Abstract: We present a detailed chemical analysis on the basis of high-resolution, high signal-to-noise optical spectra of two post-AGE objects IRAS 22223+4327 and IRAS 04296+3429. Both display the unidentified 21 mu m feature in their IR-spectra. The analysis is performed using HR 1865(F0Ib) and HR 1017(F5Iab) as reference stars.
