Abstract
A breath analyzer apparatus includes a breath sampler and a breath analyzer. The breath sampler can include a microelectromechanical (MEMS) preconcentrator to trap and collect volatile organic compounds (VOCs) in a subject's breath. The MEMS preconcentrator can have top facing inlets and outlets. The MEMS preconcentrator can be housed in a preconcentrator cartridge that can be removably positioned in the breath sampler. After the breath sampler is utilized to trap the VOCs in the MEMS preconcentrator, the preconcentrator cartridge can be removed from the breath sampler and inserted into or mounted on the breath analyzer to analyze the trapped VOCs for indication for diseases. A functionalization apparatus utilizes the top facing inlets and outlets of the MEMS preconcentrator to carry out wafer level simultaneous functionalization of multiple MEMS preconcentrators.
