BME680 calibration tests
Description
This dataset contains data for 8 different concentrations of alpha-pinene: 1 ppb, 10 ppb, 25 ppb, 50 ppb, 100 ppb, 200 ppb, 500 ppb, and 1000 ppb. Each concentration was tested in triplicate using three different sensors: TCA0, TCA1, and TCA3. Each concentration run includes three repetitions for each sensor.

GC validation
Description
This dataset contains data for three concentrations: 30 ppb, 50 ppb, and 100 ppb. Each concentration has two files: one for internal standard results and another for tested alpha-pinene. Each concentration was tested in triplicate. The processed data is compiled in an Excel workbook titled 'Peaks areas'.
