The invention provides an apparatus that can be used in methods of preparing, amplifying, detecting, and/or optionally selecting for further analysis the genomic material from an organism for the rapid detection and/or classification of an organism in a sample (e.g., screening for, identifying, quantifying, and/or optionally further analyzing, e.g., sequencing, the genomic material of the organism). The invention further provides methods of using the apparatus, e.g., in combination with novel SGP primers for improved use in waveform-profiling methods of DNA amplification. It is an object of the invention to provide an apparatus for fully automated analysis of genomic material, and multiple methods of using the apparatus that are beneficial to society, e.g., the apparatus may be used in methods of screening for, identifying, quantifying, and/or selecting genomic material for further analysis (e.g., sequencing) in relation to monitoring a source for the presence of contaminating organisms.
