeline, the vacuum degree of the concentration module, and ensure that the heating device is functioning properly.
Preparation of samples: Complete sample homogenization, centrifugation, filtration and other pretreatment according to testing requirements, adjust pH value and ionic strength.
Install a compatible solid-phase extraction column, prepare eluent, rinse solution and other reagents, and connect them to the corresponding pipelines.
2、 Instrument parameter settings
Input sample information: basic parameters such as sample volume and target object type.
Set extraction parameters: sample flow rate, rinsing frequency, eluent dosage, and flow rate.
Configure concentration parameters: Set the concentration temperature, vacuum degree, and collection volume according to the solvent type.
3、 Automatic operation phase
Sample loading: The instrument automatically pumps the preprocessed sample into the solid-phase extraction column, and the target substance is adsorbed onto the packing material.
Rinsing: Pump in the rinsing solution to wash away residual matrix impurities in the column and reduce interference.
Elution: The adsorbed target substance is desorbed from the column and exported through the eluent.
Concentration: The eluent enters the concentration module and is heated and depressurized to remove the solvent, then concentrated to the set volume.
4、 Subsequent processing
After concentration is completed, the instrument automatically collects the concentrated solution into the sample bottle.
Take out the sample bottle, seal it, and use it for subsequent chromatographic analysis and other detection processes.
Run the instrument automatic cleaning program to clean the pipelines and modules, avoiding residual contamination.
