Abstract
This invention relates to a device for detecting fungal contamination in an interior environment, including: a concentration module (MC); a separation module (MS) including a chromatographic microcolumn; and a detection module (MD), characterized in that it includes at least one first solenoid valve (E3) upstream of the detection module (MD) enabling either to direct a flow containing target molecules toward the detection module (MD), or to direct a flow filtered by a first means for filtering (Tx1), enabling the detection module (MD) to be cleaned when the flow does not contain the target molecules. The invention also relates to a control interface of the device.
Claims22
Device for detecting fungal contamination in an interior environment, including:
- a preconcentration module (MC);
- a separation module (MS) including a chromatographic microcolumn downstream of the preconcentration module (MC);
- and
- a detection module (MD) including a sensor matrix downstream of the separation module (MS),
- flow generating means, preferably at least one pump (P),
- characterized in that it includes at least one first solenoid valve (E3) upstream of the detection module (MD) enabling either to direct a flow containing target molecules toward the detection module (MD), or to direct a flow filtered by a first means for filtering (Tx1), enabling the detection module (MD) to be cleaned when the flow does not contain the target molecules.
Process for detecting fungal contamination in an interior environment using a detection device including:
- a preconcentration module;
- a separation module including a chromatographic microcolumn downstream of the preconcentration module;
- and
- a detection module including a sensor array downstream of the separation module,
- flow generating means, preferably at least one pump,
- the process including steps of:
- concentration (20), in which target molecules are retained in the preconcentration module, preferably for a concentration time;
- sensor cleaning (30), in which a filtered flow passes through at least one among the preconcentration module, the separation module or the detection module,
- analysis (40), in which the target molecules pass into the detection module, preferably for an analysis time.
