摘要：

A new design of a multipass photoacoustic cell intended for FTIR measurements is reported. In spite of the intracell reflections the walt signal is negligible. Comparison with transmission measurements using a fundamental band of COS show a sensitivity equivalent to a 3 m transmission cell. Detection limit for COS is estimated 0.1 ppm corresponding to alpha(min) = 10(-5)/cm.
