Data sections

The Bruker Invenio S is a benchtop Fourier Transform Infrared (FTIR) spectrometer operating in the mid-infrared (MIR) range. It covers approximately 2501–16686 nm (4000–600 cm⁻¹) at ~0.9 nm resolution, producing 2383-element spectral arrays stored in ascending wavelength order. FTIR requires milled samples (ds2m preparation) for optimal performance.

Prerequisites

The bruker invenio s ftir provision and its provision_serial_nr must exist from Load utility data.

Notebook cell

In load_ai4sh_spectral_data.ipynb, the Manage FTIR spectrometer cell runs:

job_file = 'import_data/FTIR_spectra/job_ftir_spectrometer.json'

structured_process_D, scheme_params_D = Initiate_process(notebook_path, scheme_file, job_file)

if structured_process_D is not None:
    Run_process(structured_process_D, scheme_params_D)

Job file

Path: ./ai4sh/import_data/FTIR_spectra/job_ftir_spectrometer.json

{
  "process": {
    "job_folder": "import_data/FTIR_spectra/spectrometer",
    "process_sub_folder": "process",
    "pilot_file": "xspatula_add_spectrometer_pilot.txt"
  }
}

Process file

Path: ./ai4sh/import_data/FTIR_spectra/spectrometer/process/bruker-invenio-s-ftir_spectrometer.json

{
  "process": [
    {
      "process": "manage_spectrometer",
      "parameters": {
        "provision_id__provision_name": "bruker invenio s ftir",
        "wavelength_unit_id__wavelength_unit_name": "um",
        "wavelength_array": [2501.1, 2502.0, 2502.9, 2503.8, "...2383 values total...", 16685.8]
      }
    }
  ]
}

The wavelength_array contains 2383 values from 2501.1 to 16685.8 nm in ~0.9 nm steps. The example above is abbreviated.
