A fragment condensation process for the synthesis of analogs of parathyroid hormone and parathyroid hormone related peptide, in which amino acid residues form a synthetic amphipathic \u03b1-helix, is provided. In an interleave selecting unit as the interleave pattern control device, calculation units individually calculate the signal quality of the repetition synthesization result of pilot signals deinterleaved according to the candidates of interleave patterns. The motor housing is arranged as a separate modular motor unit, which can be attached to the ship by way of a fastening arrangement. The protection switches used may be 1\xd7N, 2\xd7N or 3\xd7N MEMS optical switches. Related systems and peptide biomarker screening methods are also provided.
