The present invention relates to a connector assembly and a battery pack having the same. Specifically, four or more gas chromatography columns are configured for parallel analysis of four or more gaseous samples with detection being effected using a microdetector array comprising four or more microdetectors. One or more acoustic transmitters are set in a distal face of the stabilizer blade to generate acoustic waves. The top heat dissipating device may be thermally coupled with the bottom heat dissipating device through a thermally conductive coupling member to provide a conductive path for heat transfer from the bottom heat dissipating device to the top heat dissipating device.
