The ProCeas Trace Gas Analyzer combines the picometer (0.001 nm) resolution OFCEAS patented technology with low pressure (100 mBar) patented sampling technology to achieve measurement of trace gases in complex matrices without false positive.

Direct measurement of 200 equidistant data points and 10⁴ instrumental response dynamic range eliminates the need for reference gases and re-zero.

Built-in optical self-diagnostics correct for any variation of signal intensity every 100 millisecond.

Ultra-low sensitivity is guaranteed by pathlengths up to 20 km in less than 25 mL internal volume gas cells.

Signal intensity is further increased (while reducing noise to 4x10^-10 AU per scan) by increase of the purity of the laser beam injected into the cavity (laser bandwidth = 10 KHz)
