The subject invention discloses devices and methods for sampling an analog signal in order to perform data analysis. More particularly, the subject invention provides a time-resolved, direct, high-speed sampling of analog output of a detector, in order to capture harmonic content of the signal without the need to modulate the detection system. The sampling devices and corresponding methods include a detector module for measuring a response generated from a sample, an analog to digital converter for sampling the analog signal, received from the detector module, and converting it into a digital signal; and a logic circuit coupled to the converter for processing the digital signal. The sampling rate of the converter is faster than the response of the sample, and the logic circuit is capable of analyzing the digital signal acquired from the converter and continuously transferring the data analysis obtained to a storage or display device.
