Controlled exposure. Measurable response.
Controlled VOC dosing
An integrated benchtop platform for controlled gas and VOC sensor testing—from concentration calculation and heated exposure to real-time electrical characterization and sensor recovery.
Heated glass chamber
Real-time measurement
Recovery cycling
Complete the sensing experiment
without assembling every subsystem.
One integrated platform
Schnaiffer combines the essential hardware and workflow required for repeatable sensor exposure, measurement and recovery—allowing researchers to concentrate on sensing materials, device performance and experimental data.
04 / RECOVER
Flow and Recovery
Restore the baseline and repeat exposure-recovery cyclesa
01 / CONTROL
Defined VOC dosing
Calculate and introduce the required liquid analyte quantity
02 / EXPOSE
Heated test chamber
Mount and expose the sensor under controlled temperature
03 / MEASURE
Electrical Characterization
Monitor resistance, capacitance, impedance, voltage or current
Measure the sensor inside its actual exposure environment.
The sensing device is positioned on an electrically insulating ceramic stage inside the glass chamber. Electrical connections are routed outside for continuous measurement during VOC exposure.
