Toy Brick

 EnviroESCA sample plate with toy brick

A toy brick on an EnviroESCA sample plate. The sample was analysed without any pretreatment, drying, cleaning procedure, electrical contacting, or glueing.

The image was recorded with one of the three digital microscopes at the EnviroESCAs Analysis Module. The metal pipe coming from the lower left corner allows for dosing of gases directly onto the analyzed region of the sample.

After evacuating the Sample Environment to 1*10-5mbar a survey spectrum was measured. Due to charging of the sample no clear structure can be observed. Providing a 1mbar atmosphere of air results in an Environmental Charge Compensation. Now, peaks in the O 1s and C 1s Region are clearly observable.

The above shown detail spectra clearly show signals from Oxygen and Carbon on the surface of the Toy Brick when 1 mbar of air is provided in the analysis chamber.
