sample concentrations tend to be very dilute and raman spectrometers are operating at the lower end of their capabilities. measurement times of - minutes to obtain a signal are quoted in the literature , . in this analysis, a design space was generated to produce a multivariate calibration set for a chemically...
glass; another type is obtained by letting the glass sheet undergo a quick quenching process after being heated up to a high temperature. this is a pure physical approach used for tempered fire-resistant glass; the third type uses the float glass method to melt and form the fire-resistant glass with modified...
