Components with strong outgassing

Painted shields

Painted shields

Used as a shield for scattered light, painted plates are normally attached to the CCD chip. Possibly caused by the black paint, numerous new lines at temperatures around 100° C occured:

Line [amu] Fragment ions
36 probably H35Cl+
38 probably H37Cl+
53 C4H5+ ?
57 C4H9+
58 (Acetone)
69 CF3+
77 (Phenyl)

Spectrum of the painted shields at 115° C.
