The invention relates to a process for deblocking substantially a blocked, detectably labeled oligonucleotide by contacting the blocked detectably labeled oligonucleotide with an effective amount of a nucleophilic amino compound under conditions that result in substantial deblocking of the oligonucleotide, thereby giving the substantially deblocked oligonucleotide. During a set-up operation, the encryption key is provided to the PLD, which generates an ID code upon power-up. This supporting section is structured so that the filler is oriented along the direction along which the plurality of ejecting orifices are arranged.
