Question

could you please paraphrase highlighted part, thanks

characterized. Raman spectroscopy measurements were carried out using PerkinElmer Raman Station 200F utilizing an excitation wavelength of 785 nm, 100 um spot size, 1 s exposure time, and an average of 20 acquisitions. The Raman spectra were background corrected using an in- house developed wavelet transform/signal removal algorithm23

Answer 1

Raman Spectroscopy measurments were carried out by using Perkin Elmer station 220F instrument with a maximum absorbtion of wavelength of the sample up to 785nm. The sample size is 100 $\mu$ M and the instrument can acquire 20 readings in less than 1 second, and gives out a spectrum an average of those 20 acquisitions. The Raman spectra obtained by this instrument have clear signal enhancement by reducing the signal to noise ratio with help of a computer generated algorithm.
