Abstract
In an embodiment, an apparatus includes a removable portion having a material and a chemical detection system coupled with the removable portion. The chemical detection system can obtain an amount of the material from the removable portion and determine whether the amount of material obtained from the removable portion includes a predetermined substance. In response to determining that the amount of the material obtained from the removable portion includes the predetermined substance, the chemical detection system can provide a first signal to initiate a first operation of the apparatus. Additionally, in response to determining that the amount of material obtained from the removable portion does not include the predetermined substance, the chemical detection system can generate a second signal to display an alert that indicates the material is not approved by at least one of a manufacturer of the apparatus or a supplier of the apparatus.
